Today I'm building a better foundry. I use insulating fire bricks, some paper, a simple saw and a block of wood to shape it all. Next time I'll build an enclosure (as opposed to shelling out lots of money for a keg. I'm not made of money) out of sheet steel and apply mortar and a coating, made from satanite. Then it's time to start melting metal! This is intended for use with a burner, such as propane or oil. This will NOT work well with charcoal.

This foundry furnace will be used for casting aluminum, brass, bronze, copper and other alloys. Probably not cast iron, though.

I got the bricks here: https://www.armilcfs.com. They have kaowool too and some other stuff.

This replaces my old furnace which I build in the video "how to build a better mini metal foundry", published months ago. That furnace, based on grant Thomson's mini metal foundry, used castable refractory cement instead of plaster and sand. It is still holding up, but insulating fire brick insulates better. The old furnace build is here (don't watch it, this new one is better) youtu.be/VSsPHwWB_pI
