Yazzie - Navajo Sterling Silver
Tufa cast, or sand cast, items are Indian Hand Made items using a procedure developed by the Navajo silversmiths in the mid 1800s. It is a labor-intensive process that involves many steps.
Using tuff stone, a porous rock from volcanic ash, tufa stone, a porous limestone that forms near hot springs, or sandstone, a harder stone, the artist carves the design of the item being cast. Another flat stone is placed against the carved half of the mold. The halves are fastened together and a sprue hole is carved into one end. Molten silver is poured into the mold using the sprue hole. Once the silver cools, the item is taken out and finished. Bracelets are poured flat and then shaped. Read more . . .
