You might not have thought of this but if you enjoy higher $$ end corked and sealed-with-foil single malts and whiskeys like I do, that seal, cap, and neck band are pure Sn! Not aluminum or lead foils.......but Sn. Cheap bottles use Al foil and/or Al screw caps with plastic film seals. You can tell just by the weight and feel!
I just got done re-melting and fluxing about 2 years' worth from me and several friends that donate them to me, and I ended up with a little over 4.5 oz of PURE TIN. Not bad for something most people just throw away.
I really do not need it, as I have currently over 200# of pure I use for casting.
But everybody out there seems to be in a desperate panic/search for Sn, so there is a source for a little. Will sweeten several boolits!
Talk to your friends and relatives that enjoy a really good quality "wee dram" now & then! And have them start saving the bottle foils for you.
