Warm Glass is hot! Whether you currently do ceramics and are looking for something else to do with your kiln, or you are only interested in glass, we have information and supplies to get you started.

How do I choose a glass kiln?

Glass fires at a fairly low temperature (1400-1700 degrees), so just about all of our kilns will fire glass to some degree. But some are more specialized for specific processes. You can use a pyrometer, but it is much easier to use a kiln with an electronic controller. (You don't want one of the models that uses a kiln sitter.)

Can I fire glass in my ceramic kiln?

You can easily fire small pieces in a ceramic kiln. As you try to fuse larger pieces, such as plates and bowls, it becomes much easier when you have a lid element. All larger glass kilns have lid elements. Some newer kilns are designed for both ceramics and glass and have lid elements.

What can I make?

Many people start with small items such as jewelry, while they learn the techniques. Other commonly made items include glass tiles (fusing), plates, bowls, and vases (fusing and slumping), and glass beads (done with a flame but annealed in a kiln.)

Fusing is the melting together of different pieces of glass. Slumping is taking that glass and forming it into a shape using a mold. Casting is another area that can be simple (adding small glass chunks into a mold) or complex and very artistic (such as creating a sculpture out of clay, then creating a glass sculpture from it.)

How do I learn to do this?

An easy way to start is by buying one of our glass kits. Some even come with project instructions. We also sell some great books that walk you step by step through the process of making cool projects, and in the process teach you what you need to know about working with glass. These include Introduction to Glass Fusing, and the follow on book once you've mastered that: Fuse-It. Other books cover different techniques such as making beads and casting, but these two are excellent for beginners.

How much do I have to spend?

You can get a very nice set up for under $1000, including a kiln with electronic controller, glass and other supplies.

Slumping Wine Bottles

It has become very popular to slump wine bottles for bowls or cutting boards. Sometimes people paint them first with glass pigments. You can slump them on a shelf to make them flat, or use a mold to get a curved shape. Almost any kiln can be used to do this, but if that is your main purpose our TRIO KILN was designed for Bottle Slumping and Other Glass Fusing, Slumping and Casting. It works on any 120v household outlet. If you want to fire more than 2 bottles at a time, here are some other options

  • Paragon GL24ADTSD = 15 at a time
  • Olympic GF314E = 12 at a time
  • Olympic 1823FL = 5 or 6 at a time

We have some instructions for slumping wine bottles.

Note: COE's must match for a given project. (Do not mix COE90 glass and COE96 glass.)


Works like clay, fires as glass! Available in COE90 and COE96.
