A “Novel” Project in Silver Clay

Saturday April 10 | 9am-12pm | Ed. Ctr. #1 | $100 Members | $115 General Public

This mini-book may not land you on the best seller’s list, but your friends will be clamoring at your door for their own personalized copy. Award-winning metal clay artist Lyle Rayfield guides participants through the process of creating and texturizing miniature book covers using silver metal clay, embellishing them with tiny clay elements and filling them with colorful pages or personalized notes or pictures. When complete, you will want to proudly wear your story for all to see. Microscopic particles of pure silver are combined with an organic binder to produce the clay-like substance known as silver metal clay. When fired at high temperatures, the binder burns off and the metal particles fuse into a solid piece of silver. Students will learn the a-b-c’s of working with fine silver metal clay while creating a mini-book inspired by the plants and animals of the Sonoran Desert. Demonstrations and instruction will cover how to properly roll, texture, shape, refine, fire, and finish metal clay creations (no experience necessary). All materials supplied, but please bring a magnifying glass and an apron.
