Explore the limitless possibilities of sheet glass. Unlike furnace glassblowing or torch working which use molten glass, this studio works by cutting sheet glass allowing the artist to have more time to focus on color and design elements. The most common style of glasswork in this studio is kiln fusing and slumping but there are other forms of working with sheet glass such as stained glass, kiln casting, and mosaics.

This studio uses, and sells, COE 90 sheet glass. Projects made during classes may take up to 10 days before pickup. You must be age 12+ to register for classes listed below. Projects for ages 4+ can be found under our Make-Your-Own Experience page.
