Well, finally got the propane and tried out the fire brick foundry I built. Did it work? Yes, melted the rest of the Aluminum I had. It also collapsed! The back was first, it both fell off and shattered as the foundry was in operation. The rest fell apart after it cooled down. Now, those bricks are rated at 2,000 F and the mortar at 2,500 so I’m assuming that the heat was way above that.

So, enter Foundry 2.5

It uses the original foundry whose bottom was melted the very first time I ever tried this, and the bricks from 2.0 as the cover as well as the base. Will fire it up for the first time in about an hour and see if I can finally do a copper melt.
