What is Smelting? (with pictures)

 · Although people often refer to smelting as another form of melting, simply melting material is not enough. The chemical reaction is necessary to force the desired ore to precipitate out, and it may be helpful to add a flux to bind with particulate materials, forming slag, a mass of unwanted material that will settle to the bottom of the furnace where people do their smelting.

What is the Melting Point of Gold? | Oxford Gold Group

Thankfully, gold''s melting point doesn''t change no matter how many other metals you throw in the mix. However, gold''s color, ductility, and hardness will vary depending on its alloy. Zinc and copper are much less ductile than gold, so if you''re planning to make gold leaves or other sheet-like ornaments, you''re better off with a 24-karat rock.
