Think of it as a specialized, high-temperature oven designed specifically for glass. Its main job is to heat glass until it melts and fuses together or slumps into a shape. This process allows you to create everything from stunning jewelry and decorative tiles to beautiful plates and bowls.<\/p>\n<p>A quality <a href=\"https:\/\/www.artglasssupplies.com\/kilns\">kiln<\/a> gives you precise control over temperature, which is essential for working with glass. Whether you’re melting separate pieces into a single, smooth surface (fusing) or gently shaping a glass sheet over a form (slumping), the kiln is the heart of your glass art studio. It\u2019s the key piece of equipment that transforms your creative ideas and separate glass pieces into a finished, cohesive work of art.<\/p>\n<h3>How Do Fusing Kilns Work?<\/h3>\n<p>So, how does a kiln turn solid glass into a molten, workable material? It all comes down to controlled heat. Glass fusing kilns have heating elements, which are typically coils of wire that glow red hot when electricity passes through them. What makes these kilns special is <em>where<\/em> the elements are placed. Most have elements in the lid as well as the sides of the kiln body.<\/p>\n<p>This dual placement is crucial for even heating. As the glass heats up, the side elements warm the entire chamber, while the lid element radiates heat directly down onto the surface of your project. This top-down heat is especially important when the glass reaches its melting point, ensuring the entire piece heats uniformly and fuses properly without cracking from thermal shock.<\/p>\n<h3>Fusing Kilns vs. Pottery Kilns: What’s the Difference?<\/h3>\n<p>You might be wondering if you can just use a pottery kiln for glass, and it\u2019s a great question. While they both get incredibly hot, they are designed for very different jobs. The biggest difference is the heat source and chamber shape. Pottery kilns are typically deep, built for stacking multiple layers of ceramic pieces, and they usually only have heating elements on the sides.<\/p>\n<p>Glass kilns, on the other hand, are much shallower. Your glass projects are usually fired on a single shelf, often with <a href=\"https:\/\/www.artglasssupplies.com\/molds\">molds<\/a> to create shape, so you don’t need all that vertical space. More importantly, the heating elements in the lid provide the direct, even heat that glass needs to fuse flat. Using a pottery kiln for glass often results in uneven heating, where the edges get hotter than the center, which can ruin your piece.<\/p>\n<h2>A Look at the Different Types of Kilns<\/h2>\n<p>When you start shopping for a kiln, you’ll notice they come in a few main styles. Each design offers a different way to access your projects, and the right one for you really depends on the type of work you do and your studio space. Understanding the differences will help you find a kiln that fits your creative process perfectly. Let’s break down the three most common types: top-loading, front-loading, and clamshell.<\/p>\n<h3>Top-Loading Kilns<\/h3>\n<p>Top-loading kilns are exactly what they sound like: you load and unload your glass projects from the top. This design is incredibly common and versatile, available in everything from small tabletop models to large studio workhorses. Because you can easily lift the lid, it\u2019s simple to peek inside and check on your project during the firing cycle. This easy access makes them a favorite for artists who work with a variety of project sizes and want straightforward, reliable <a href=\"https:\/\/www.artglasssupplies.com\/kilns\">kilns<\/a> for their studio.<\/p>\n<h3>Front-Loading Kilns<\/h3>\n<p>Front-loading kilns open like a conventional oven, with a door on the front. This style is fantastic if you need to place items with a lot of precision, like when making jewelry or other small, detailed pieces. The front door gives you a clear, unobstructed view as you slide the shelf in and out, which helps prevent bumping delicate setups. This design is especially helpful for artists who create intricate work with <a href=\"https:\/\/www.artglasssupplies.com\/coe90\">COE90 glass<\/a> or have limited overhead space in their studio, making it easier to load and unload without reaching over hot walls.<\/p>\n<h3>Clamshell Kilns<\/h3>\n<p>Clamshell kilns offer a unique design where the entire top half of the kiln lifts up and away, giving you wide-open access to the chamber. This makes it incredibly easy to place large or complex projects without worrying about bumping the sides. Many clamshell models also have a removable floor, which is a game-changer for arranging glass pieces or setting up intricate <a href=\"https:\/\/www.artglasssupplies.com\/molds\">molds<\/a>. If you prioritize convenience and want the most accessible kiln interior possible, a clamshell design is an excellent choice for your glass fusing projects.<\/p>\n<h2>Key Features to Look for in a Glass Fusing Kiln<\/h2>\n<p>Choosing your first or next glass fusing kiln is a huge step, and it\u2019s about more than just price. The right kiln is an investment in your art, so it\u2019s important to understand the features that will help you achieve your creative vision. Think of it like buying a car; you\u2019re not just looking at the color, you\u2019re checking what\u2019s under the hood. Getting familiar with these key features will help you compare models and select a kiln that fits your space, budget, and artistic goals perfectly.<\/p>\n<h3>Size and Chamber Capacity<\/h3>\n<p>One of the first questions to ask yourself is, “What do I want to make?” The answer will guide you to the right kiln size. Kilns range from small, tabletop models perfect for making jewelry and coasters to large, professional studio kilns that can handle oversized platters and intricate sculptures. While it\u2019s tempting to start small, especially if you\u2019re on a budget, think about your future projects. Many artists recommend buying a slightly larger kiln than you think you need. This gives you room to grow without having to upgrade right away. Consider both the width and depth of the chamber, as this will determine the maximum size of your projects and the types of <a href=\"https:\/\/www.artglasssupplies.com\/molds\">molds<\/a> you can use.<\/p>\n<h3>Temperature Range and Control<\/h3>\n<p>For glass fusing, you need a kiln that can reach and maintain specific temperatures with precision. Most glass fusing happens between 1200\u00b0F and 1700\u00b0F, so nearly all glass <a href=\"https:\/\/www.artglasssupplies.com\/kilns\">kilns<\/a> are designed to operate comfortably in this range. While some models can reach higher temperatures, what\u2019s more important for glass art is not the absolute maximum temperature, but how well the kiln controls the heat. The ability to slowly ramp up, hold a specific temperature (or “soak”), and then cool down on a controlled schedule is what separates a successful firing from a cracked, disappointing mess. A reliable kiln gives you the control needed for consistent results every time.<\/p>\n<h3>Heating Element Design<\/h3>\n<p>Heating elements are the heart of your kiln, and their placement is a critical design feature. Look for kilns that have heating elements in both the lid and the body of the kiln. This design ensures your glass piece heats evenly from both the top and the bottom. Why does this matter so much? Even heating prevents thermal shock, which is when different parts of the glass heat or cool at different rates, causing stress and cracks. By distributing heat uniformly across the entire piece, top and side elements help you achieve a smooth, professional finish without frustrating imperfections, especially on larger projects.<\/p>\n<h3>Digital vs. Manual Controllers<\/h3>\n<p>The controller is the brain of your kiln, and this is where you\u2019ll see a major difference between older and modern models. Manual controllers require you to watch the kiln and adjust the temperature by hand throughout the entire firing process. Digital controllers, on the other hand, are a game-changer. You can program a precise firing schedule with multiple steps for ramping, soaking, and cooling, then simply press start. The kiln does all the work for you, ensuring your schedule is followed perfectly. For beginners and experienced artists alike, a digital controller offers peace of mind, repeatability, and the freedom to walk away while your kiln works its magic.<\/p>\n<h3>Energy Efficiency and Insulation<\/h3>\n<p>Let’s be practical: running a kiln uses electricity. Modern kilns are designed with energy efficiency in mind, using advanced insulation materials like high-density firebrick and ceramic fiber. This superior insulation does more than just help you save on your electricity bill. It allows the kiln to heat up more efficiently and, more importantly, hold its temperature with greater stability. A well-insulated kiln provides a more controlled environment for your glass, which contributes to better firing outcomes. When you\u2019re shopping, pay attention to the materials and construction, as a well-built, efficient kiln is a smarter long-term investment for your studio.<\/p>\n<h3>Essential Safety Features<\/h3>\n<p>Safety should always be your top priority when working with a kiln. Reputable manufacturers build several key safety features into their designs. One common feature is a lid or door safety switch, which automatically cuts power to the heating elements when the kiln is opened, protecting you from electrical shock. Another feature to look for is a “cool-touch” exterior. Some kilns are built with a layer of air between the inner chamber and the outer casing, which helps keep the outside of the kiln from getting dangerously hot. While these features are incredibly helpful, they don\u2019t replace the need for safe studio practices, like proper ventilation and keeping flammable materials far away.<\/p>\n<h2>An Introduction to Top Kiln Brands<\/h2>\n<p>When you start shopping for a glass fusing kiln, you\u2019ll quickly notice a few names that appear over and over. That\u2019s for a good reason. Brands like Evenheat, Jen-Ken, Paragon, and Skutt have built solid reputations in the glass art community by consistently delivering reliable, innovative, and well-crafted machines.

These <a href=\"https:\/\/www.artglasssupplies.com\/kilns\">versatile kilns<\/a> provide the space and control you need to take your work to the next level.<\/p>\n<h3>Professional-Grade Kilns<\/h3>\n<p>For the dedicated artist running a business or producing a high volume of work, a professional-grade kiln is essential. These kilns are built to be true studio workhorses, designed for durability and frequent use. You can expect to invest $3,000 or more, but in return, you get a massive firing chamber, advanced features like clamshell or front-loading designs, and powerful heating elements that ensure even firing for very large projects. These high-performance kilns are built to last and can handle the demands of a production environment, making them a reliable cornerstone for any professional glass studio.<\/p>\n<h2>Must-Have Accessories for Your Kiln<\/h2>\n<p>Your kiln is the heart of your glass studio, but the right accessories are what truly bring your creative visions to life. Think of your kiln as the oven and these accessories as your essential baking pans, racks, and parchment paper. They help you control the firing process, protect your equipment, and shape your glass into beautiful, finished pieces. Investing in a few key items from the start will save you a lot of headaches and open up a world of artistic possibilities.<\/p>\n<h3>Kiln Shelves and Posts<\/h3>\n<p>Kiln shelves and posts are the unsung heroes of a busy kiln. These sturdy supports act like a modular shelving system, allowing you to stack multiple layers of projects inside your kiln. This is incredibly useful for firing several smaller pieces at once, like jewelry or tiles, making the most of every firing. Posts come in various heights, giving you the flexibility to create the exact spacing you need for different project sizes. Using shelves and posts correctly ensures that heat circulates evenly around every piece, which is critical for a successful and consistent fuse.<\/p>\n<h3>Kiln Wash and Fiber Paper<\/h3>\n<p>Nothing is more frustrating than opening your kiln to find your beautiful glass project fused permanently to the shelf. This is where kiln wash and fiber paper come in. Kiln wash is a liquid separator that you paint onto your shelves, creating a protective barrier that prevents glass from sticking. It needs to be reapplied periodically. Fiber paper is a single-use alternative that you can place between your glass and the shelf. It\u2019s great for creating a super smooth bottom surface on your glass or for projects with intricate shapes. Using one of these is not optional; it\u2019s essential for protecting your <a href=\"https:\/\/www.artglasssupplies.com\/kilns\">kilns<\/a> and your artwork.<\/p>\n<h3>Molds for Slumping and Draping<\/h3>\n<p>If you want to create three-dimensional pieces like bowls, plates, or platters, you\u2019ll need molds. Glass slumping involves placing a piece of flat, fused glass over a concave mold and heating it until it softens, or “slumps,” into the mold’s shape. Draping is the opposite, where you place glass over a convex mold and let it melt down and around the form. There are countless <a href=\"https:\/\/www.artglasssupplies.com\/molds\">molds<\/a> available, from simple round bowl molds to more complex, sculptural shapes. They are one of the best ways to move beyond flat panels and start creating functional and artistic vessels.<\/p>\n<h3>A Note on Glass Compatibility: COE90 vs. COE96<\/h3>\n<p>When you start buying glass, you’ll see the term “COE” everywhere. This stands for Coefficient of Expansion, and it simply refers to how much glass expands and contracts when heated and cooled. It is absolutely critical that you only fuse glasses with the same COE together. Mixing different COEs will cause stress in the final piece, leading to cracks or even shattering. The two most common types you’ll work with are <a href=\"https:\/\/www.artglasssupplies.com\/coe90\">COE90<\/a> and <a href=\"https:\/\/www.artglasssupplies.com\/coe96\">COE96<\/a> glass. Pick one type to start with and make sure all your glass, frit, and stringers for a project match.<\/p>\n<h2>How to Choose the Right Kiln for You<\/h2>\n<p>Picking a kiln can feel like a huge decision, but it doesn’t have to be overwhelming. The best kiln for you really comes down to your personal goals, the space you have available, and your budget. Are you just starting out and want to experiment with small jewelry pieces? Or are you an experienced artist ready to create large, intricate wall art? Answering these questions will help you narrow down your options and find the perfect fit for your studio.<\/p>\n<p>Think about what you want to create now and what you might want to create in the future. While it\u2019s tempting to buy the biggest kiln you can afford, a smaller, more efficient kiln might be a better starting point. On the other hand, if you know you want to scale up quickly, investing in a larger model from the start could save you money in the long run. We have a wide variety of <a href=\"https:\/\/www.artglasssupplies.com\/kilns\">kilns<\/a> to match every ambition and workspace, so you can find one that feels like it was made just for you.<\/p>\n<h3>The Best Kilns for Beginners<\/h3>\n<p>If you’re new to glass fusing, convenience is key. Look for a kiln that is affordable and easy to set up. Many beginner-friendly <a href=\"https:\/\/www.artglasssupplies.com\/blog\/best-kiln-for-coe-90-glass\/\">kilns<\/a> are designed to plug into a standard 120V wall outlet, so you won\u2019t need to hire an electrician for special wiring. These models often feature heating elements in both the lid and the body, which helps your glass heat evenly and prevents thermal shock. A clamshell kiln is a fantastic choice for beginners because its top-opening design makes it simple to load and unload your projects without reaching into a hot chamber.<\/p>\n<h3>Kilns for Intermediate and Advanced Artists<\/h3>\n<p>As your skills grow, so will the size and complexity of your projects. Intermediate and advanced artists often need larger kilns to accommodate bigger pieces or to produce work more efficiently. A studio kiln is ideal for creating large-scale art, while a production kiln is built for firing multiple items at once, which is perfect if you’re selling your work. At this stage, you\u2019ll want to explore kilns from top brands like Evenheat, Jen-Ken, and Skutt. These manufacturers offer a range of sizes and advanced features to support more ambitious projects, including intricate slumping and draping with <a href=\"https:\/\/www.artglasssupplies.com\/molds\">molds<\/a>.<\/p>\n<h3>How to Find the Best Value<\/h3>\n<p>Finding the best value isn’t just about finding the lowest price; it’s about investing in a kiln that will serve you well for years to come. Before you buy, make a list of your must-have features, like chamber size and controller type. Keep an eye out for sales, as you can often find high-quality kilns with significant discounts. Remember that a reliable, well-built kiln is a long-term partner in your artistic journey. Taking the time to find the right one at a good price ensures you\u2019ll have a tool you can depend on as you continue to explore the beautiful world of glass art.<\/p>\n<h2>Common Mistakes to Avoid with Your First Kiln<\/h2>\n<p>Getting your first kiln is an exciting step, and you\u2019re probably eager to start creating beautiful fused glass art. While the process is incredibly rewarding, it does have a learning curve. I\u2019ve seen many new artists feel discouraged when their first few projects don\u2019t turn out as planned. The good news is that most initial problems come from a few common, and completely avoidable, mistakes.<\/p>\n<p>Think of your kiln as a powerful tool. Once you understand the basic rules, you can use it to achieve amazing results. It\u2019s not about being perfect from day one, but about building good habits that will set you up for success. We\u2019re going to walk through the most frequent missteps I see beginners make, from choosing the right glass to loading the kiln properly. By keeping these points in mind, you can skip a lot of the initial frustration and start making pieces you\u2019re proud of, right from the start.<\/p>\n<h3>Mixing Incompatible Glass<\/h3>\n<p>This is probably the most critical rule in glass fusing: you cannot mix different types of glass unless they are compatible. Glass expands when it gets hot and shrinks as it cools. The rate at which this happens is called the Coefficient of Expansion, or COE. If you try to fuse two pieces of glass with different COEs, they will shrink at different rates, creating stress that will cause your finished piece to crack or even shatter. It\u2019s a heartbreaking lesson to learn the hard way.<\/p>\n<p>To avoid this, always stick to one COE for a single project. The most common types for fusing are <a href=\"https:\/\/www.artglasssupplies.com\/coe90\">COE90<\/a> and <a href=\"https:\/\/www.artglasssupplies.com\/coe96\">COE96<\/a> glass. Neither is better than the other, but they are not compatible. Keep your glass organized and clearly labeled so you never mix them up by accident.<\/p>\n<h3>Skipping Kiln Wash<\/h3>\n<p>Think of kiln wash as the parchment paper of the glass fusing world. It\u2019s a liquid mixture that you paint onto your kiln shelf, creating a protective barrier between the shelf and your glass. When the glass melts, it wants to stick to whatever it\u2019s touching. Without that protective layer of kiln wash, your beautiful project will fuse directly to the shelf. This can ruin both your artwork and the expensive shelf itself.<\/p>\n<p>Applying a few thin, even coats of kiln wash before every firing is a non-negotiable step. It might seem like a small chore, but it will save you a massive headache and a lot of money in the long run. You can also use kiln shelf paper as an alternative for a perfectly smooth finish on the bottom of your piece.<\/p>\n<h3>Ignoring Firing Schedules<\/h3>\n<p>A firing schedule is your recipe for success. It\u2019s a detailed set of instructions that tells the kiln how hot to get, how fast to heat up, how long to hold a temperature, and how to cool down. Different projects require different schedules. For example, a full fuse (where glass melts into one smooth layer) needs a higher temperature than a tack fuse (where pieces just stick together). Ignoring the schedule is like baking a cake by just turning the oven on high and hoping for the best.<\/p>\n<p>Most modern <a href=\"https:\/\/www.artglasssupplies.com\/kilns\">kilns<\/a> have digital controllers that make it easy to program and save your favorite schedules. Take the time to research the right schedule for your specific project, glass type, and desired outcome. It\u2019s the key to getting consistent, predictable results.<\/p>\n<h3>Overloading the Kiln<\/h3>\n<p>When you\u2019re excited to fire new pieces, it\u2019s tempting to pack as much as you can into the kiln. However, overloading is a common mistake that leads to uneven heating and disappointing results. Your glass pieces need space for air to circulate around them. This ensures that every part of the project heats up and cools down at the same rate, which is essential for preventing thermal shock and stress cracks.<\/p>\n<p>As a general rule, leave at least one inch of space between your pieces and between the pieces and the kiln walls. You can use kiln shelves and posts to create multiple levels and use the space more efficiently, but the rule still applies. Giving your projects a little breathing room will make a huge difference in the quality of your finished work.<\/p>\n<h3>Forgetting Safety Precautions<\/h3>\n<p>Working with a kiln is safe, but you have to respect the tool. These machines reach incredibly high temperatures, and safety should always be your top priority. First, make sure your kiln is in a well-ventilated area, away from any flammable materials. Some glass can release fumes during firing, so good airflow is essential.<\/p>\n<p>Always wear the proper protective gear. This includes safety glasses to protect your eyes and heat-resistant gloves for handling kiln parts or shelves, even after they\u2019ve had some time to cool. Never look directly into the kiln through a peephole without specialized glasses, as the bright light can damage your eyes. Following these simple guidelines will ensure your glass fusing journey is a safe and enjoyable one.<\/p>\n<h3>Not Keeping a Firing Log<\/h3>\n<p>A firing log is one of the most powerful learning tools you can have. It\u2019s essentially a diary of your kiln firings. For each project, you should write down what type of glass you used, the firing schedule you ran, where the piece was placed in the kiln, and what the final result looked like. Taking a quick photo to go with your notes is even better.<\/p>\n<p>This practice might seem tedious at first, but it will become invaluable. When a piece turns out perfectly, your log will tell you exactly how to replicate it. When something goes wrong, your notes will help you troubleshoot the problem. Over time, your firing log will become your personal encyclopedia of glass fusing, helping you refine your techniques and become a more confident artist with every firing.<\/p>\n<h2>Keeping Your Kiln in Top Shape<\/h2>\n<p>Your kiln is one of the biggest investments you’ll make in your glass art journey, so it’s worth taking care of. Think of it like any other essential tool in your studio. A little bit of regular maintenance will keep it running smoothly for years, ensuring your projects fire predictably and safely. Neglecting your kiln can lead to inconsistent results, failed firings, and even costly repairs. By building a few simple habits, you can protect your kiln and focus on what you love most: creating beautiful glass art. Let’s walk through the three key areas of kiln maintenance.<\/p>\n<h3>Regular Cleaning and Inspection<\/h3>\n<p>Keeping your kiln clean is one of the easiest ways to ensure its longevity and performance. After each firing, once the kiln has completely cooled, take a moment to vacuum out any dust or small debris. Glass dust and bits of kiln wash can build up over time, potentially contaminating future projects or affecting how evenly your kiln heats. While you’re cleaning, do a quick visual inspection. Check the brick for any new cracks, and examine your kiln shelves and posts for wear and tear. Catching small issues early can prevent them from turning into bigger problems down the road.<\/p>\n<h3>When to Check and Replace Heating Elements<\/h3>\n<p>The heating elements are the heart of your kiln, doing the hard work of bringing your glass up to temperature. Over time, they will naturally wear out. You should get into the habit of inspecting them regularly. Look for any signs of wear, like sagging, discoloration, or visible breaks in the coils. Another telltale sign is a change in performance. If you notice your kiln is taking much longer than usual to reach its target temperature or your firings are uneven, it might be time for a replacement. Learning to understand kiln elements and their condition will help you avoid a surprise failure mid-firing.<\/p>\n<h3>Calibrating Your Temperature Controller<\/h3>\n<p>For consistent and repeatable results, you need to trust that the temperature on your controller is the actual temperature inside your kiln. Over time, the thermocouple that reads the temperature can degrade, causing the readings to drift. It\u2019s a good practice to calibrate your controller at least once a year, or anytime you feel your firing results are not what you expect. Calibration involves comparing your controller’s reading to an independent, accurate pyrometer. This simple check ensures your carefully planned firing schedules produce the beautiful results you’re aiming for.

Many smaller, entry-level kilns are designed to plug directly into a standard 120-volt household outlet, which makes getting started very simple. However, most mid-range and professional kilns require more power and need a dedicated 240-volt circuit, similar to an electric stove or dryer. Always check the specific electrical requirements for the model you’re interested in, and plan to hire a qualified electrician for any necessary installation.<\/p>\n<p><strong>What’s a good first project to make in my new kiln?<\/strong> I always suggest starting with something small and flat. Making a set of simple coasters or a few suncatchers is a perfect first project. This allows you to get a feel for how your glass cuts, how it behaves at fusing temperatures, and how your specific kiln fires without the added complexity of a mold. You’ll learn a lot about your firing schedule and materials, which will build your confidence for more ambitious projects like bowls and plates.<\/p>\n<p><strong>Can I ever mix COE90 and COE96 glass in the same project?<\/strong> The short and simple answer is no. It’s the most important rule in glass fusing. COE refers to how much the glass expands and contracts with heat. Even though the difference between 90 and 96 seems small, it’s enough to create immense stress as the piece cools. Fusing incompatible glasses will almost always cause your finished artwork to crack, sometimes hours or even days after it comes out of the kiln. Always keep your glass types separate and clearly labeled.<\/p>\n<p><strong>Should I start with a small kiln or invest in a larger one right away?<\/strong> This is a great question that comes down to balancing your budget with your artistic goals. A small kiln is more affordable and perfect for learning the basics with jewelry or small tiles. However, many artists find they quickly want to make larger items. If you have a strong feeling you’ll want to create plates, platters, or larger art panels, investing in a slightly bigger kiln than you think you need now can save you from having to upgrade later.<\/p>\n<p><strong>Where is the best place to set up my kiln?<\/strong> Safety and ventilation are your top priorities. The ideal spot is a well-ventilated area like a garage, basement, or dedicated studio space with good airflow. Never operate your kiln in your main living area. You must place it on a non-combustible surface (like concrete or a specialized kiln stand) and ensure there are at least 18 inches of clear space around all sides of the kiln, away from any flammable materials like curtains, paper, or wood.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Find out how to choose the best glass fusing kiln, compare top brands, and get tips for safe, successful glass art projects in this complete guide.<\/p>\n","protected":false},"author":5,"featured_media":1640,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-1641","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\/1641","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=1641"}],"version-history":[{"count":0,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/posts\/1641\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/media\/1640"}],"wp:attachment":[{"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/media?parent=1641"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/categories?post=1641"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.artglasssupplies.com\/blog\/wp-json\/wp\/v2\/tags?post=1641"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
