hello i was just wondering why there isn't much about copper on here also i was wondering about a project i'm about to start i'm making my charcoal furnace right now one question i had is can you use straigt coal to melt al and copper? i have used it to melt al in a dug out hole in the ground with air from my compresser and it did fine QUESTION NUMBER 2 i'm wanting to copy some arrowheads i was left by a family member and maybe sell them as neclaces or orinaments for your rear veiw mirror would copper or al be better and what would be the best way to mold them any help would be great


thanks from wv

welcome to the forum firstly copper melting is just under cast iron....to melt copper you will need a oil fired furnace you will need graphite crucibles...so unless you are willing to invest big dollars??????most settle for aluminium and brass.which is very much cheaper as a hobby......arrow heads!!!!! we see heaps of them here in australia... we see them in pewter ...brass....aluminium....copper (but these could be brass copper plated!)
