I thought about the 50-50 mixture because that way would be a little denser than lead,but harder than pure lead..
DENSITY MELTING POINT MOHS HARDNESS
COPPER 8.94g\cm3 1084 C 3.0
LEAD 11.34g\cm3 327 C 1.5
So the 50:50 alloy would be about 10g\cm3 it would melt at 1084+327\2=705(???)C and would probably have the hardness of 2.25 (?) And about the historical axes and other bronze stuff,i knew that tin,arsene was used most often,with 1-2% lead added to sword bronze for easier hammering,sharpening.The casting will be surely captured;the bellows are in a phase that one bellow is a sheep skin without fur and the other one still has fur
Made 2 ~250ml crucibles and a small ~50ml one,from clay with 1\3-1\4 sand in it,still have to be fired,on the left there's the blowing nozzle of the bellows system already fired and a lost wax small scythian style axe mould with 75% or more sand so it won't crack at shrinking on the wax positive inside it,and a dagger mould which might not survive as it's pure clay and thick...The bellows and wood pipes are the next thing to make.The progress is slow,but it's progressing a bit weekly.
