Miller process amount of gold in the form of chloroauric acid which the Wohlwill process permanently requires for the electrolyte. Miller process The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.95%). It was invented by Francis Bowyer Miller ( patented 1867). This chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold. This process purifies the gold because nearly all other elements will form chlorides before gold does, and they can then be removed as salts that are insoluble in the
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."
