GLASS TYPES AND FORMS

beginning with a discussion of glass compatibility
There are many different production methods and recipes for making glass. As a result, there are almost as many different types of glass as there are glass artists who want to use them. Types of glass range from basic window glass (called "float glass") to brightly colored stained glass (also called "art glass"), and many of the types of glass come in numerous sub-types and categories.

In addition, there are many types of glass coatings, such as iridescent and dichroic, which have unique properties when applied to glass. New types of glass and glass coatings are constantly being developed.

All of these different glass types are candidates for fusing, slumping, and other warm glass processes. Some can be used off the shelf, but others require testing to make sure they will work in the kiln. That’s because it’s likely that you will want to combine more than one different sheet of glass in your projects. If so, then you’ll need to make sure the glass you select is "compatible." Using incompatible glass may cause cracking or even shattering of the piece when it cools.
UNDERSTANDING COMPATIBILITY

To better understand compatibility, let’s consider what happens when glass gets heated in a kiln. Like many other substances, glass expands when it gets hot and contracts when it cools. This change in density, which occurs at the molecular level, can be measured in a laboratory. A typical one inch piece of Bullseye brand glass, for example, will expand 0.0000090 inches for each 1 degree Centigrade (about 1.8 degrees Fahrenheit) increase in temperature. That’s nine-millionths of an inch!

This rate, which is commonly known as the Coefficient of Expansion (COE), is usually expressed as a whole number, rather than as a long decimal figure. Most Bullseye glass, for example, is said to have a Coefficient of Expansion of 90, and you will often hear glass artists refer to it as COE90 glass. Spectrum, another common glass, has a COE of around 96, while Corning’s Pyrex glassware has a 32 COE. Standard window glass, referred to as "float" glass by the glassmaking community, has a COE that is usually around 84-87, while Effetre (Moretti) glass, commonly used for lampworking, has a 104 COE.
