The lack of oxygen prevents tarnishing. They are then dropped into a quench tank filled with "slippery" water to quickly lower the temperature. The slippery water is a mix of water, citric acid powder, and lubricants that keep the blanks from sticking together. Next, a machine lifts the blanks out of the quench tank to drain.

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.

Producing Copper Nature's Way: Bioleaching
The "Gall-Copper Process" was recorded as being used during the Song Dynasty (960-1271AD). Copper was precipitated from solution by dipping iron into the blue vil solution - a process identified as early as 150 BC in China. 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date.
