Re: Lead Hardness
lead just right ?
dont ask how to get it just right
there'll be 4000 answers and most very different
pure lead is a bit soft , zinc is safe to use as a hardener 12 parts leads 1 of zinc but you have to get the temp up and that risks lead oxide fumes so only outdoors and with a particulates mask eh
antimony is better but expencive thats what they use in printing plates along with tin
14 lead -20 lead pats per 1 part antimony
tin can be added too but again you'll need to get the temp high
12- 19 parts lead to 1 of tin
your choice on the mixes
mine is 37 parts lead 1 of tin and 2 of antimony
fluxed well and away we go
