A source of pure TIN

[Soundguy]

I mentioned that the foils I had melted into known pewter at around tin liquidus temp. I neglected to add that the melt was a large lot of pewter I had analyzed: no aluminum, just tin, a little copper and antimony and a touch of lead that I believe came from an old, non food service pewter item. I’m comfortable saying the foils were mostly if not completely made of tin.

Antimony is as or more toxic than arsenic.. hope there wasn't antimony in it...

Confused? Most of the lead we use as reloaders has antimony in it, It is not toxic in it's alloyed form.

My point was that finding it in a bottle top foil was surprising... Definitely not cali compliant.

I just bought a book, you know, made out of paper with printing on it? And it was listed under Cali. Prop 65!!!!
ANYTHING is unhealthy for you in California.

Probably the ink..

I wasn’t very clear in my statement.

I melted the foils into a pot of pewter. The fact that the foils melted around tin liquidus temp suggested a high tin alloy, not lead or aluminum. The fact that, on XRF analysis, the whole pot, including the melted in foils only contained metals that I expected in various types of pewter (tin, of course, several percent antimony, a smaller percentage of copper, a very low percentage of lead, and no aluminum at all) made me comfortable saying that the foils were tin, not aluminum.

Another source of pure tin was ointment tubes .........I think even toothpaste was in tin tubes ,but not so sure of that.

Man! That is going back a few years!! I remember them in the trash burning piles, they would swell up and pop. I never remember them melting though and I think if they were tin my dad would have held them aside for that reason.

Long ago and far away...

As mentioned earlier, one can also find tin foil on some wines; typically the spendier ones.

See pic: Tin left and aluminum right. Beyond visual differences, tin will have more heft.

I wish my wine bottles were sealed with pewter, if so I would never be in need of any. Unfortunately, they are only aluminum.
