Yesterday i was melting stuff in an iron "crucible" for no specific reason. Today I was surprised to have found several different types of crystals growing on top of some silver metal I had left in the crucible the day before. What I'm wondering now is what exactly can this possibly be? In order to get an idea of what it could be I will list everything that has been melted/burned in it:
Copper Powder
Bismuth
Silver
Magnesium
Borax
When I most recently melted stuff in it with a propane torch, the crucible became a glowing hot orange color. Any ideas of what these might be? Also I'm new to this forum and I hope I am actually asking this in the right place, I don't know where to get help for this kind of thing.
