How long does it take to fuse glass?
Most fusing glass will fuse between 1450 F and 1480 F. It is possible to get the same results (or the same amount of heatwork), by bringing the kiln to 1450 F and holding it at that temperature for 30 minutes as you would by bringing the kiln to 1480 F and holding it for only 10 minutes.
Can You fuse glass in a kiln?
As a matter of fact you can. For years it was believed that glass could only be fused in a kiln with elements in the lid. Artists worried that if you tried to fuse glass in a side-fired kiln the temperature difference between the edges of the glass near the elements, and the center of the glass would become to great and the piece would crack.
When do you need a glass kiln?
The simple answer is we need to use a kiln when we want to fuse, slump, polish, mold, and melt glass. The most common usage of kilns is for fusing and slumping. Glass Kilns are of many types such as microwave glass kilns, electric kilns, stainless steel kilns, ceramic kilns, craft kilns, traditional kilns, and professional glass fusing kilns.
How long does it take to make a firing glass lamp?
Depending on the glass and the size and thickness of the project, it can take anywhere from three to four hours for smaller pieces, and up to 13-14 hours for larger pieces.

What is the difference between slumping and fusing glass?
Difference between slumping vs fusing Glass slumping is a different technique than fusing. Glass fusing focuses on combining glasses into one piece with high or low temperatures, on the other hand slumping is more focused on re-shaping glass into a new version with a help of mold in a kiln.

There are a number of online resources, but taking an in-person class is ultimately the best way to learn. Taking a glass fusing class with the guidance of an experienced glass artist is necessary, both for your safety and to create the highest quality work. Keep in mind that when you are first starting out, an in-person class will be less costly than setting up a proper glass fusing studio at home. Due to the high costs of setting up your own studio, starting by taking an in-person class is recommended.

What to do if glass breaks in kiln?
If your glass breaks in the kiln, your project didn't turn out quite as expected, or you feel the need to add further embellishments to your project, you can re-fire your project until you get the results you desire. For cracked glass some artists add additional pieces of glass to the top of the glass to reinforce and cover the "seam" where the crack occurred. Do not try to re-fire projects with incompatible COEs. Even if the project survives the heating and cooling process the stress remains and the piece can crack or break later.

It's important that all of the glass you are fus ing together expands and contracts at the same rate or stress and cracking can occur. Glass manufactured specifically for fusing is tested for compatibility. Always fuse glass with the same COE or tested compatible glass.
What is the process of annealing glass?
Slow, controlled cooling, commonly referred to as annealing, is the process in which you allow the glass to gradually cool down in order to remove internal stresses that may have occurred during the firing process. Annealing allows the glass to stabilize and adds strength to your finished project.
How thick is a sheet of glass?
A standard sheet of glass is approximately 1/8" thick. When firing a single layer of glass the edges will contract to become ¼" thick. If fusing three layers of glass your glass will expand to become ¼" thick. Unless you are damming the glass, two layers are ideal to maintain your projects original size and general shape.

The Coefficient of Expansion (COE) refers to the rate at which glass expands and contracts when heated and cooled. All glass has a COE but we don't always know what it is. It's important that all of the glass you are fusing together expands and contracts at the same rate or stress and cracking can occur. Glass manufactured specifically for fusing is tested for compatibility. Always fuse glass with the same COE or tested compatible glass.
