CATALOGUE NOTES Gold & Tumbaga Gold Pre-Columbian gold has always been classified by the gold content. 80% or more gold in a piece is classified as pure gold. 60-80% as fine gold. 40-60% as poor gold. And, under 40% gold in a piece as Tumbaga. Tumbaga was the name given by Spaniards to a non-specific alloy of gold and copper which they found in widespread use in Pre-Columbian Mesoamerica. Tumbaga is an alloy comprised mostly of gold and copper. It has a significantly lower melting point than gold or copper alone. It is harder than copper, but maintains malleability after being pounded. Tumbaga can be treated with a simple acid, like citric acid, to dissolve copper off the surface. What remains is a shiny layer of 23-karat gold on top of a harder, more durable copper-gold alloy sheet. Use In The Americas Tumbaga was widely used by the Pre-Columbian cultures of central America to make religious objects. Like most gold alloys, Tumbaga was versatile and could be cast, drawn, hammered, gilded, soldered, welded, plated, hardened, annealed, polished, engraved, embossed, and inlaid. The proportion of gold to copper in artifacts varies wildly; items have been found with as much as 97% gold while others instead contain 97% copper. Some Tumbaga has also been found to be comprised of metals besides gold and copper, up to 18% of the total mass of the Tumbaga. Metalworking Repoussé or repoussage is a metalworking technique in which a malleable metal (such as gold leaf) is ornamented or shaped by hammering from the reverse side. Chasing is the opposite technique to repoussé, and the two are used in conjunction to create a finished piece. Whilst repoussé is used to work on the reverse of the metal to form a raised design on the front, chasing is used to refine the design on the front of the work by sinking the metal. The term chasing is derived from the noun "chase", which refers to a groove, furrow, channel or indentation. The adjective form is "chased work". The techniques of repoussé and chasing utilize the plasticity quality of metal, forming shapes by degrees. There is no loss of metal in the process, as it is stretched locally and the surface remains continuous. The process is relatively slow, but a maximum of form is achieved, with one continuous surface of sheet metal of essentially the same thickness. Direct contact of the tools used is usually visible in the result. Normal 0 21 false false false EN-GB X-NONE X-NONE
