Workshop Report: "Jewelry Narratives: Collecting to Casting" at Penland with Mary Hallam Pearse (June 10-22, 2018)
Mary Hallam Pearse's class, Jewelry Narratives: Collecting to Casting at the Penland School of Crafts, just wrapped up its first of two weeks. Mary was kind enough to send us some photos of what's been happening in her class in between casting 4 days in a row every morning for 3-4 hours and then doing demos each afternoon.
Class description:
This is what the center work table often looks like at a casting workshop - covered in molds, samples, cast objects, wax, and books. (Awwww... it's CAST... thanks, Mary!) Photos below will zoom in on parts of this table. Photo courtesy of Mary Hallam Pearse.
So far, the class has done plaster moldmaking, centrifugal casting, and induction vacuum casting. They've worked with carving wax, investment core casting to create hollow forms, patty cake silicone molds and water soluble wax for investment cores.

Mixing investment (high temperature plaster used for lost wax casting.) Investment molds go into a kiln, the wax is burned out leaving a cavity in the shape of the wax model, then molten metal is injected into the cavity using a centrifuge or vacuum casting machine.

It looks like the class has covered a lot of ground in the first week. Big thanks to Mary for taking the time to document and send us these process photos - we can't wait to see more pics next week!
