Class 4804: Strips’n’Bits (Class 4804)

In two sessions, you’ll create a distinctive sushi plate using a unique pattern bar technique. Your choices along the way will explore the capacities of glass as a creative medium: Selecting colors—opaque, transparent, both? Cutting and layering shapes—bits and strips, irregular or not, deliberate or random? We’ll discuss the basics of firing schedules, safety procedures, and some of glass’s distinctive properties; work with glass cutting hand tools, chop saw, and belt sander; deal with serendipity; and keep your project together through multiple firings.

Class-size is limited; Intermediate level experience with glass fusing is a good idea.

4805: Intro to Mosaics (Class 4805)

Did you ever wonder about the mosaic art pieces you may have seen in archeological sites? Mosaics is one of the most beautiful and ancient ways to create art and express ideas. There are several materials that can be used to create mosaics. In this class, you will be able to learn different techniques to create your own mosaic art that will endure the passing of time. You will learn how to prepare a mosaic substrate, learn to cut glass, design and finish 2 plaques of 8 by 8 inches on your own.

Most of the work will be done on the first workshop day. The mosaic has to truly dry before applying grout, therefore, we will meet the next day to apply the grout and do final touches. Beginner level experience.
