I was sorting out winter WW score yesterday and today. Found few zinc, iron and other surprise weights, so I decided to post some pics. I know some are just ignoring zinc and scoops them out from the top of the alloy; but I can't do that, with my luck I slip too much heat there and they are gone from the top. Besides sorting stick-ons is done with the same effort. This is kind of update to this thread:

I realized that best method to separate zinc weight from lead alloy weight is squeezing it with pliers; depending of the pliers strength it's very easy to cut a mark to normal lead weight, but next to impossible to cut or squeeze a zinc, not to mention iron weight. Difference is very clear. Last year I used knife and pliers are much easier and faster.
In addition to above testing with pliers, it indicated very big differences in hardness between weights. Many old bulky weights are very hard compared to more modern weights. Some clip-on weights seem to be near pure lead, but with minority share. Almost all stick-on weights are very soft, probably near pure lead (that's why I separated them), but there's few very hard ones in them too.
Finished lot here; bucket full of stick-ons and some "environmentals":

Here are some of the suckers:

I've seen many reports of riveted zinc weights, but all riveted what I've seen are iron weights like the ones on the right.
On the top in the middle there's new to me zinc stick-on weights, addition to older threads types.
On the bottom in the middle there's many versions of very common weight type, most of this kind are lead alloy, but quite many are some very hard metal, perhaps zinc and maybe something else, but pliers won't hurt them much even from the edges and corners.
Real zinc suckers on the left; these are all very nasty ones, perfect copies of very common lead alloy weight types and many of them were perfectly just enough dirty to hide themselves very well. All of these were marked Zn, but sorting them is pain and I squeezed hundreds of lead versions to make sure they are good ones.
The broken one below is almost all plastic, very light, but inside there was lead alloy. No need to save these, must broke all of them to be sure because new ones contains some environmental **** I'm sure and so much plastic is pain to burn off. Fortunately there was only few of these plastic ones and alloy loss is minimal:

There was a nice small bonus too:

About one pound pure tin; most were marked Sn, but few on the right were not. Shiny appearance exposed them and squeezing them with pliers right next to my ear confirmed that. Now it would very good idea to advertise qualities of tin weight to whole world, especially for young men driving nice cars and hunting chicks...; Tin weight rules, it makes you feel better, it makes your car faster and improves handling characteristics, with wheels balanced with tin weights you're always on time, you hit the destination earlier and there's no need for that funny guy on TV to pimp your ride. You even g*t l**d easier and it tastes better even if you have to diy for some reason. If that happens be sure to rebalance your wheels with brand new tin weights! Iron makes you feel rusty and zinc weights surely causes anor*asmy and other nasty inabilities... Beware of zinc if you drive :Fire: !
