Fusing!
Fused glass is the process of melting several layer of glass together in a kiln. However, that doesn’t mean just any glass thrown into a kiln. Glass that is melted to another has to have the same rate of expansion and contraction, also known as COE. This prevents stress in the glass that may cause the piece to crack or break.There are 4 main distinction of temperature applications for melting glass.Slumping: is the description for heating the glass to the point it softens enough to bend. Most any single layer of glass can be slumped. It most often is done over or into a mold. Slumping occurs between the temperatures of 1200 degrees to 1300 degrees.

Tack Fuse: is the term to describe heating 2 or more layers of glass to the point they stick together but not change their shape. This usually occurs between the temperature between the temperatures of 1300 degrees to 1400 degrees.
Contour Fuse: is the process at which the tack fuse pieces begin to change their shape but remain 2 distinct layers. This will happen between the temperatures of 1400 degrees and 1475 degrees.
Full Fuse: this is the description given to the process of heating several layers of glass to the point they become fully laminated to one layer. The layers will want to be about ¼ of an inch thick so 3 or more layers will spread out larger than original shape. A single layer will shrink from the original shape. A full fuse will occur between the temperature of 1450 degrees and 1550 degrees
Temperatures stated above are just a guideline. Your temperatures may vary depending on the size and thickness of you project and your kiln. Fusing glass is fun and we can take the mystery out it with our classes. No previous glass skills are needed to melt a 4 inch tile or 4 cabochons that can be made into glass pendants. This is a great single class for the family or group of friends. Call 386-738-1008 and let us know what you're interested in or e-mail us at sales@glassicarts.net |
