Fused glass is created by placing two or more pieces of stained glass in a kiln and heating them until they are fused together to create one piece. The slumped technique is performed by using a mold, placing the glass over it and placing both in the kiln. The glass is heated in the kiln until it slumps over the mold and creates a shape. In the cast technique the glass is placed into the kiln on top of a mold and heated until the stained glass fills the mold.
