Today I tried melting brass for the first time. I had some nice heavy brass padlocks around and so I dumped them into my 4" pipe crucible. After2 hours and several pounds of charcoal the padlocks were orange but simply the brass did not flow. I did not took the steel pieces apart since I'm lazy and I expected to fish them out when the brass melted. Is padlock brass the yellow brass novices are cautioned against? If so, what would be a common scrap source for silicon bronze? Taps, hinges, fittings, something?
