Silver is a precious metal that has been mined for use as early as 4000 BC in Anatolia (Modern Turkey). [1] Because silver is malleable and durable it has been used for many purposes which include jewelry, tableware, ornaments, coins, musical instruments and movie film.
Gold jewelry is beautiful, durable and relatively easy to maintain. That said, not all gold is created equal and even the solid (i.e., not gold-plated) stuff requires an occasional polish. Without
Damascening is the art of inlaying different metals into one another—typically, gold or silver into a darkly oxidized steel background—to produce intricate patterns similar to niello. The English term comes from a perceived resemblance to the rich tapestry patterns of damask silk.

Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
Conservation treatments include dry cleaning, wet cleaning, consolidation and filling losses. Eastern cultures use Asian lacquer to repair damages and fill and consolidate losses. Western cultures typically use alternate materials that can be reversed with minimal risk to the original object.
Iron or carbon steel metal exfoliates when oxidized under neutral or alkaline micro-electrolytic conditions; i.e., the iron oxide (actually ferric hydroxide or hydrated iron oxide, also known as rust) forms by anoxic anodic pits and large cathodic surface, these pits concentrate anions such as sulfate and chloride accelerating the underlying ...
With some exceptions (e.g., platinum soldering in jewelry), the oxidizing flame is usually undesirable for welding and soldering, since, as its name suggests, it oxidizes the metal's surface. [2] The same principle is important in firing pottery.
