Ending Saturday 11/14/2014: Native American Navajo .925 Sterling Sandcast Ring Size 7.5 Ken Charley Native American Navajo .925 Sterling Sandcast Ring Size 7.5 Ken Charley Traditional sandcast piece signed signed by Ken Chaley of Navajo Nation Arizona built to last for generations 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 Tufa Stone, a porous rock from volcanic ash, 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. Due to the porous nature of Tufa or Sand Stone, sandcast items will have character marks and imperfections such as small pits. That is the nature of Sand Casting and Indian Hand Made.
