Wohlwill process Wohlwill process The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). The process was invented in 1874 by Emil Wohlwill. This electrochemical process involves using a cast gold ingot, often called a Doré bar, of 95%+ gold to serve as an anode. Lower percentages of gold in the anode will interfere with the reaction, especially when the contaminating metal is silver or one of the platinum group elements. The cathode(s) for this reaction are small sheets of pure (24k) gold sheeting or stainless steel. Current is applied to the system,
Commodity pathway diversion inherent market value. They reacted against this perceived commoditization of art by producing what they considered decommodified art. However, as Kopytoff argued, "commodities must be not only produced materially as things, but also culturally marked as being a certain kind of thing." Thus, when diverting industrial materials from their commodity pathways to produce art became culturally valuable, the objects themselves gained value (1985). Finally, pop artist Andy Warhol, created artwork couched in what Appadurai refers to as the "aesthetics of decontextualization." In his famous Campbell's Soup painting, Warhol diverts advertising from its commodity pathway by reproducing it as a work
