Glass casting has a number of different methods and I've been exploring them with students. The two pieces featured here were created by Becky Casady in a recent class. The first was designed with fiber paper carved and laid on the kiln shelf where glass was placed over it. The second piece was created with a clay model and then a cast was poured. Once the cast set, the clay model is removed and replaced with cullet (chunk glass) and fired in the kiln until molten. The cast is easily removed from the glass by breaking it away; the original cast cannot be reused.
