As you may already know Tufa Casting is a very laborious and even dangerous process of making silver jewelry that was developed late in the 19th century by the Navajo. It is similar to traditional sand casting but uses ancient compressed volcanic ash (Tufa) as the mold in which hot molten Silver is poured. Because of thermal shock it is typical that the Tufa mold can only be used once.
After the piece is cooled, the "real work" of filing and polishing begins. Because of the factors mentioned, Navajo Tufa Cast Jewelry is relatively rare and becoming more so all the time. The technique lends a charm to anything produced and is appreciated by knowledgeable collectors of Native Jewelry.
In the 1959 publication "Indian Silverwork Of The Southwest, Illustrated" author Harry P Mera has provided us with the definitive guide to the origins, history, and techniques used by Native American jewelers. Later on, when, through experience, easily worked fine-grained stones were selected (those capable of retaining clean cut impressions) ornamental casting finally came into its own. Materials of this sort, because of their friability, are apt to break down under the heat to which they are subjected so that, at best, a very limited number of castings could be made from and average mold, often, only one. After an object is cast, a great deal of work with files and other abrasives is required to obtain a satisfactory finish.
" Indeed, the "clean up and finishing of the crude Sterling Silver article after is it liberated from the Tufa mold is an enormous and messy task! The design of the Tufa Cast Silver work as seen in the buckle is what most collectors would generally call Classical Revival. This is a beautiful Belt Buckle that demonstrates the art of the Tufa Casting technique. I hope you are pleased with what you see.. As the Navajo say, "Walk in Beauty".I thank You and look forward to sharing a good experience! "AMERICAN INDIAN JEWELRY I" - Gregory Schaaf - Page. "AMERICAN INDIAN JEWELRY II: A-L" - Page.
