4703: Intro to Mosaics (Class 4703)

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.

Class 4704: Fused Glass Coral Bowls (Class 4704)

Diverse and beautifully mesmerizing, coral provides shelter and creates an environment to help marine life thrive. Inspired by the labyrinth-like patterns of coral found in our oceans, we invite you to make a fascinating interlocking glass design!
Students are provided with a variety of glass colors to choose from, as well as tools to cut and shape the pieces. As one carefully arranges the glass fragments, they can experiment with different patterns and arrangements to create a stunning coral-like design.

Class 4706: Strips’n’Bits (Class 4706)

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; prior experience with glass fusing is a good idea.
