Lost wax kilncasting is a versatile method for making glass pieces in almost any form imaginable. The process involves creating a refractory mold around a wax model. The wax is then removed—or "lost"—creating a cavity. Glass is cast into the cavity, resulting in a fully sculptural finished piece.

In this lesson you will learn how to prepare a wax model, how to make a two-layered refractory mold, and how to steam the wax out of the mold. We'll also cover how to calculate the amount of glass needed, prepare the kiln for firing, and cast the glass into the mold. Finally, we'll discuss how to successfully cool and clean the resulting piece.
