is their a quick, effective, and cheap way to recover tin from soup cans?
I am thinking something along the lines of either submerge them in molten tin for a few minutes, or try to reverse electroplate the tin off. I am not too worried about how pure it is because I want to try and make a deformable hammer out of tin because it is less toxic than lead, but about as malleable.

Thank you!

Tin has a VERY low melting point so a large crucible a good supply of gas is your easiest choice (gas like propane or OBP etc).

It melts below 450. So if you don’t care about costs you could even use an electric heat gun. In theory.

Here’s the catch

Food cans aren’t tin. They’re tin plated steel, yes, but there’s a long-chain polymer plastic coating over the tin. Not good to breath. So use a mask or respirator and do this outside.

Thank you!

I am aware that the cans are very thinly tin plated steel. Which is why I was wondering what the best way to remove it was.

Oh, you miss the point of concern: the plastic coating.

Again. Use protection and do this outside safely.

Ps: a heat gun does actually work. Just not quickly.

You would be better off going to the local flea market or a couple of yard sales and picking up some lead free solder. Most newer solder is 95% tin. Much cheaper than what it will cost to recover the tin from cans and a lot safer. I have seen a lot of rolls at flea markets and usually only a few bucks each.
Just my thoughts
