The 14 Best Kilns for Glass Fusing

Are you interested in becoming a glass artist and want to learn how to fuse glass at home? Setting up a home workshop is an exciting step for hobbyists who want to get better at their craft, and getting a suitable glass kiln is an integral part of this process. 

There are so many choices when it comes to glass fusing kilns that it can be hard to know where to start. We've put together a complete guide with all the essential things you should think about to make your search easier and make sure you make the right choice. Besides these things to think about, we've also put together a list of our top glass kiln picks to help you narrow down your options and find the perfect kiln that fits both your artistic vision and your practical needs.

Some Things to Consider Before Buying a Glass Fusing Kiln

When buying a glass-fusing kiln, it’s a good idea to have features and specifics in mind for your kiln. Whether you’re looking for a beginner kiln or you’ve been in the game for a while, here's a breakdown of what you should consider when buying: 

Temperature and Heat Distribution

Firing glass in kilns is a delicate process, as it rarely exceeds 1699°F due to its low-fire nature. Achieving even heat distribution is crucial for successful fused glass projects, especially given glass's vulnerable molecular structure due to expansion and contraction.

While you can use a ceramic kiln for glass projects, it's essential to note the differences. Ceramics kilns typically have side elements only, whereas glass kilns are designed to radiate heat from both the sides and the top. This design feature helps mitigate glass's sensitivity to temperature fluctuations.

If you're concerned about even heat distribution, opt for a shallower kiln. The depth of the kiln can impact how evenly heat is distributed during firing. Understanding the temperature ranges for different glass procedures is also crucial. Slumping occurs between 1215-1249°F, tack fusing between 1350-1369°F, contour fuse around 1400-1450°F, full fuse between 1450-1479°F., and glass casting happens between 1550F-1675F. A quality glass kiln should be capable of reaching and sustaining these temperatures. 

Consider your firing needs when choosing a kiln controller. If you plan to use various firing programs, ensure the controller can accommodate your requirements effectively.

What Should You Ask Yourself Before Glass Fusing? 

When purchasing a kiln, it's crucial to consider various factors related to your artistic endeavors and the available workspace. Here are key questions to guide your decision-making process:

What Kind of Projects Will You Be Working On?

Consider your glass fusing projects' size and complexity when choosing a kiln, ensuring it fits your studio space and budget. Look for features like programmable controls, safety mechanisms, and upgraded relays. Check the kiln's power requirements and brand reputation, keeping future expansion in mind for a seamless glass fusing experience.

Glass, being a low-fire material, doesn't vary much in terms of temperature maximums across different kiln models. However, the specific kiln temperatures and firing schedules you'll need depend on factors like the type of project (tack fusing versus full fusing) and techniques used. It's crucial to consider not just the size of your pieces and their temperature requirements but also how well your kiln’s controller can handle and maintain various programs and temperature adjustments effortlessly. This ensures smoother and more precise glass fusing processes tailored to your artistic needs.

How Much Electrical Power Do You Have Available?

When selecting a kiln, consider the energy consumption based on its size. It's important to match the voltage and amperage requirements of the kiln to the available power supply in your workspace. Opting for a kiln with higher energy needs may require an additional investment in electrical upgrades to ensure it functions efficiently and safely.

Electricity and Voltage Requirements

Considering voltage and amperage is crucial when choosing a kiln. The typical household voltage is 120 volts, suitable for smaller kilns. However, larger kilns often need 240 volts, requiring appropriate wiring and receptacles for safe operation.

Ensure your breaker meets the kiln's amperage needs. Check your fuse/breaker box for available amperage availability. Even with the correct voltage, insufficient amperage will prevent a kiln from operating correctly. 


The rules of physics dictate that a certain amount of energy is required to heat a particular amount of space. What this means is that at a certain kiln size, usually about 15”, a kiln will require more power to function. So…as a general rule, kilns over 15” in size are almost always powered by higher voltage, as they need more amperage to operate.

 With all of that said, here is the common sense decision-making equation: If I want bigger than 15” in size (13" shelf) - then you must commit to 240v power. If you only have 120v power available - then you must stay under 15” in size. This has no bearing on the shape of the kiln you choose, although the depth will play a part in determining the volume of chamber space that needs to be heated.

Once you know you can “feed” the kiln with the proper electrical configuration, selecting the size should align with your project needs and available workspace. Although larger kilns are slower to heat up and cool down, they can fire larger pieces but may limit daily firing. Smaller kilns, ideal for beads, jewelry, and small items, offer quicker cycles and more versatility.

Efficiency peaks when firing a full kiln, so factor in not just the size of your projects but also how long it takes to fill the kiln for optimal use.

Where Are You Placing the Kiln? 

Location considerations extend beyond kiln size and electrical requirements; they also influence kiln features you might need. In a busy setting like a studio, ventilation is crucial. Place your kiln near a window and opt for models that don't crowd your space. However, ventilation becomes less of a concern if your kiln is in a less populated area like a garage.

Height is another factor based on your chosen location. Top-loading kilns are standard for small glass fusing kilns, so ensure the kiln's height, combined with its stand, allows for comfortable loading at waist level.

Which Controller Do You Need?

Kiln Frog offers various kiln control options, each with its benefits. Manual controllers are not appropriate for glass projects as they require constant monitoring and adjusting to accomplish more rigorous glass firing schedules. Digital controllers are much more user-friendly. The electronic controllers provide up to twelve firing programs and have room for customized user input, while the Digital Touchscreen controllers like TAP, Genesis, and Spark controllers offer touchscreen customization and wifi connectivity for program monitoring and editing from different devices. These controllers all work well for beginning hobbyists or seasoned professionals.

Accessories and Kiln Furniture

Kiln Shelves: Firing on a properly treated, elevated kiln shelf with posts is a requirement for all glass firings to ensure proper heat penetration and distribution. When purchasing a kiln, bundling furniture accessories will reduce shipping costs and enhance your firing experience. High-quality shelves keep kiln floor grain off your pieces, creating a smooth firing surface. Second, kiln shelves safeguard the kiln's interior from firing accidents by separating hot glass from floor bricks. This extra protection can help your kiln last longer and work better. 

Kiln Posts: Kiln posts play a crucial role in kiln firing by raising shelves above the kiln floor, offering support, and maximizing the airflow in the kiln around the glass pieces being fired. They come in various thicknesses and heights, providing flexibility to accommodate different kiln configurations and firing needs.

Furniture Kits: A convenient solution to the dilemma of selecting shelves, posts, bricks, and materials for your kiln is to opt for a furniture kit, available with many kilns from Kilnfrog. These kits streamline the process by bundling the most crucial accessories into a single purchase, saving you time and effort in sourcing individual items.
