The only wood fuel that will get hot enough is hardwood charcoal - not briquetts. And you'll still need to force alot of air into it. Sounds like you've got alot of scrap which could be anything including Aamco 18, babbit, silicon bronze, manganese bronze, aluminum bronze, etc. I wouldn't try melting it unless I knew exactly what it is because much of it would be incompatable with each other. You'll have to do the silver nitrate test, the nitric acid test, and others to determine what it is. Some copper alloys melt at a higher temps than some cast irons so I wouldn't try to do it in a frying pan either. The handle is sure to droop. Make yourself a crucible furnace amd do your melt outdoors especially when you don't know what the alloy is. Some of the vapors can be poisonous. The previous guy was entirely correct when he said pure copper has an affinity for gas porosity.
