Fused and Kiln Formed glass are general terms used to describe glass that has been formed, manipulated and shaped in a glass kiln... Fused glass is similar to baking glass. Glass pieces are cut and arranged by hand, then slowly heated in a kiln over a period of several hours. At temperatures between 1400 and 1500 degrees F (760 - 840 degrees C), glass softens to a honey-like consistency and the separate pieces of glass liquefy and fuse together into a single piece of glass. When the glass has reached the state desired by the artist, the kiln is shut off, and annealing begins. Annealing is the slow cooling of the glass to prevent the presence of internal stress (which can lead to bubbles, cracks, or fractures).
