Fused Glass Info

What is Fused Glass?

Fused glass is the process of creating a design with art glass and then firing it in a kiln to melt it into one large piece. The design can be made up of any form of glass as long as all of the pieces are the same COE. After melting the glass into a large sheet, sometimes the piece is placed over a mold (usually stainless steel or ceramic bisque) and allowed to slump into or drape over the mold. The molds must be coated with some kind of product to prevent the glass from sticking to the mold.

What is a COE?

Fusible glass must be fused with glass that has the same COE.
It stands for Coefficiency of Expansion, which is the rate that the glass expands when heated. If you fuse two different COE's in one piece, it may look okay, but it will break eventually because the piece is not stable.

The two main COE's are 90 and 96**. All Bullseye fusible glass is COE90. Uruboros and Wissmach make both COE90 and COE96.

There are basic kits available to get you started with glass fusing:
Glass Fusing Kits
These kits are relatively inexpensive and usually include a kiln that can be used in a microwave. It is recommended that you purchase a separate microwave to use for the kiln. Do NOT use kiln in the same microwave that you prepare food in.

After you try the kit and decide you want to pursue the hobby,
the links below take you to individual products that you may want
to add to your supplies.

**There is also a Float 82, and COE104 glass.
The Float 82 is used by some fusers,
The COE104 is usually used for making lampwork beads.

There are many books that have been written that will give you more information about glass fusing:
Glass Fusing Books
The books that I recommend are shown in the far right column on this page.
There are quite a few facebook groups that are for glass fusing. These groups show pictures of other members work and members can ask questions and answers are usually posted in a timely manner. They are:

There are also magazines for glass: Glass Magazines
What is FRIT?
Frit is the same as fused glass except it has been crushed. It also has different COE's. It comes in four different sizes.
They are:


COE90 Glass Frit    COE96 Glass Frit
Frit is used for many different techniques. I will explain some of them below.

Frit Painting
Frit painting is when you start with a sheet of fused glass (usually clear). It must be the same COE as the frit you will be using.

If you plan to use a mold, you should make sure the clear glass you are using is cut to the proper size to fit the mold.

Print out a design you like (not too detailed). Put the paper with the design under the clear glass.

Add frit on top of the clear glass layer, following the lines of the design. You should put enough frit that the clear glass layer will not be showing. When you have filled in the design, you can fire it to a full fuse.

When fired, if the colors seem too light, you can add more frit and re-fire.

After firing, the piece can be used as a sun-catcher panel or be slumped into a "prepared" mold to create a plate, bowl, platter etc.

Molds will be discussed separately.

Why do I need molds?
You don't actually need molds, but they can help you make many different items. There are slump molds and drape molds. Before using a mold it is necessary to coat it with kiln wash or Zyp spray on Boron Nitride.

Glass Molds

Slump Molds are used to allow the heated glass to fall into and take on the shape of the inside of the mold.

Drape molds are used to allow heated glass to fall over and take on the shape of the outside of the mold.

When you plan to use a mold, you should make sure the glass you are using is cut to the proper size to fit the mold, BEFORE doing any decorating or making designs.

What about a kiln?
There are several different brands of kilns and each brand makes several sizes and type of kilns.

Paragon Kilns      Jen-Ken Kilns

Initially, I would suggest buying a glass fusing kit that includes a microwave kiln and pick up a used microwave to fire in. Once you have done some small pieces with the microwave kiln, you will know whether or not you enjoy glass fusing.

At this point, the next step would be to sign up for a fusing class at a local glass studio. I recommend taking the class so that you can see what tools are needed and decide if you want to proceed with the hobby. It becomes a lot more expensive.

If you are considering buying a kiln, I would suggest that you visit your local glass studio and discuss it with the owners or teachers. You might want to read up on some of the types of kilns and their features before you visit the studio.
