Low Tech Gravity Casting -IN STUDIO-
Instructor: Juan Reyes
July 24 and 25, Saturday and Sunday, 10:00 – 5:00
Class Fee: $425 | Basic materials included

Prerequisites: no experience necessary

Learn the fundamentals of casting by exploring the exciting and ancient technique of pouring molten metal directly into molds made from organic materials, sand and soft stone. This process does not require a centrifugal setup or any major equipment so it is easily reproduced in a home studio or in your back yard! This workshop will cover carving a mold and casting into tufa (light-weight sandstone), creating a quick mold in cuttlefish bone, a material easily found at any pet store producing a lovely texture, and sandcasting, an ancient way to reproduce an object. Students will also explore casting into other organic materials for surprising effects! Rudimentary alloying, pouring an ingot, finishing techniques and safety will all be discussed. Bring your clean silver scraps if you have some. No experience necessary.


Materials INCLUDED:

  • Tufa and cuttlefish bone to carve molds from
  • Sandcasting materials to use in class
  • 1oz. sterling silver
  • 1oz. casting bronze

Students MAY Bring:

  • A small object to mold that you think would be nice to reproduce in metal for jewelry like a shell or button.
  • Clean silver scrap (no solder on it!) or silver casting grain (available for purchase in studio store).
  • Dust mask
