Silver processing

Silver processing - Refining, Alloying, Uses: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.

The Ancient Origins of Silver Mining and Refining

The origins of rudimentary poured silver bars can also be traced to this period. The use of silver in these primitive ancient societies allowed them to thrive, laying the groundwork for future civilizations. Another notable era of silver mining occurred around 1,200 BC in the "Mines of Laurion" on Greece's Attica peninsula near Athens.
