anyone ever make their own Tins?

Thanks a million

good questions

-seperate? , i guess normally you would not need to, just that if you melt a large batch of it, you are comitted, its no longer lead free and never will be. I am very careful not to ever get the 2 mixed together (to meet Californias strict Prop 65 laws) so I guess thats where that comes from. In other words if I get lead into a large pot of Tin, its now no longer Lead Free Tin, periond. even a bb size is enough to "contaminate" the pot.

-yes Im sure you can buy 6/40 blend of tin lead or whatever Alloy you desire, mixing it is ok too, just make sure you use a good flux to blend it all together nicely. only thing is to make sure you use LEAD, not tire weights which had many tramp(unknown) metals, these can greatly HARDEN the finished product. In fact Antimony will really harden it, so much so that it may become very brittle, whereas tin bends easily

-Copper melts? I dunno, i can look it up i guess.
I think your question is how does it get into an alloy if its melting point is obviously HIGHER than the Tin at 459 F ?
great question, I dont have the answer, same way I cant explain how SALT which melts at about 1400 F gets into salt water. Thats why they say its in Solution, not Melted . And it will just as readily Crystalize right out of solution too, just like Rock Candy, or salt crystals.
