Well, safety gear, don't have any other than my black smiting apron.
I made me a small flask and I am using fine beach sand and oil I mix. The object I am making is very small about 2" long and a inch
wide. I been watching 100 or more youtube videos for over a year now. The heat( this so nice to be able to talk to some one)
10% over the melting point or more? I have the temp of 1983 deg. for copper. 10% will be 2176, would that be good or make it even outer?
