with Chris Ross

Calendar Next session starts Jun 15, 2026 at 9 am, runs for 1 week

Explore how traditional coldworking can be utilized in non-traditional and modern applications. Learn how to operate all of the equipment to cut, grind, drill, engrave, sandblast, and polish glass in this entirely cold process class. Learn techniques to strategize the best optical placement of cuts and gain experience using special adhesives to chemically bond glass segments together. Create unique works of glass art with interesting surface textures and shapes.

Collaborate with glass blowers in the hot shop to design colorful items then manipulate them to reveal layers of color with the lathe, sandblaster, or lap wheels. Combine found objects, cement, and glass. Then cut, laminate, and coldwork new and exciting shapes.  Leave with a foundational knowledge of coldworking techniques and understanding of the lamination process. Come away with new skills, fun projects, and inspiration for more complicated works.

Evening Open Studio Studios are open until 9:30PM for students to practice. Depending on the class, process, and techniques, this time might be highly suggested by instructors for students to use. In other classes, this time might be considered optional.

with František Janák

Calendar Next session starts Jun 29, 2026 at 9 am, runs for 1 week

With 60 years of experience and practice in the field of coldworking, František hopes to pass on the vast knowledge that he has acquired. He is coming from Czechia where coldworking has earned a long and strong tradition. In this class you will learn a step-by-step process to make a small glass sculpture from a solid block of glass and decorative, rich cutting to make patterns on blown vessel blanks. Together we will build a strong foundation for professional craftsmanship. The class will cover multiple approaches to shaping, sculpting, engraving, grinding, and polishing glass.

You will also learn how to assemble components using Ultraviolet Epoxy and properly set up and use different machines like horizontal flatting mill, vertical lathes, diamond saws, and belt sanders. With each machine there are specific and different grinding, smoothing, and polishing tools, materials, and processes. These tools include original Czech-made diamond, stone, and resin wheels. You will also be provided with information on how to design a perfect professional cold shop, including the necessary equipment.

No previous coldworking experience is required, although intermediate coldworkers are very welcome and may learn more than they have ever expected.

All students are welcome! Intermediate and advanced students will also be able to learn new skills and hone their existing skills.
