Take your coldworking to the next level in this new and exciting coldworking class. Explore how traditional coldworking can be utilized in non-traditional and modern applications. 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.
