This is just a VERY basic rudimentary first cast. I couldn't get it hot enough to do aluminum but I had a ton of lead items in the metal bin. Will make a few changes to try and insulate it a bit better. Hopefully that will get the heat up.
For those interested it is a Ceramic Jar with a stove heating element wrapped around it, insulated with fiberglass and sitting in an old pot. The pot handle definitely came in handy :p
