Tufa casting, a technique using a compressed volcanic ash material found on the Navajo reservation called tufa stone, is a renowned, traditional form of jewelry creation. With two halves rubbed together to create a perfectly flush surface, silver or gold is poured into cone shaped holes known as sprue holes that fill the mold created by the tufa stones. Carbonized with a torch and with both halves bound together, the desired metal is poured in and allowed to cool, with the hardened piece of metal then taken out of the mold. The artist then carefully sands and cleans the design, shaping the flat metal into its beautiful final form. With most tufa molds breaking after a single cast, these pieces of tufa-cast jewelry are a one-of-a-kind work of art with the beauty of the porous and unique texture provided by the tufa stone mold seen all through out these wholly original and unique pieces.
