Glass Blowing: When you are working in the hot shop, you are working with the glass in its molten state (2100F). The process begins by taking a pipe and gathering molten glass from the furnace and then forming and shaping it with tools and by blowing air into it. You will be given the opportunity to apply color, reheat and shape your creation.

Flame Working: When you are working in the flame working studio, you are working with colored and clear glass rods or tubes in front of an open, gas-fueled torch. You will be given the opportunity to melt the glass as well as use tools and gravity to shape your item. SiNaCa Studios teaches with two different types of glass in our flame working studio. One is a soft soda-lime based glass that is used primarily for our bead making classes. The other is a hard glass called borosilicate, sometimes referred to as pyrex. It requires a much hotter flame to work, but can be used to create more complex sculptural and blown work.

Kiln Forming | Fusing & Slumping Glass: When you are working in the kiln forming studio, you are working with the glass in its solid state. You will be given the opportunity to cut and layer sheet glass with glass frit and stringers to create your design. We will then put the assembled work into an electric kiln where it will be fired over a 12-hour cycle to fuse the layers together. SiNaCa Studios uses and teaches with Bullseye Glass (90coe) exclusively in our kiln forming studio.
