The Way ...

Fused glass is the term used to describe glass that has been fired in a kiln at a range of 1100º F. to 1500º F. The heat will soften the glass causing it to become more fluid. This results in two or more pieces of glass “sticking” or fusing together.

The term full fuse refers to firing at the higher range of the spectrum of 1350º F. to 1500º. At this temperature, all of the pieces have completely melted together. Tack fusing occurs when glass is heated in the mid-range of 1250º F. to 1350º F. Some texture and depth is left behind when this is done. Slumping is the shaping and bending of glass commonly done while using a mold. The temperatures this occurs at are 1100º F. to 1250º F. All three of these techniques can be applied to one piece to add depth, relief and shape.

There is archaeological evidence that the first glass fusing was done by the Mesopotamians in 2000 BCE. By the second or third century AD fused glass techniques were virtually forgotten, replaced by the invention of the blowpipe and glassblowing. It wasn’t until the late 19th century that there was a resurgence in this art form.
