Low Tech Gravity Casting
Instructor:  Juan Reyes
August 10 and 11, Saturday and Sunday, 10:30 - 5:00
Class Fee: $360 | Kit Fee: $60

Class format: in studio at Danaca Design

Prerequisites: None

Class Description:

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.

  • 3"x3" tufa stone block
  • 1 large or 2 smallish matching cuttle fish bone
  • 1oz ancient bronze casting grain

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, not too complex, 1/4" - 1"
