I'm trying to find the right type of high temperature resistant ceramic, clay, plaster, or what have you. I have found a huge market in my area, and a lack of metal smiths, so I'm looking at attempting to create my own bullion of various materials. I have access to a professional forge, and will use that until I find another option. I'm in the research stage right now, and I would say that I'm near a point where I will start my testing with cheap materials, but I'm trying to figure out what material to use for a crucible, and with some metals needing very high temperatures, I would need a very heat resistant material. If anyone has any suggestions, Id appreciate it. After hours of searching for heat resistant materials, I keep going in circles, finding things such as High Temperature Furnace Cements, to Fire Clay which seems to just be a wide range of heat resistant clays, and I can't decide which would be best.

Should testing be successful, I would be looking to buy materials, and possibly with bitcoins.

I once saw someone melt aluminum in an old coffee cup. He had unwound the high resistance element from an electric stove then re-wrapped it around the cup. When he ran a current through it it got red hot and melted the scraps he placed inside.
I don't know if it could handle metals with a higher melt point though.
