so, because i recently acquired a large pot to smelt with, for the first time, i actually sorted through every single wheel weight in the bucket prior to smelting. i only found 1 zinc weight (and 3 stick ons) that were not lead alloy. is this normal? i used a SMALL pair of spring loaded (so they automaticly open) electronic diagonal uutter to check the weights. i went to the edge (where the weight was thin) of each weight, and tried cutting into it. the one zinc weight i did find, was quite hard, and with the pressure i was exerting, wouldn't even hardly scratch anything but the paint. while everything else either dented quite easily or actually cut through. i did not put a lot of effort into cutting any of them, as i knew i had a LOT of weights to check. is this as good of a test as most others? i also looked for "zn" on any of the weights but even the one i did find did not have that on it. i also did not find any "floating" in the slush of ww's when smelting, so i dont think (unless the melted at the bottom of the pot) there were any. i just hate second guessing myself, it just seems strange that there were so few. i wish there was a good easy 100% positive way of checking. it was interesting noting the difference of hardness in different brands of wheel weights. you can definitly feel the difference between some of them.
