Think of it as one of the most important classifications in your craft. Choosing the right glass is the first step to creating beautiful, durable fused pieces, and understanding COE is fundamental to that process. COE 90 is a specific type of glass formulated to be compatible for fusing, making it a favorite for everyone from beginners to professional artists. It\u2019s known for its reliability, extensive color palette, and the high-quality results it produces.<\/p>\n<h3>What Does &#8220;Coefficient of Expansion&#8221; Actually Mean?<\/h3>\n<p>First things first, &#8220;COE&#8221; stands for Coefficient of Expansion. In simple terms, it\u2019s a measurement of how much glass expands when it gets hot and shrinks as it cools down. This is incredibly important in glass fusing because if you try to melt two pieces of glass together that expand at different rates, they\u2019ll pull apart and crack as they cool\u2014a frustrating lesson many of us learn the hard way! All glass marked as COE 90 has the same expansion rate, which means you can fuse any COE 90 pieces together\u2014sheets, stringers, frit\u2014and they will bond perfectly without creating stress in the final piece.<\/p>\n<h3>Why Artists Love COE 90 for Fusing<\/h3>\n<p>Artists gravitate toward COE 90 glass for a few key reasons, but it really  comes down to reliability and creative freedom. This glass is known for its consistency, which means you can trust it to behave predictably in the kiln time after time. This is a huge deal when you&#8217;re working on a complex piece that requires multiple firings. Furthermore, the range of colors, textures, and forms available in COE 90 is massive, largely thanks to industry leaders like Bullseye Glass. Whether you need vibrant sheet glass, delicate stringers, or shimmering dichroic coatings, you can find it in COE 90, giving you an incredible palette to bring your vision to life.<\/p>\n<h3>What Makes COE 90 Glass So Special?<\/h3>\n<p>Beyond its compatibility, COE 90 glass has some distinct physical properties that make it great to work with. It\u2019s typically made using a double-rolled process, which results in a flatter, more uniform sheet. This is a fantastic benefit because it helps minimize trapped air bubbles between layers, leading to a smoother, more professional finish. The standard thickness is about 3mm, a versatile size for layering and slumping into molds. COE 90 also has a slightly higher working temperature than other types, like COE 96. This means it needs a bit more heat to melt, which can give you more control over the fusing process, especially for intricate designs.<\/p>\n<h3>Beyond Fusing: Other Uses for COE 90 Glass<\/h3>\n<p>While COE 90 is the undisputed champion of the kiln, its creative potential extends far beyond fusing. The same properties that make it so reliable for kiln-forming\u2014its consistency and vast selection of colors and forms\u2014also make it a fantastic choice for other glass art disciplines. If you&#8217;ve built up a collection of COE 90 glass for your fusing projects, you might be surprised to learn how you can use those same materials for torchwork or even to add unique elements to your stained glass pieces. This versatility makes it one of the most valuable and adaptable materials you can have in your studio, allowing you to explore new techniques without having to invest in an entirely new set of supplies.<\/p>\n<h4>Using COE 90 for Lampwork and Torchwork<\/h4>\n<p>If you&#8217;ve ever been interested in making your own glass beads or small sculptures with a torch, your COE 90 supplies are ready for the job. The core principle of compatibility is just as critical in lampworking as it is in fusing. When you build a bead by melting different colors of glass rods onto a mandrel, each layer must expand and contract at the same rate to prevent it from cracking apart as it cools. Because COE 90 glass is specifically designed for this, it\u2019s an excellent material for torchwork. You can use rods, stringers, and even frit to create intricate patterns and detailed designs, confident that your finished piece will be strong and stable after it&#8217;s been properly annealed.<\/p>\n<h4>Incorporating Fusible Glass in Stained Glass Projects<\/h4>\n<p>The incredible variety of colors and textures available in COE 90 glass makes it a tempting addition to traditional stained glass work. While you can&#8217;t fuse it directly to standard stained glass (which has a different COE), you can absolutely use it as a component. Think of using a sheet of shimmering iridescent or uniquely patterned fusible glass as a panel in your next stained glass project, cutting it and framing it with lead came or copper foil just as you would any other glass. You can also create small, fused elements like cabochons, jewels, or decorative accents in your kiln and then incorporate them into a larger stained glass piece. This hybrid approach opens up a world of creative possibilities, allowing you to combine the precision of stained glass with the painterly effects of fusing.<\/p>\n<h2>A Guide to the Different Types of COE 90 Glass<\/h2>\n<p>When you first get into glass fusing, you probably picture large, colorful sheets of glass. And while that\u2019s a huge part of it, the world of COE 90 glass is so much richer and more varied. Think of it like a painter\u2019s toolkit\u2014you wouldn\u2019t just use one type of brush, right? The same goes for glass. Beyond the foundational sheets, you have access to powders, crushed glass, thin rods, and even glass with a magical, color-shifting coating that adds an incredible shimmer to your work. These different forms are your secret weapons for creating truly unique art.<\/p>\n<p>Learning to work with these materials is what separates good glass artists from great ones. By combining textures and shapes, you can create pieces with incredible depth and personality. You can achieve painterly effects with powders, draw fine lines with stringers, or add a pop of iridescent sparkle that catches the eye. Each type has its own unique properties and applications, and understanding them will open up a whole new level of creativity in your kiln. It&#8217;s all about knowing what tool to reach for to bring your vision to life. Let\u2019s break down the essential forms of COE 90 glass so you can start experimenting with confidence.<\/p>\n<h3>Sheet Glass: The Foundation of Your Project<\/h3>\n<p>Sheet glass is the foundation of most fused glass projects. It\u2019s your canvas. You can use it as a solid base layer, cut it into precise shapes for mosaic work, or stack different colors to create depth. Most sheets come in a standard 3mm thickness, which is a great all-purpose size for kiln work. For projects where clarity is key, look for double-rolled glass. It tends to be flatter and more uniform, which helps minimize the chances of trapping pesky air bubbles between your layers during firing. Whether you\u2019re making a simple coaster or a complex piece of wall art, you\u2019ll almost always start with a piece of high-quality COE 90 sheet glass.<\/p>\n<h4>Exploring Styles: Iridized, Opal, and Streaky Glass<\/h4>\n<p>Once you have your base, you can explore different styles of sheet glass to add personality to your work. Iridized glass, for example, has a thin metallic coating that gives it a beautiful, rainbow-like shimmer. You can fire it with the coating facing up for a vibrant, metallic sheen or face it down against another piece of glass for a more subtle, antiqued effect. Opal glass is your go-to for solid, opaque color. Since light doesn\u2019t pass through it, it\u2019s perfect for creating backgrounds or bold design elements that stand out. Then there\u2019s streaky glass, which has two or more colors swirled together, creating a sense of movement and organic texture in a single sheet.<\/p>\n<h4>Finding Unique Patterns and Holiday Themes<\/h4>\n<p>Beyond color and finish, you can find specialty COE 90 glass with pre-fired patterns, from delicate florals to bold geometric designs. These sheets are fantastic for adding intricate details without having to cut and place tiny individual pieces. You can also find glass perfect for holiday-themed projects, featuring festive colors or even patterns like snowflakes or spiderwebs. Using these specialty sheets can be a great source of inspiration, allowing you to build an entire piece around a single, stunning element. Whether you use them as the main feature or as small accent pieces, patterned glass sheets are a great way to add a unique touch to your art.<\/p>\n<h3>Adding Texture with Frit and Powder<\/h3>\n<p>If sheet glass is your canvas, think of frit and powder as your paint. Frit is simply glass that has been crushed into small chunks, available in various grain sizes from coarse to fine. Powder is even finer, with a consistency like sand. These materials are fantastic for adding texture, creating gradients, and &#8220;painting&#8221; designs onto your glass. You can sprinkle them on to create a speckled effect, layer them for soft color blends, or use them with stencils for precise patterns. Frit and powder give you a level of detail and artistic control that\u2019s hard to achieve with sheet glass alone, making them essential for more intricate work.<\/p>\n<h4>Understanding the Vast Color and Size Variety<\/h4>\n<p>One of the best parts about working with COE 90 is the sheer variety at your fingertips. The color palette is enormous, covering everything from bold primary colors like red and blue to subtle ambers, pinks, and grays. But it doesn&#8217;t stop there. Beyond the basic forms, you can find an entire world of specialty glass to play with. You can incorporate thin glass rods called stringers to draw fine lines, add patterned murrine for intricate details, or use precut shapes for quick and consistent designs. This incredible range means you&#8217;re never limited in how you can express your ideas. The selection of COE 90 glass available today gives you a massive artistic vocabulary to bring any concept to life, whether you&#8217;re aiming for a simple, elegant design or a complex, multi-layered piece.<\/p>\n<h3>Creating Detail with Stringers and Rods<\/h3>\n<p>Stringers and rods are essentially thin strands of glass that look like spaghetti or noodles. Stringers are typically 1mm thick, while rods are a bit thicker. They are perfect for drawing lines, outlining shapes, or adding delicate, web-like details to your projects. You can lay them straight across your base glass or gently heat them with a torch to bend them into organic curves before firing. They can be arranged to form patterns, create lettering, or even mimic the veins in a leaf. Using stringers and rods is an easy way to add a graphic, linear element to your fused glass art.<\/p>\n<h3>The Magic of Dichroic Glass<\/h3>\n<p>For a touch of magic, nothing beats dichroic glass. This glass is coated with micro-thin layers of metallic oxides that cause it to reflect different colors depending on the viewing angle. The effect is a stunning, iridescent shimmer that can make any piece pop. Because it\u2019s so eye-catching, dichroic glass is a favorite for jewelry makers and artists creating decorative pieces. You can use a small piece as a brilliant accent or make it the star of the show. You can find CBS Dichroic glass in many forms, including sheets and frit, allowing you to add that vibrant, color-shifting element to any part of your design.<\/p>\n<h4>Choosing the Right Base: Black, Clear, or Colored<\/h4>\n<p>Your choice of base glass is one of the most important artistic decisions you&#8217;ll make. It\u2019s the canvas that sets the stage for everything else you add. A clear base creates a sense of openness and lets light pass through, making it perfect for suncatchers or dishes where you want the focus on the layered elements. A black base, on the other hand, offers a dramatic backdrop that makes vibrant colors and dichroic glass absolutely sing. And using a colored base integrates the foundation into the design itself, adding another layer of depth and emotion to your work. Each option provides a different starting point, so consider the final look you\u2019re aiming for before you even make your first cut.<\/p>\n<p>Let&#8217;s break down when to use each. Reach for clear sheet glass when you want your design elements to float or when transparency is key. Using a double-rolled clear sheet can also help you achieve a flatter, more uniform surface, which is great for minimizing trapped air bubbles. Choose a black base when you need maximum contrast. It\u2019s the ultimate choice for making iridescent and dichroic glass pop, creating a bold, graphic statement. A colored base is your go-to when you want to build a rich, layered piece. A soft blue can evoke a sky or seascape, while a warm amber can give your project an earthy feel, showing how the base itself becomes an active part of your art.<\/p>\n<h3>Beyond the Basics: Murrine, Precuts, and More<\/h3>\n<p>Once you&#8217;re comfortable with the core components of your glass toolkit\u2014sheets, frit, and stringers\u2014you can start exploring the really fun stuff. The world of COE 90 glass is filled with specialty items that can add incredible personality and intricate detail to your work. These are the elements that let you move beyond basic designs and create pieces that are truly one-of-a-kind. From tiny, pre-made patterns to paper-thin glass shards, these unique forms open up new creative avenues. Think of them as the finishing touches that can define your artistic style, allowing you to add complex details with surprising ease. Experimenting with these materials is a fantastic way to push your skills and discover new techniques in your glass fusing practice.<\/p>\n<h4>Decorative Embellishments: Cane, Dots, and Wafers<\/h4>\n<p>Decorative embellishments are your secret weapon for adding detail and flair without spending hours on intricate cuts. Murrine, for example, are tiny slices of pre-made patterned glass cane that look like little pieces of candy\u2014perfect for creating flowers or geometric designs. Glass cane itself is a thicker rod, often with its own internal stripes or patterns, great for making bold lines. You can also find precut glass shapes, which are a huge time-saver when you need a perfect circle, star, or heart. And for creating uniform patterns, glass dots and wafers are small, pre-fired discs that add clean, consistent circular elements to your design, giving your piece a polished and professional look.<\/p>\n<h4>Unique Forms: Casting Billets, Confetti, and Crinklized Glass<\/h4>\n<p>If you&#8217;re ready to venture into more sculptural or textural work, there are some unique forms of COE 90 glass to explore. Casting billets are thick, solid blocks of glass designed to be melted down inside a mold in your kiln. This process, known as glass casting, allows you to create three-dimensional objects like bowls, sculptures, or thick pendants. On the other end of the spectrum is confetti, which are paper-thin shards of glass. When layered, they create delicate, watercolor-like effects with soft, blended edges. These unique forms push the boundaries of what you can do with a flat sheet of glass, inviting you to experiment with dimension, texture, and form in exciting new ways.<\/p>\n<h2>Who Are the Best COE 90 Glass Suppliers?<\/h2>\n<p>When you\u2019re ready to buy glass, you\u2019ll find a few key players that artists consistently trust for their quality and reliability.

They might not have the same massive catalog as the industry giants, but what they do, they do exceptionally well. Taking the time to explore the full selection at a comprehensive supplier can introduce you to these hidden gems. Finding a special sheet of glass from a boutique brand can be the spark of inspiration that leads to your next favorite project.<\/p>\n<h2>How to Choose High-Quality COE 90 Glass<\/h2>\n<p>When you\u2019re ready to buy glass for your next project, it\u2019s easy to get swept up in all the beautiful colors and textures. But the best glass isn\u2019t just about looks\u2014it\u2019s about how it performs in the kiln. Understanding a few key characteristics of quality glass will save you from frustrating cracks and disappointing results. Think of it as getting to know your materials before you create. By paying attention to compatibility, temperature, and working properties, you can ensure your finished pieces turn out exactly as you envisioned.<\/p>\n<h3>Why Compatibility Is Non-Negotiable<\/h3>\n<p>The golden rule of glass fusing is simple: stick to one COE. The Coefficient of Expansion (COE) tells you how much glass expands when heated and shrinks when cooled. For a successful fuse, all the glass in your project must expand and contract at the same rate. Mixing COE 90 glass with COE 96, for example, is a recipe for disaster. The different rates will create stress as the piece cools, leading to cracks or even causing your project to break apart. To avoid this, always double-check that every piece of glass, frit, and stringer you use has the same COE. It\u2019s a great habit to keep your COE 90 and COE 96 supplies stored separately in your studio.<\/p>\n<h3>Decoding Firing Temperatures<\/h3>\n<p>Every type of glass has a personality, and that includes its preferred temperature for fusing. COE 90 glass generally requires a bit more heat to melt than COE 96. For instance, a tack fuse\u2014where the layers of glass stick together but retain some dimension\u2014happens around 1370\u00b0F for COE 90. Knowing these temperature targets is essential for controlling the outcome of your work. Firing too hot or too cold can mean the difference between a perfectly fused piece and a melted puddle. Using the right kilns and following a precise firing schedule for your specific glass will give you consistent, beautiful results.<\/p>\n<h3>How Does the Glass Behave in the Kiln?<\/h3>\n<p>Beyond COE and temperature, it\u2019s important to understand how your glass will behave once things heat up. As a beginner, one of the most common challenges is learning how to stack layers properly. If you trap large pockets of air between your glass pieces, that air will expand in the kiln and can create bubbles, distort your design, or even crack your project. To get better results, make sure your layers fit snugly together. When you\u2019re working with molds to slump or drape glass, understanding how the material will move and stretch is key to achieving the shape you want without any unwanted surprises.<\/p>\n<h3>Choosing the Right Colors and Textures<\/h3>\n<p>Now for the fun part! The creative possibilities with COE 90 glass are nearly endless, thanks to the incredible variety of colors and textures available. You can find everything from solid opaque sheets to streaky, iridescent, and transparent styles that add depth and life to your art. The right combination can completely transform a simple design into a stunning piece. Don\u2019t be afraid to play with different options to see how they interact. Some colors create unique chemical reactions when fused next to each other, producing beautiful new hues and effects. Making small test tiles is a fantastic way to preview your combinations before committing to a larger project.<\/p>\n<h2>Where Can You Buy COE 90 Glass?<\/h2>\n<p>Finding a reliable supplier is one of the most important steps in your glass fusing journey. You need a place that not only has the colors and styles you want but also packs your precious glass with care. Whether you prefer the convenience of online shopping or the hands-on experience of a local store, you have plenty of great options for sourcing high-quality COE 90 glass. Let\u2019s walk through where to find the best materials for your next project.<\/p>\n<h3>Our Favorite Online Glass Suppliers<\/h3>\n<p>Shopping online gives you access to a massive inventory right at your fingertips. Here at ArtGlassSupplies.com, we offer a comprehensive selection of COE 90 glass, from vibrant Bullseye sheets to dazzling CBS dichroic glass. Other trusted online specialists like <a href=\"https:\/\/www.glacialartglass.com\/collections\/coe-90\" target=\"_blank\" rel=\"nofollow noopener\">Glacial Art Glass<\/a> and <a href=\"https:\/\/www.dlartglass.com\/glass-by-coefficient\/90-coe\" target=\"_blank\" rel=\"nofollow noopener\">D&amp;L Art Glass<\/a> also provide extensive collections for fusers.

You can browse hundreds of colors, textures, and forms\u2014like frit, stringers, and powders\u2014all in one place, making it easy to find exactly what you need for your artistic vision.<\/p>\n<h3>Shopping Local for Your Glass<\/h3>\n<p>There\u2019s something special about seeing glass in person. If you have a local art supply store, it\u2019s worth a visit. You can hold a sheet up to the light, see its true colors, and get a feel for its texture without relying on a screen. Many artists find their go-to local spots by searching for shops that specialize in glass, like Rainbow Glass or The Glass Underground. As some artists have shared in online forums, building a relationship with a local supplier can also lead to great advice and a sense of community.<\/p>\n<h3>How to Compare Prices Like a Pro<\/h3>\n<p>When you\u2019re comparing prices, make sure you\u2019re looking at more than just the number. Check the dimensions of the sheet glass\u2014a 10&#215;10 inch piece will obviously cost less than a 24&#215;48 inch one. Pay attention to the brand and type of glass, as specialty glass like dichroic will be more expensive than standard clear or colored sheets. For example, a large sheet of Bullseye Tekta Clear might run you around $85, which can be a helpful benchmark. Always compare apples to apples by looking at the price per square foot to understand the true cost.<\/p>\n<h4>A Look at Typical COE 90 Glass Prices<\/h4>\n<p>Budgeting for your glass art is much easier when you know what to expect. Prices for COE 90 glass can range from just a few dollars for small accents to several hundred for large sheets or bulk packs. For instance, you can find small bags of crushed glass frit starting around $4, making it an affordable way to add color and texture. Specialty items like intricate murrine pieces or shimmering dichroic glass will naturally cost more, often falling in the $15 to $20 range for smaller cuts. When it comes to sheet glass, the price depends heavily on size, color, and special finishes. Exploring a wide selection of COE90 glass will help you find the perfect materials that fit both your creative vision and your budget.<\/p>\n<h3>What to Know About Shipping Glass<\/h3>\n<p>Shipping glass requires special care, and it\u2019s something to factor into your budget. Because glass is heavy and fragile, shipping costs can add up. Many online retailers offer flat-rate shipping on orders over a certain amount, which can save you a lot of money, but be aware that oversized sheets may have extra fees. Before you finalize your purchase, always read the store\u2019s shipping policy. This will help you understand how they pack their glass, what their breakage policy is, and if there are any restrictions on what they can ship to your location.<\/p>\n<h4>Special Shipping Considerations for Glass<\/h4>\n<p>Getting your beautiful new glass delivered safely is just as important as choosing the right colors. Because glass is so fragile, reputable suppliers take packaging very seriously. Expect your order to arrive with specialized protection, like foam padding and corner protectors, to absorb any bumps along the way. Each sheet should be <a href=\"https:\/\/packmojo.com\/blog\/shipping-glass-items-guide\/\" target=\"_blank\" rel=\"nofollow noopener\">wrapped individually<\/a> to prevent pieces from clashing during transit. It\u2019s also smart to review a retailer&#8217;s breakage policy and consider shipping insurance for peace of mind, especially on larger orders. While many online stores offer flat-rate shipping to help manage costs, remember that oversized sheets often come with additional fees. Always take a moment to read the shipping policy before you check out so you know exactly what to expect when that exciting package arrives at your door.<\/p>\n<h2>How to Shop Smart and Store Your Glass<\/h2>\n<p>Once you\u2019ve found the perfect glass for your project, the next step is to make a smart purchase and take good care of your new materials. A little planning when you buy and some simple care in your studio can make a huge difference in your budget and the quality of your finished pieces. Let\u2019s walk through a few practical tips for shopping wisely and storing your glass correctly so you can set yourself up for success from the very beginning.<\/p>\n<h3>Understanding How Glass is Sold: By Weight, Piece, or Sheet<\/h3>\n<p>When you shop for glass, you\u2019ll notice it\u2019s sold in a few different ways, and understanding the lingo will help you buy exactly what you need. The most common format is sheet glass, which is sold by its dimensions\u2014you\u2019ll see standard sizes like 5&#215;10 or 10&#215;10 inches. This is straightforward for projects where you\u2019re cutting shapes from a flat canvas. However, other essential materials like frit and powder are sold by weight, typically in jars or bags measured in ounces or pounds. Specialty items, like precut shapes or decorative murrine, are often sold by the piece or in small packs.<\/p>\n<p>Even when you buy by the sheet, weight is still a factor, especially for projects that involve filling molds. A helpful rule of thumb is that a square foot of standard 3mm (1\/8&#8243;) thick glass weighs about 1.6 pounds. Knowing this helps you calculate how much glass you need to fill a specific volume, preventing you from coming up short. Whether you&#8217;re buying a precise sheet or gathering scrap glass for a casting project, understanding the relationship between size and weight ensures you get the right amount of material every time.<\/p>\n<h3>Should You Buy Your Glass in Bulk?<\/h3>\n<p>If you find yourself using certain colors or types of glass often, buying in bulk is one of the best ways to reduce your costs. Think of it as stocking your pantry\u2014having your go-to supplies on hand saves you from placing small, frequent orders. Many suppliers offer discounts on larger quantities of COE 90 fusing glass, which adds up to significant savings over time. Plus, you can often qualify for free shipping by meeting a certain order threshold, making each sheet of glass even more economical. It\u2019s a simple strategy that helps your art budget go much further.<\/p>\n<h3>How to Find the Best Deals on Glass<\/h3>\n<p>Keeping your art supplies stocked doesn\u2019t have to break the bank. It\u2019s always a good idea to keep an eye out for promotional offers and sales. Many online retailers run deals like a certain dollar amount off a minimum purchase, which is the perfect opportunity to stock up on essentials or try something new. Subscribing to newsletters from your favorite suppliers is a great way to stay in the loop so you never miss a chance to save. A little patience and planning can lead to great deals on the materials you love.<\/p>\n<h3>The Right Way to Store Your Glass Sheets<\/h3>\n<p>How you store your glass is just as important as how you fire it. Proper storage protects your investment and ensures your materials are in perfect condition when you\u2019re ready to create. Keep your glass in a cool, dry place away from direct sunlight, which can affect certain colors over time. The most important rule? Avoid stacking sheets directly on top of each other. Always place a protective layer, like thin foam or paper, between them to prevent scratches and chips that can become weak points during firing.<\/p>\n<h3>Essential Safety Tips for Handling Glass<\/h3>\n<p>Working with glass requires care and attention, both for your safety and for the material itself. Always wear safety glasses and consider wearing gloves to protect your hands from sharp edges. When it comes to the technical side, proper handling extends to the firing process. To ensure your piece stabilizes correctly without internal stress, you need to follow the right annealing schedule in your kiln. For most COE 90 glass, the annealing temperature is right around 900\u00b0F, but always check the manufacturer\u2019s specific recommendations for the best results.<\/p>\n<h2>Ready to Fuse? Your First COE 90 Project<\/h2>\n<p>Ready to turn that beautiful sheet of glass into a finished piece? Once you have your supplies, the real fun begins. Fusing glass is a process of experimentation and learning, but starting with a solid foundation will help you get beautiful results faster. Let&#8217;s walk through the basic steps and some common pitfalls to watch out for as you begin your journey with COE 90 glass. Think of this as your friendly guide to getting those first few projects out of the kiln and into your hands.<\/p>\n<h3>Your Essential Fusing Toolkit<\/h3>\n<p>Before you can start creating, you\u2019ll need to set up your workspace. The star of the show is, of course, your COE 90 glass. This includes not just sheet glass but also fun accents like murrine, frit, stringers, and precut glass shapes that add texture and detail to your work. Beyond the glass itself, you&#8217;ll need a few key tools: a reliable glass cutter, breaking pliers for clean snaps, and safety glasses (never skip these!). A kiln is the most significant piece of equipment, as it\u2019s where the magic of fusing happens. Finally, have some kiln wash and a kiln shelf on hand to prevent your masterpiece from sticking.<\/p>\n<h3>Simple Steps for a Successful First Fuse<\/h3>\n<p>One of the best things about COE 90 glass is its versatility. This glass is perfect for a huge range of art projects, from jewelry and beads to sculptures, mosaics, and especially kiln-forming. If you&#8217;re just starting, I recommend a simple project like making a set of coasters or a small decorative dish. Using slumping and draping molds can give your piece a professional shape with minimal effort. Start with a clear base layer and add a few colorful elements on top. This helps you get a feel for how the glass behaves in the kiln without getting overwhelmed by a complex design.<\/p>\n<h3>Getting Your Kiln Temperatures Just Right<\/h3>\n<p>Temperature is everything in glass fusing. Different types of glass melt at slightly different temperatures, and knowing your numbers is crucial for success. For example, while COE 96 glass typically tack fuses around 1350\u00b0F, COE 90 needs a little more heat, tack fusing closer to 1370\u00b0F. This might seem like a small difference, but it can completely change the outcome of your project. Your kiln is your most important tool for managing heat, so get to know its settings. Always follow a tested firing schedule for the specific glass you\u2019re using and the result you want, whether it\u2019s a tack fuse, full fuse, or slump.<\/p>\n<h3>Common Firing Mistakes (and How to Avoid Them)<\/h3>\n<p>It\u2019s completely normal to have a few duds when you\u2019re starting out, but you can avoid some common issues with a little foresight. A frequent mistake is trapping large pockets of air between layers, which can distort your design or even crack the glass. This often happens when you place small pieces between two large sheets. To avoid this, build your layers carefully. Another issue is warping, which happens when glass is over-fired or isn&#8217;t properly supported on the kiln shelf. Following a proper firing schedule is your best defense against over-firing and ensuring your beautiful piece comes out flat and perfectly fused.<\/p>\n<h2>Fuse Like a Pro: Our Top Tips<\/h2>\n<p>Once you have the basics down, you can start refining your technique to get that polished, professional look in every piece. It often comes down to the small details in your prep work and process. Paying close attention to how you stack your glass, prepare your kiln shelf, and manage your firing can make all the difference between a good result and a great one. Let\u2019s walk through a few key tips that will help you create stunning, flawless fused glass art.<\/p>\n<h3>The Art of Layering Glass for Fusing<\/h3>\n<p>How you stack your glass is one of the most important steps in the entire fusing process. When you\u2019re just starting out, it\u2019s easy to trap large pockets of air between layers, especially if you place small decorative pieces between two large sheets. This trapped air has nowhere to go as the glass heats and seals, which can lead to distorted designs, an uneven surface, or even a cracked project. To avoid this, always try to build your design from the bottom up. If you must create a design with potential air traps, leave a tiny, unnoticeable channel to the edge so the air can escape as the COE90 glass heats up.<\/p>\n<h3>Using Kiln Shelves and Separators Effectively<\/h3>\n<p>Think of kiln separators like kiln wash or shelf paper as the non-stick spray of the glass fusing world. Their job is to create a barrier between your project and the kiln shelf or mold, ensuring your piece lifts off cleanly after firing. Using too little separator is a common mistake that can cause your glass to stick to the shelf, or worse, warp or sag because it can\u2019t move freely as it heats and cools. Whether you\u2019re using shelf paper or kiln wash, make sure you have complete, even coverage under your entire project. This simple step protects both your artwork and the shelves inside your kiln.<\/p>\n<h3>Say Goodbye to Pesky Bubbles and Air Pockets<\/h3>\n<p>Beyond the air you might trap between layers, tiny bubbles can also appear from other sources. One culprit is moisture; always make sure your glass is perfectly clean and dry before it goes into the kiln. Another strategy is to adjust your firing schedule. A slower initial heating phase gives any trapped air more time to squeeze out before the edges of your glass fuse together and seal. It\u2019s also worth noting that some bubbles aren&#8217;t from air at all, but from chemical reactions between different types of glass. It\u2019s a great idea to <a href=\"https:\/\/lindsay-designs.net\/blogs\/news\/10-mistakes-beginners-make-when-fusing-glass-and-how-to-avoid-them\" target=\"_blank\" rel=\"nofollow noopener\">run small test pieces<\/a> first to see which combinations create the effects you want\u2014and which to avoid.<\/p>\n<h3>How to Apply Kiln Wash the Right Way<\/h3>\n<p>A flawless kiln wash application is your first line of defense against stuck projects. An uneven or lumpy coat can transfer its texture to the back of your glass, ruining a perfectly smooth finish. To get it right, mix your kiln wash to a smooth, thin consistency, similar to skim milk. Apply it to your shelf or molds in several thin layers rather than one thick one. Let each coat dry completely before applying the next, and alternate your brushstroke direction with each layer (e.g., first coat horizontal, second vertical). This technique builds a durable, even surface that will release your glass beautifully every time.<\/p>\n<h2>How to Troubleshoot Common Fusing Issues<\/h2>\n<p>Every glass artist, from beginner to seasoned pro, has opened a kiln to find a less-than-perfect result. It\u2019s a completely normal part of the creative process! The good news is that most fusing issues are preventable once you know what to look for. When a piece doesn\u2019t turn out as planned, it usually comes down to one of four things: compatibility, your firing schedule, how you handled the materials, or your post-firing checks. Let\u2019s walk through how to spot and solve these common problems so you can get back to creating beautiful work.<\/p>\n<h3>What to Do When Your Glass Isn&#8217;t Compatible<\/h3>\n<p>The golden rule of fusing is to never mix glass with different Coefficients of Expansion (COE). Sticking exclusively with COE 90 glass for a project is the first step to ensuring your piece doesn&#8217;t crack from internal stress. But compatibility goes beyond the COE number. You also need to think about how your layers fit together physically. Beginners sometimes stack glass in a way that traps large pockets of air, especially when sandwiching small decorative pieces between two larger sheets. As the kiln heats up, this trapped air expands, which can lead to distorted designs, uneven surfaces, or even cracked pieces. To avoid this, make sure your glass layers have good surface contact before firing.<\/p>\n<h3>How to Fix a Botched Firing Schedule<\/h3>\n<p>Your kiln is your most important tool, and the firing schedule is the instruction manual for each project. An incorrect schedule is a frequent cause of disappointment. For instance, over-firing or not providing proper support for your glass can cause it to warp or sag excessively, losing its intended shape. Every firing schedule has distinct phases for heating, soaking at a target temperature, and slowly cooling (annealing). Following a proper firing schedule is essential to avoid over-firing the glass and to achieve the exact look you want, whether it\u2019s a tack fuse or a full fuse. Keep a log of what schedules work for your specific kiln and project types.<\/p>\n<h3>Correcting Common Storage and Handling Mistakes<\/h3>\n<p>Sometimes, a project is doomed before it even enters the kiln. Proper preparation of your materials is key. One common mistake is having your glass stick to the kiln shelf. This is almost always caused by an uneven kiln wash application or not using enough separator, like kiln paper. These materials create a crucial barrier between your art and your equipment. When using kiln wash on shelves or molds, apply several thin, even coats and let each one dry completely. If you\u2019re using kiln paper, inspect it for any tears or gaps before placing your glass on top. Also, remember to clean your glass thoroughly to remove any oils or fingerprints that could affect the final result.<\/p>\n<h3>A Quick Checklist for Quality Control<\/h3>\n<p>The moment of truth comes after the kiln has cooled completely. The most critical quality check relates to annealing. To properly anneal glass, you hold it at a steady temperature\u2014typically around 900\u00b0F for COE 90\u2014to allow the internal structure to stabilize and strengthen. Rushing this step or cooling the kiln too quickly creates stress in the glass, which can cause it to crack days or even weeks later. You can check for stress using two pieces of polarized film. Once your piece is out, inspect it for any sharp edges that might need grinding or unwanted bubbles. A successful firing results in a piece that is not only beautiful but also strong and durable.<\/p>\n<h2>Related Articles<\/h2>\n<ul>\n<li>Pop Art Frit Blend Coarse Grain COE90 &#8211; COE90 Frit Blends<\/li>\n<li>Precut Dichroic Glass Circles Rainbow 2 on Clear Glass COE90 &#8211; COE90 Glass<\/li>\n<li>Holey Tears Kiln Casting Mold | Art Glass Supplies &#8211; Casting Molds<\/li>\n<li>Gold Purple Opalescent Frit Balls COE90 &#8211; COE90 Frit Balls<\/li>\n<li>Holey Feather Casting Mold For Kiln Casting| Art Glass Supplies &#8211; Casting<\/li>\n<\/ul>\n<div data-mega-embed=\"true\">\n<p>&nbsp;<\/p>\n<style>.cta-container{display:flex;justify-content:center;margin:40px 0}.cta-button{display:inline-flex;align-items:center;justify-content:center;padding:12px 28px;font-size:16px;font-weight:700;color:#000!important;background-color:#fff!important;border:none!important;border-radius:50px!important;cursor:pointer!important;text-decoration:none!important;transition:all .3s ease-in-out!important;box-shadow:0 0 4px rgba(0,0,0,.15)!important}.cta-button i{margin-right:8px;transition:color .3s ease-in-out!important}.cta-button:hover{color:#2a65c9!important}.cta-button:hover i{color:#2a65c9!important}<\/style>\n<div class=\"cta-container\"><i>\u2191<\/i> Contact Us<\/div>\n<\/div>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>What&#8217;s the real difference between COE 90 and COE 96 glass?<\/strong> Think of it like the difference between two types of clay. While they look similar, they behave differently when you apply heat. The main distinction is their working temperature; COE 90 glass generally needs a bit more heat to melt, which can give you more control over the final look. COE 96 is a little &#8220;softer&#8221; and melts at lower temperatures. Neither is better than the other, but you must stick to one type per project to ensure everything fuses together successfully.<\/p>\n<p><strong>Can I ever mix different COEs in one project?<\/strong> This is one of the few hard-and-fast rules in glass fusing: never mix your COEs. Fusing a piece of COE 90 glass to a piece of COE 96 glass will almost certainly cause your project to crack as it cools. Because they expand and shrink at different rates, they create immense stress when fused together. It\u2019s a great habit to keep your different COE glass supplies stored in separate areas of your studio to avoid any accidental mix-ups.<\/p>\n<p><strong>My fused piece cracked a few days after I took it out of the kiln. What went wrong?<\/strong> This is incredibly frustrating, and it&#8217;s almost always caused by improper annealing. Annealing is the crucial process of slowly cooling the glass to relieve internal stress. If a piece cools too quickly, that stress gets locked inside, making it unstable. It might look perfect coming out of the kiln, but a tiny temperature change or bump can cause it to crack days or even weeks later. The solution is to always follow a complete firing schedule that includes a proper, slow annealing phase.<\/p>\n<p><strong>I&#8217;m just starting out. What are the absolute essentials I need for my first COE 90 project?<\/strong> You can get started without buying an entire store&#8217;s worth of supplies. At a minimum, you&#8217;ll need a selection of compatible COE 90 glass, a quality glass cutter, and a pair of breaking pliers. Safety glasses are non-negotiable. The biggest piece of equipment is your kiln, which is essential for the fusing process. Finally, you&#8217;ll need a kiln shelf and a separator, like kiln wash or shelf paper, to prevent your art from sticking.<\/p>\n<p><strong>Why is my glass sticking to my kiln shelf?<\/strong> This happens when the barrier between your glass and your shelf fails. The culprit is usually your separator\u2014either kiln wash or shelf paper. If you&#8217;re using kiln wash, an uneven or thin application can leave spots where the glass can fuse directly to the shelf. If you&#8217;re using shelf paper, make sure it completely covers the area underneath your project with no gaps. A proper, even coating of a separator is the best way to ensure your piece lifts off cleanly every time.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Find top COE 90 glass suppliers and learn how to choose the best fusing glass for your next project with this practical buyer\u2019s guide.<\/p>\n","protected":false},"author":5,"featured_media":723,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-724","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-glass-fusing"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/posts\/724","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/comments?post=724"}],"version-history":[{"count":7,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/posts\/724\/revisions"}],"predecessor-version":[{"id":1150,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/posts\/724\/revisions\/1150"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/media\/723"}],"wp:attachment":[{"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/media?parent=724"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/categories?post=724"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/tags?post=724"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
