#4 8KG MegaCast Foundry Clay Graphite Crucibles Black Cup Furnace Torch Melting Casting Refining Gold Silver Copper Brass Aluminum

#4 8KG MegaCast Foundry Clay Graphite Crucibles Black Cup Furnace Torch Melting Casting Refining Gold Silver Copper Brass Aluminum

Q: Do i preheat it to 400 C or F for an hour?

I have no way to measure the temperature. Just know that I heat it slowly nd it has tolerated the melting of brass well.

Q: Worst case scenario if I tried melting aluminum in a charcoal forge with this product?

I use mine in a pellet burning furnace

Q: Instructions say to cure crucible in oven with borax. But borax melts at 1,369*F. Does it mean foundry instead of oven?

I just put mine in the house oven and set it for max temp. I set the oven to "self clean" which heats and holds higher temp. seems to have worked fine.
