Casting Epic Fail! + 3500 °c in home made forge!!! here is my casting fail! i was going to cast some aluminium using lost foam casting like I have done many times before but i didnt realise that i was using steel to melt in the crucible in place of aluminium i melted most of the steel and was about to pour the metal but then my camera ran out of battery so i had to go and get the spare. when i got back the forge was going crazy hot and the crucible (made of graphite that melts at 3500 C) had a hole melted in the bottom! that is crazy hot!!!!! i will give this another go once my new crucible arives!
