How to melt down copper coins?

Copper has a relatively low melting point, around 1075 degrees C. You can melt small amounts with a blowtorch. To melt enough for casting you’ll need a furnace of some kind. This need be little more than a couple of tin cans and some perlite insulation material.

How to connect copper to galvanized plumbing?
