Regarding this, how do you remove borax from silver?

Combine 1 teaspoon to 1/4 cup of borax into enough boiling water to cover the sterling silver item or items. Let the water cool, then pour into the sink. Wipe the sterling silver off with a clean, soft cotton cloth.

Also, what is the best way to melt silver? Heat the furnace so it's above the melting point of silver, which is 1763°F or 961.8°C. If you're only melting a small amount of silver, place the silver in the foundry and use a blowtorch to melt it. Once the silver is melted, use tongs to pour it out of the crucible and into a mold.

Keeping this in consideration, what does Borax do to metal?

It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. Borax is also used mixed with water as a flux when soldering jewelry metals such as gold or silver, where it allows the molten solder to wet the metal and flow evenly into the joint.

What does Borax do when melting copper?

The heating action is what triggers the borax to go to work. Once the borax melts, it lowers the melting temperatures of everything in the ore. As all of the minerals melt down, they separate from one another. As the process continues, the borax causes the other minerals to oxidize and breakdown even further.
