Thanks David.

The Wolf Trapdoor book has a little section on testing for hardness and lists pure lead as hardness of five, but he also lists plumbers lead separately. The indention for the plumbers lead is pretty close to the pure lead in his table.

I guess in this case close is perfect enough right?

I am new to casting and especially mixing the alloys so I just want to be as informed as I can be.

It will be interesting to repeat the hardness test after I mix the tin and compare to his table.

The alloy I need (20:1) should be around 9.5 - 10 BH. I am mixing 1oz 50/50 solder with 16oz of the plumbers lead.
