Hi all -
We have acquired several buckets full of old Linotype metal - it's a mix of lead, tin and antimony (and maybe some other trace stuff).
There's also a bit of dross and miscellaneous floor sweepings mixed in.
We want to melt it down, clean it up and cast into small ingots for future use for making stuff - fishing sinkers, toy soldiers, ammunition, whatever.
We tried melting some down and got a surface film of gunk - not sure what it is, but there should be a way to recombine the oxides and clean up the melt a bit, then discard the real garbage.
What should we use for flux to clean this up? Ammonium chloride? Borax? Something else?
Thanks in advance
Carla
I called my stockbroker yesterday and asked him, "What are you buying?" His answer: "Canned goods and ammunition."
