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..
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?

Tin melts at 450 degrees F so you can melt it by itself in your pot and check the temp just as it melts.
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.
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.

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.
