You know that magical, rainbow-like shimmer you see in some glass art? That’s the work of dichroic glass. Its brilliant, metallic effect can turn a simple project into a showstopper. The secret is a high-tech coating that reflects one color while letting another pass through, creating that signature dynamic look. This guide gives you everything for successful dichroic glass fusing. We’ll help you choose the right dichroic glass sheets, avoid common mistakes, and start your first project with confidence. You’ll learn the science behind the shimmer and the practical steps for a perfect fuse.

Key Takeaways

• Always Match Your Glass COE: To prevent cracks, every piece of glass in your project must have the same Coefficient of Expansion. Whether you choose COE 90 or COE 96, stick with one system for all your layers to ensure your final piece is strong and beautiful.
• Cap and Clean for a Flawless Finish: The metallic coating on dichroic glass is delicate. Always clean your glass thoroughly to remove oils and dust, then protect the coating by capping it with a clear layer. This simple prep work prevents flaws and makes the colors look deep and vibrant.
• Understand How to Layer and Fire: Remember two critical rules for the kiln: never place two coated sides together, as they won’t fuse, and always use a firing schedule designed for your specific glass. Proper layering and firing are essential for a successful, professional-quality result.

So, What Is Dichroic Fusible Glass?

If you’ve ever seen a piece of glass that seems to magically shift colors as you turn it in the light, you’ve likely encountered dichroic glass. It’s a captivating material that adds a brilliant, metallic shimmer to any project, making it a favorite for everything from delicate pendants to bold art installations. But what makes it so special? The secret is a micro-thin, multi-layer coating of metals and oxides vaporized onto the surface of the glass in a vacuum chamber. This high-tech process, originally developed for aerospace applications, is what gives the glass its signature characteristic: displaying two different colors depending on the viewing angle.

The term “dichroic” literally means “two-colored,” and it perfectly describes this dynamic effect. As light hits the surface, the coating acts like a filter, reflecting one color while allowing another to pass through. This special glass is also fusible, which means it’s specifically designed to be melted and fused with other compatible glass sheets in a kiln. Whether you’re working with COE 90 or COE 96 glass, you can find dichroic options that will add an incredible pop of color and dimension to your fused art. It’s a fantastic way to make your work stand out and give it a professional, high-quality finish that truly shines.

The Science Behind the Shimmer

The mesmerizing shimmer of dichroic glass comes from the way its unique coating interacts with light. Think of the rainbow sheen on a soap bubble or a drop of oil in a puddle; the principle is similar. When light hits the microscopic layers of the dichroic coating, some light wavelengths are reflected back to your eye, while others pass straight through. Because the reflected color and the transmitted color are different, the glass appears to change hues as you move it. This constant play of light creates a vibrant, iridescent effect that is impossible to ignore. It’s this dynamic quality that makes dichroic glass a favorite among artists for creating eye-catching pendants, earrings, and focal points in larger art pieces.

A Closer Look at the Dichroic Coating

The dichroic coating is typically applied to a base of either clear or black glass. A black base tends to make the reflective colors appear more intense and dramatic, while a clear base offers more versatility for layering. The coating itself is quite delicate and can be scratched or damaged during the firing process if not handled correctly. To protect it, artists almost always “cap” the dichroic layer with a piece of clear glass. This means placing a clear sheet on top of the coated side before firing. Capping not only safeguards the coating but also gives the finished piece a smooth, glossy surface and enhances the depth of the colors.

A Brief History of Dichroic Glass

Believe it or not, the concept of dichroic glass isn’t new. Its history stretches all the way back to ancient Rome. The most famous example is the Lycurgus Cup, a 4th-century Roman artifact that looks green in normal light but glows a stunning red when lit from within. This incredible piece demonstrates the core principle of dichroic glass, even though the Romans didn’t have the technology we use today. The name itself, “dichroic,” literally means “two-colored,” which perfectly captures how the glass displays different colors depending on how you view it. It’s this ancient magic, refined by modern science, that gives us the beautiful material artists love to work with.

From Ancient Rome to Modern Aerospace

So how did we get from an ancient Roman cup to the vibrant sheets of glass in your studio? The modern dichroic glass we use today is a direct result of research from a rather unexpected place: NASA. In the mid-20th century, scientists needed a way to protect astronauts and satellite instruments from the harsh glare of the sun and cosmic radiation. They developed a process of coating glass with microscopically thin layers of metal oxides in a vacuum chamber. This high-tech coating was the perfect solution for their aerospace needs, but it also had a beautiful side effect—that stunning, color-shifting shimmer. It wasn’t long before artists discovered this material and began incorporating it into their work, bringing a piece of space-age technology into the world of glass art.

Your Guide to Dichroic Glass Types

When you first start looking at dichroic glass, the sheer variety can feel a little overwhelming. You’ll find it in every color imaginable, with different textures, patterns, and on different types of base glass. But once you understand the main characteristics, choosing the right sheet for your project becomes much easier and a lot more fun. The three key things to consider are the glass COE, its texture and finish, and its specific color or pattern. Breaking it down this way helps you find the perfect piece to bring your creative vision to life.

COE 90 vs. COE 96

If you’re new to glass fusing, the term COE, or Coefficient of Expansion, is one of the most important things to learn. It simply measures how much glass expands when heated and shrinks when cooled. For a fused piece to be strong and stable, all the glass you use must have the same COE. Mixing COEs will cause stress and cracking as the piece cools.

The two industry standards you’ll work with are COE 90 and COE 96. Neither is better than the other; it’s just a matter of sticking with one for each project. Many artists pick one and build their entire studio collection around it to avoid any mix-ups.

Beyond Sheets: Other Forms of Dichroic Glass

Frit, Firestrips, and More

While dichroic sheets are fantastic for creating a bold, shimmering base, the real fun begins when you start playing with its other forms. Think of these as your secret weapons for adding texture, fine details, and unexpected pops of color. Materials like frit, stringers, and confetti let you get more granular with your designs, giving you more control and opening up a whole new world of creative possibilities for your fused glass art. They allow you to move beyond broad color fields and start working with intricate patterns and sparkling accents that make your work uniquely yours.

Dichroic frit is essentially finely crushed dichroic glass, and it’s incredibly versatile. You can use it to create a sparkling, textured surface, sprinkle it into a mold for a specific pattern, or mix it with clear powder for a subtle, glittery effect. It comes in different grain sizes—from fine powder to coarse chunks—allowing you to control the level of detail. For example, you can use a fine dichroic frit to “paint” a delicate, shimmering design onto your base glass. It’s a great way to add intricate details without having to cut tiny, complicated shapes from a full sheet.

For creating crisp lines and defined borders, you’ll want to get familiar with dichroic glass stringers and noodles. Stringers are thin, spaghetti-like strands of glass, while noodles are flat, ribbon-like strips. Both are perfect for outlining shapes, “drawing” designs directly onto your glass, or creating geometric patterns. When you layer a dichroic stringer over a contrasting base color, it creates a stunning, high-impact line that really pops after firing. They offer a level of precision that’s difficult to achieve by cutting sheets, making them invaluable for detailed work.

Don’t forget about the creative potential of other unique forms like confetti and scrap packs. Dichroic confetti consists of tiny, thin shards of glass that you can scatter across a surface to create a random, sparkling effect, almost like glitter. And if you’re looking to experiment without committing to a full sheet, dichroic scrap packs are a fantastic, budget-friendly option. They give you a variety of colors, patterns, and textures to play with, making them perfect for small projects like jewelry or for adding a little extra flair to a larger piece. These smaller pieces are perfect for discovering new color combinations you might not have tried otherwise.

Choosing Your Texture and Finish

Beyond its color, dichroic glass comes with a variety of textures that can add incredible depth and dimension to your work. You can find it perfectly smooth or with patterns like ripples, waves, or geometric prisms pressed into the surface. A textured surface can break up the light in fascinating ways, creating a dynamic, sparkling effect that you wouldn’t get from a flat sheet.

You’ll also choose between transparent and opalescent base glass. Transparent dichroic glass is coated on a clear sheet, allowing light to pass through, which is perfect for layered designs. Opalescent dichroic glass is coated on an opaque base, usually black, which makes the dichroic colors appear incredibly vibrant and intense.

Examples of Popular Textures

Dichroic glass isn’t just about color; the texture on its surface plays a huge role in how it interacts with light. Exploring different textures can open up a whole new world of design possibilities for your fused glass art. Here are a few popular options you’ll come across.

Smooth: A perfectly smooth sheet of dichroic glass offers a sleek, modern look. It reflects light uniformly, which allows the pure, shifting colors to be the star of the show. This is a great choice for minimalist designs or when you want a clean, polished finish without any surface distractions.

Patterned: If you want to add more sparkle and movement, look for patterned dichroic glass. These sheets come with textures like ripples, waves, or geometric shapes pressed right into the surface. The patterns catch and scatter light in fascinating ways, creating a dynamic, glittering effect that adds a lot of depth and visual interest to your piece.

Etched: Etched dichroic glass provides a beautiful contrast between matte and shiny surfaces. The etching process creates a frosted finish on parts of the glass, which plays against the metallic shimmer of the dichroic coating. This creates a subtle, sophisticated look with a complex interplay of light. We carry a great selection of COE90 etched dichroic glass that’s perfect for adding this unique effect to your work.

Layering Textures: Don’t be afraid to mix and match! Combining different textures is a fantastic way to create one-of-a-kind designs. For example, you could layer a piece of smooth dichroic glass under a clear, textured cap glass. This adds dimension and complexity, giving your finished artwork a truly custom feel.

Finding the Perfect Color and Pattern

This is where you can really get creative. Dichroic glass is famous for its mesmerizing, color-shifting properties. A single piece can display a rainbow of hues depending on the viewing angle and how the light hits it. Some sheets are designed to shift between two specific colors, like cyan and magenta, while others offer a full spectrum.

On top of the color shifts, you can find dichroic glass with pre-made patterns on the coating. These can be simple dots and stripes or more intricate designs like swirls and mosaics. Combining different colors, patterns, and textures allows for endless artistic possibilities, whether you’re making a delicate pendant or a bold art piece.

How to Choose the Right Dichroic Glass

Walking into a glass supply shop or browsing online can feel like being a kid in a candy store, especially when you see all the shimmering dichroic glass. But with so many options, how do you pick the right one? Choosing the perfect dichroic sheet is about more than just finding a color you love. It’s about matching the glass to your project’s technical needs to ensure a beautiful, crack-free result.

Thinking through a few key details before you buy will save you time, money, and the heartache of a failed firing. By considering the glass compatibility, the final look you’re aiming for, and the technical aspects of your firing schedule, you can confidently select the best dichroic glass for your artwork. Let’s break down the four main things you need to consider to make the right choice every time.

Why Matching Your COE Is Crucial

If you’re new to glass fusing, the term COE (Coefficient of Expansion) is one of the first things you need to learn. It simply refers to the rate at which glass expands when heated and contracts when cooled. For a fused piece to be successful, all the glass you use must have the same COE. If you mix different COEs, the pieces will cool at different rates, causing stress and leading to cracks.

The two most common options you’ll find are COE90 and COE96. Neither is better than the other; they are just different systems. Make sure to choose the correct COE for your project, as all the glass in your piece needs to be compatible to fuse together properly. Always check the COE of your base glass and any accessory glass before you start.

Picking Glass for Your Specific Project

What are you planning to create? The answer will guide your choice of dichroic glass. Dichroic glass is incredibly versatile and can be used for everything from tiny, intricate jewelry pieces to large, decorative art panels. For delicate earrings or pendants, you might choose a glass with a fine, subtle pattern. For a statement bowl or a wall hanging, a bold, vibrant pattern might be more appropriate.

Think about the scale and function of your final piece. Will it be a flat panel or a slumped shape? Using different molds can transform a simple sheet of glass. Considering how the texture and color will interact with your design will help you select a sheet that truly complements your artistic vision.

Consider Firing Temperatures Before You Buy

Your kiln is where the magic happens, but an incorrect firing schedule can quickly turn a dream project into a disaster. Glass compatibility (COE) and firing schedules are closely linked. Different types of glass melt and anneal at different temperatures, so you need a schedule that’s right for the glass you’re using. Ignoring this is one of the most common mistakes that can ruin your art.

The final appearance of the dichroic coating can also shift depending on your firing temperature. It’s a great idea to keep a firing log to track your schedules, the glass you used, and the results. This will help you replicate successes and learn from any surprises. Understanding your kiln’s unique behavior is key to mastering dichroic glass.

Selecting the Right Thickness and Size

Dichroic glass sheets typically come in two standard thicknesses: 2 mm and 3 mm. A 3 mm sheet is sturdier and works well as a base layer or for a single-layer piece. The 2 mm thickness is a bit more delicate and is perfect for layering on top of other glass without adding too much bulk, making it a great choice for jewelry.

You should also think about the overall size of the sheet you need. Buying larger sheets can be more cost-effective if you have several projects in mind, as you can cut exactly what you need. However, if you’re just starting or working on a small piece, precut squares or scrap packs can be a fantastic way to experiment with different colors and textures without a big initial investment.

Common Sheet Sizes Available

Dichroic glass is available in a variety of sizes, making it easy to find just what you need for your project without overspending. For smaller pieces like pendants or for testing out a new color, you can often find precut squares as small as 3×3 or 4×4 inches, which are a budget-friendly way to experiment. For larger projects, you can purchase bigger sheets, sometimes up to 8×9 inches or more, giving you the freedom to cut custom shapes. If you’re stocking up your studio or planning a large-scale piece, it’s worth noting that many suppliers offer special pricing when you buy multiple full sheets at once. Exploring the different sizes available in our COE90 glass collection can give you a great sense of what will work best for your next creation.

Where to Buy Dichroic Glass Sheets

Once you’re ready to start a project, the big question is where to find the perfect glass. You have two main options: shopping online or visiting a local glass studio. Each has its own perks, and the right choice often depends on what you’re looking for. Online stores give you access to a massive inventory from the comfort of your home studio, while local shops offer a hands-on experience and a sense of community.

For many artists, a combination of both works best. You might rely on a trusted online retailer for your go-to supplies and larger orders, then pop into a local studio when you need a specific piece right away or want to see how the light hits a sheet of glass in person. Think about your project needs, your budget, and how you prefer to shop. There’s no wrong answer, and exploring different sources can even lead you to discover new and exciting types of dichroic glass you hadn’t considered before.

Online vs. Local: Where Should You Shop?

Online retailers like ArtGlassSupplies.com are fantastic for their sheer variety. You can browse an extensive selection of COE 90 and COE 96 dichroic glass, comparing different brands, patterns, and textures all in one place. It’s the most convenient way to stock up on supplies, especially if you don’t have a specialty store nearby. Local studios, on the other hand, offer the invaluable benefit of seeing the glass firsthand. Since the color-shifting properties of dichroic glass are notoriously difficult to capture in photos, being able to hold a piece up to the light can make all the difference. Plus, you get to connect with other local artists and get expert advice on the spot.

A Note on Color Accuracy Online

When you’re shopping for dichroic glass online, keep in mind that the pictures on the website might look a little different from the actual product you receive. The vibrant colors and shimmering effects can be challenging to capture accurately in photographs because the glass is so dynamic. A photo is just a single snapshot, but the real beauty of dichroic glass is how it changes in the light. Be prepared for some variation between what you see on your screen and the actual piece. While we do our best to provide true-to-life images, the way the light hits the glass in your own studio will always create a unique look.

Checking Stock Availability Before You Buy

Before you finalize your purchase, always check the availability of the products you want. It can be disappointing to plan an entire project around a specific sheet of glass, only to discover it’s out of stock. Knowing this in advance saves you time and frustration, allowing you to pivot your design if needed. At ArtGlassSupplies.com, we keep a vast inventory in our Goffstown, NH warehouse to get you what you need quickly. Still, some popular items can sell out fast. It’s a good practice to confirm stock levels before you check out, especially if you’re working on a tight deadline for a commission or a gift.

Budgeting for Your Glass Purchase

Budgeting for dichroic glass is pretty straightforward once you know what to look for. The price per sheet can vary quite a bit based on the brand, pattern complexity, and size. When shopping online, always factor in shipping costs. Some suppliers offer free shipping over a certain amount, so it can be more economical to place a larger order. If you’re just starting out or working on smaller pieces like jewelry, look for dichroic scrap packs. These are a wonderfully budget-friendly way to get a diverse assortment of colors and textures to experiment with without committing to full sheets. Planning ahead helps you get the most sparkle for your buck.

Example Pricing: What to Expect

Dichroic glass is a premium material, so you can expect it to be priced higher than standard sheet glass. However, there are plenty of affordable ways to get started. For instance, you can often find small, precut squares, which are perfect for jewelry or adding small accents to a larger piece. Prices for these can start around $16 for a 3×3 inch piece. Another fantastic option is a dichroic scrap pack. These bundles offer a variety of colors, textures, and patterns at a great value, with prices often beginning around $28. Scrap packs are an excellent way to build your collection and experiment with different styles without committing to full sheets.

Factoring in Shipping Costs

When you’re buying glass online, shipping is an important consideration. The cost can add up, but with a little planning, you can make it more manageable. Many online suppliers, including us at ArtGlassSupplies.com, offer free shipping once your order reaches a certain dollar amount. It’s a smart strategy to bundle your purchases. If you know you’ll need other supplies soon, like slumping molds or kiln wash, add them to your dichroic glass order to help you meet the free shipping threshold. This way, you save money on delivery fees and get all your materials for your next few projects at once.

Opportunities for Bulk Pricing

If you’re a professional artist or find yourself using a lot of dichroic glass, it’s worth looking into bulk pricing. Many suppliers offer discounts when you purchase a larger quantity, such as five or more full sheets of glass. These deals aren’t always advertised on the website, so it might require a little extra research. Don’t hesitate to check a supplier’s FAQ page or even call their customer service line to ask about discounts for volume purchases. Buying in bulk is one of the best ways to reduce your cost per project, especially if you have a go-to type of COE 90 glass that you use frequently in your work.

How to Prep and Handle Dichroic Glass

Working with dichroic glass is exciting, but its delicate metallic coating requires a little extra care. Proper preparation is the secret to making those incredible colors pop and ensuring your final piece is strong and beautiful. Before you even think about the kiln, taking a few key steps in handling, cleaning, and layering your glass will set you up for a successful fuse. Think of this prep work as the foundation of your project; getting it right makes the entire process smoother and helps you avoid common frustrations. Let’s walk through the essentials for getting your dichroic glass ready for the heat.

Tips for Cutting and Handling Safely

The dichroic coating is what gives the glass its magic, but it’s also fragile. When you’re cutting and arranging your pieces, handle them gently to avoid scratches. A great rule of thumb is to always place a layer of non-dichroic glass, like your base or a clear piece, between any two coated surfaces. This prevents the delicate coatings from grinding against each other. When you’re ready to cut, use a sharp, high-quality glass cutter and apply steady, even pressure. This will give you a clean score that breaks easily without chipping the special coating.

The Right Way to Clean Your Glass

It might seem like a small step, but cleaning your glass is one of the most important parts of the process. Dust, fingerprints, and oils can interfere with the fusing process, creating bubbles or a weak bond between layers. Skipping this step is a common mistake that can ruin an otherwise perfect piece. Before you assemble your project, wipe every piece of glass thoroughly with a lint-free cloth and isopropyl alcohol. Make sure the glass is completely dry before you start stacking your layers for the kiln. This simple habit ensures a clean, professional-looking result every time.

Why Capping Your Dichroic Glass Matters

Capping is the technique of placing a layer of clear glass over your dichroic glass before firing. This step is a game-changer for two reasons. First, it protects the delicate metallic coating from the intense heat of the kiln, which can sometimes degrade the finish. Second, the clear cap acts like a lens, giving your finished piece a smooth, glossy surface that makes the dichroic colors look incredibly deep and vibrant. While not every project requires it, capping your dichroic layer is the best way to get that stunning, high-quality finish.

Keep Metal Away From the Coated Surface

Here’s a key technical tip to remember: the metallic side of dichroic glass will not fuse to itself. If you stack two pieces of dichroic glass with their coated sides touching, they won’t bond together in the kiln. The metallic coating needs to fuse to a non-metallic glass surface. So, when you’re designing your piece, always make sure the coated side of your dichroic glass is facing the uncoated side of another piece of glass. This simple check will save you from the disappointment of opening your kiln to find your project hasn’t fused properly.

Tips for a Perfect Dichroic Glass Fusing

Firing is where the magic happens. It’s the final step that transforms your carefully cut pieces into a single, shimmering work of art. But getting it right requires a bit of know-how. The delicate metallic coating on dichroic glass behaves differently than standard fusible glass, so your approach in the kiln needs to be just right. A successful firing protects the vibrant coating, ensures a smooth finish, and prevents your project from cracking under pressure.

Don’t let the technical details intimidate you. With a little practice, you’ll learn how your specific kiln works and what your glass needs to fuse perfectly. We can break down the process into three key areas: establishing a reliable firing schedule, protecting the dichroic coating, and layering your glass for the best results. Mastering these steps will help you consistently create beautiful, professional-quality pieces that showcase the incredible depth and color of dichroic glass. Let’s get your project ready for the heat.

How to Create the Perfect Firing Schedule

Think of a firing schedule as a recipe for your kiln. It tells the kiln how fast to heat up, how long to hold at certain temperatures, and how slowly to cool down. Every project needs a carefully planned schedule to avoid thermal shock, which can cause cracks. The most critical rule is to ensure all glass in your project has the same COE. Mixing a COE 90 sheet with a COE 96 base will lead to cracking, as they expand and contract at different rates. An incorrect firing schedule can also cause your piece to warp or not fuse properly. Start with the glass manufacturer’s recommended schedule and adjust it based on your kiln’s performance and the size of your project.

Protecting the Dichroic Coating During Firing

The metallic coating that gives dichroic glass its sparkle is incredibly thin and needs protection during firing. The best way to do this is by “capping” it with a layer of clear glass. This technique not only shields the delicate coating from the intense heat of the kiln, which could cause it to burn away, but it also creates a smooth, glossy finish. A clear cap acts like a magnifying lens, enhancing the color and depth of the dichroic effect for a truly stunning result. This is a fundamental step for almost any dichroic project, especially if you want that polished, professional look in your finished piece.

Simple Rules for Layering Glass

How you stack your glass before firing has a big impact on the final shape and thickness of your piece. If you’re aiming for a full fuse where the glass melts completely together, a good rule of thumb is to use two layers of 3mm glass. For example, place a 3mm piece of dichroic glass on top of a 3mm piece of compatible base glass. This total thickness of 6mm helps the project hold its original shape and size without spreading out too much. Using just one thin layer will likely result in a piece that shrinks and becomes distorted. This two-layer method provides enough volume for a stable, even fuse, whether you’re creating jewelry or using molds to form a specific shape.

What Can You Make with Dichroic Glass?

Once you start working with dichroic glass, you’ll see possibilities everywhere. Its ability to shift colors makes it a showstopper in any project, big or small. Whether you’re looking to create wearable art or add a pop of color to your home, dichroic glass offers a unique creative path. If you’re wondering where to begin, here are a few ideas to get your imagination going.

Create Your Own Stunning Jewelry

Dichroic glass is a favorite among jewelry makers for a reason. Its dazzling, color-shifting properties are perfect for creating eye-catching pendants, earrings, and rings. Even the smallest scrap can be fused into a beautiful cabochon. You can start simply by layering a small piece of patterned dichroic glass over a solid-colored base and firing it in your kiln. Once your glass piece is fused and cooled, attach it to bails or earring posts to complete your creation. It’s a fantastic way to make personalized gifts or start your own line of custom jewelry.

Design Eye-Catching Art Panels

Take your art beyond the jewelry box by incorporating dichroic glass into decorative panels. The thin, multi-layer coating on the glass creates a stunning visual effect that can transform a simple design into a dynamic piece of art. Imagine a wall hanging that shimmers and changes color as you walk past, or a window panel that catches the sunlight. You can use dichroic glass as a focal point in a larger stained glass project or create an entire panel from different dichroic textures. It’s a wonderful way to play with light and add a touch of magic to any space.

Craft Unique Pieces for Your Home

Why stop at wall art? You can use dichroic glass to craft all sorts of unique home decor items. With so many colors and textures available, the options are nearly endless. Think about creating a set of vibrant coasters, a shimmering decorative bowl, or even custom cabinet knobs to add a personal touch to your kitchen. Using molds, you can slump and shape the glass into functional pieces that are also beautiful works of art. These projects let you express your creativity and result in items that will be conversation starters in your home.

Common Fusing Mistakes (and How to Avoid Them)

Working with dichroic glass is an incredibly rewarding process, but a few common slip-ups can turn a promising project into a frustrating learning experience. We’ve all been there. The good news is that these mistakes are easy to sidestep once you know what to look for. Paying attention to a few key details about compatibility, preparation, and firing will help you get beautiful, consistent results and save you from wasting precious materials. Let’s walk through the most frequent issues artists face and how you can steer clear of them.

Mistake #1: Mismatching Your Glass COE

One of the most critical rules in glass fusing is compatibility. Every piece of glass in your project must have the same Coefficient of Expansion (COE). This number tells you how much the glass will expand and contract when heated and cooled. If you mix glass with different COEs, like a piece of COE90 with a piece of COE96, they will cool at different rates. This creates stress within the piece, often causing it to crack or even shatter in the kiln or days later. Always double-check that every bit of glass, frit, and stringer you use shares the same COE to ensure your finished piece is strong and stable.

Mistake #2: Skipping the Cleaning and Prep

It might seem like a small step, but skipping a thorough cleaning can ruin your project. The surfaces of your glass sheets need to be perfectly clean before they go into the kiln. Dust, lint, fingerprints, and oils from your skin can get trapped between layers during fusing, creating bubbles and cloudy spots called devitrification. Before you assemble your piece, gently wash your glass with warm, soapy water or a dedicated glass cleaner, then rinse it well and dry it with a lint-free cloth. This simple habit ensures a flawless, professional-looking fusion every time and lets the true beauty of the dichroic glass shine through.

Mistake #3: Using the Wrong Firing Schedule

Firing glass isn’t a one-size-fits-all process. A firing schedule is the specific sequence of temperatures and holds your kiln follows to properly fuse the glass. Using the wrong schedule for dichroic glass can lead to a host of problems, from an incomplete fuse to unwanted textures or burned-out coatings. Different projects, glass thicknesses, and desired effects require different schedules. It’s essential to follow the manufacturer’s recommendations or use a schedule you’ve tested for your specific kiln and materials. Keeping a log of your firing schedules and results is a great way to perfect your technique over time.

Mistake #4: Placing the Coated Side Incorrectly

The dazzling effect of dichroic glass comes from its special metallic coating. A common mistake for beginners is placing two coated surfaces against each other. The dichroic coating will not fuse to another dichroic coating; it needs to fuse to a plain glass surface. If you stack two coated sides together, they simply won’t stick. To get that brilliant, colorful effect, always make sure the coated side of your dichroic glass is facing a non-coated glass surface, whether it’s the base glass or a clear cap. This ensures a solid bond and protects the delicate coating, locking in that signature shimmer.

How to Get Started with Dichroic Glass

This is where the fun really begins. You have your beautiful dichroic glass, and you’re ready to turn it into something amazing. Getting started is all about having the right tools, trying a few simple projects to build your confidence, and learning some key techniques along the way. Let’s walk through the first steps to get you creating with dichroic glass.

Your Must-Have Tools and Supplies

Before you can fuse, you’ll need a few key items. Your basic setup should include a glass cutter, running pliers, and safety glasses (don’t skip these!). Of course, you’ll need a kiln with a prepared shelf. For your glass, gather your dichroic sheets, a compatible base glass in a color you love, and some clear glass for capping. We carry a huge selection of both COE90 glass and COE96 glass to match whatever you’re working with. Finally, have some glass cleaner and lint-free cloths on hand, because clean glass is happy glass.

Easy First Projects for Beginners

The best way to learn is by doing, so start with something small and satisfying. Jewelry is a fantastic first project. Try cutting small pieces of dichroic glass and fusing them onto a black base to create stunning pendants or earrings. Ready for something with a bit more dimension? Make a small decorative dish. You can use a combination of transparent glass and CBS dichroic, tack fuse the pieces together first, and then slump the piece over one of our small molds in a second firing. You’ll have a beautiful, functional piece of art in no time.

Next Steps: How to Build Your Skills

As you grow, focus on the fundamentals. The most common issues in glass fusing come from ignoring glass compatibility (COE), not cleaning your glass properly, or using incorrect firing schedules in your kiln. A crucial rule for dichroic is to never place two coated surfaces together, as the metallic sides won’t fuse to each other. Always place a layer of non-dichroic glass between them. This is where capping comes in. Placing a layer of clear glass over your dichroic coating protects the delicate metallic surface and creates a smooth, glossy finish that really makes the colors pop. Keep a notebook of your projects and firing schedules to track what works.

Frequently Asked Questions

Is COE 90 better than COE 96 for dichroic glass projects? Neither one is better than the other; they are just different systems. The most important thing is that every piece of glass in a single project has the same COE, or Coefficient of Expansion. If you try to fuse a COE 90 piece with a COE 96 piece, they will shrink at different rates as they cool, which will cause stress and cracks. Many artists choose one COE to build their studio around to keep things simple and avoid any accidental mix-ups.

Do I always need to put a clear cap over my dichroic glass? While it’s not required for every single project, capping is a standard practice for a reason. Placing a clear layer of glass over the metallic coating protects it from the kiln’s intense heat, which can sometimes damage the finish. It also gives your final piece a smooth, glossy surface and makes the dichroic colors appear much deeper and more vibrant. For a professional, high-quality look, capping is almost always the best choice.

Why won’t my two pieces of dichroic glass fuse together? This is a common issue that comes down to how the glass is made. The shimmering side of dichroic glass has a metallic coating that will not fuse to another metallic coating. If you stack two pieces with their coated sides touching, they simply won’t bond in the kiln. To get a successful fuse, you must always place the coated side against a non-coated glass surface, like your base glass or a clear cap.

Should I use a black or clear base glass for my dichroic project? Your choice of base glass really depends on the look you want to achieve. A black, opaque base makes the reflective colors of the dichroic coating appear incredibly intense and dramatic because no light passes through it. A clear, transparent base is more versatile for layering, as it allows light to travel through the piece. This can create beautiful effects, especially if you have other colors or elements underneath the dichroic layer.

What’s the most affordable way to start experimenting with dichroic glass? If you’re just starting out and don’t want to invest in full sheets, dichroic scrap packs are your best friend. These packs contain a variety of smaller, assorted pieces of different colors, patterns, and textures. They are perfect for making jewelry or other small decorative items. Using scrap packs is a fantastic, budget-friendly way to learn how different types of dichroic glass behave in your kiln without a big upfront cost.
