Anyone know if this is pure tin. Seller told me that it is tin. Anyway to test this. Just wanted to know the contains before I mix them.

Is that solid or hollow, and what is the diameter?
Hollow, diameter is approximately~ od 0.95 id0.71. Thanks
Pure Sn crackles when you bent it. Not sure if over 95% pure Sn also do same thing..
Pewter which is probably around 95% tin certainly crackles.Originally Posted by Teemu
92% to 95% & pure tin will dissolve in muriatic 32% acid. Clip off a small bit . A gram & dissolve in the acid. You will be making Stannous Chloride, a Gold testing solution. unclemikeinct
That looks like the old tin tubing used in pop machines.

From my limited testing, putting a high tin alloy like pewter into a bath of pool acid steadily produces fine bubbles as it dissolves. There is no vigorous "boiling" as there is with zinc. A fine black residue is left after the solid is gone, which I guess is made up of compounds of the other metals in the pewter.
Will the muriatic acid gallon jug from hardware store works?
The crinkling sound is pretty cool. I have never heard it with lead free solder though.
Here few more pictures, it's very soft easy to bend and does make a crinkling nose. Safe to say it's tin?
One more
Tin melts at 450 degrees F so you can melt it by itself in your pot and check the temp just as it melts.
Great advice. I will melt it into ingot and check the temperature when it starting to melt to make sure they are tin. Thank you everyone
It's what I use.
Be advised: this stuff is great at eating holes in your clothes. It also can fume a bit, which is not only bad for your mucous membranes, it will instantly rust steel tools on a pegboard just behind and above your bench top (don't ask...).

Wear good eye protection when handling acids! Also stay upwind of the fumes. Little invisible drops will ruin your clothes, your shoes, anything it touches. I used to use a lot of it in the lab.
Tin tubing was used for running beverages through to cool them. Beer was cooled by running through tubes that wrapped around a tub with a block of ice and water to cool it. "Ice Cold Beer on tap" was at one point how it was cooled. Organs can also have tin tubes.
Tin will melt so easily compared to zinc you won't mistake the one for the other. If you have some known tin such as pewter that you can melt and hold at close to tin melt temperature then stir with the unknown suspected tin it will melt or won't if it does melt then it is more tin. If it won't melt at the same temp then it may have some lead in it if it melts pretty easily when hit with a propane torch which would be a higher temperature.
If you have some lead free solder a piece next to the unknown then hit both with a propane torch. If they both melt at the same time bingo they are both tin.
Tin does cry or crackle when bent but hell if I could still hear that I would hear everything the dear wife says the first time and that doesn't happen either.
Scrap.... because all the really pithy and emphatic four letter words were taken and we had to describe this source of casting material somehow so we added an "S" to what non casters and wives call what we collect.
Kind of hard to claim to love America while one is hating half the Americans that disagree with you. One nation indivisible requires work.

Yep, that's pure Tin. AKA:beer cooler line. AKA: Block Tin.
I can't remember why the Professional Scrap guys call it Block Tin? But that is what they call it.

Thank you for identifying it. I got 40lb linotype pigs that needed tin to mix in.
Have never seen 40 pound linotype pigs. Usually they are 22-25 pounds. Photos??
Maybe you are talking about having cast lino scrap into large ingots. I would think there is a difference in terms.
