Kilnformed Glass

Before the Romans discovered how to blow glass, kilnforming was the technique used to shape glass. Because it consists of working with glass at temperatures below the full melting point of glass (glassblowing), yet warmer than cold glass (stained glass), it is often referred to as “warm glass” techniques. Kilnforming can be used to create 2 or 3-D pieces and includes fusing, slumping, carving and casting.

At GlassRoots, in our Kilnforming class, students learn to prepare a heat-resistant mold made of plaster or plaster mixtures. The mold is filled with solid glass granules or lumps and heated to between 800 - 1000°C. The glass melts within the mold, forming sculptures and other glass wares, custom pieces, or any creation the student wishes.

Students participating in our glass casting class learn how to pour hot molten glass into a preformed mold to create everything from tiles to bowls, dishes, cups, and much more.

GlassRoots teaches kilnforming to our students and also offers classes for the public.
