Metal salts are created in an acid bath with 1 acid, 1 potash, 25 water in jugs and 7 of the appropriate metal.
Types of metal salts are:
So far as is known, the various alloys cannot be converted into metal salts.
When you begin the acid bath process, the acid eats away at the metal, producing a precipitate. The amount of precipitate increases over time, slowing as it goes (progress is shown). You may filter at any point to extract the salts.
