Go east they said. it will be fun, they said
picked up about 50 lbs of WW from local garage. sorted them tonight into 3 piles.
1- obviously marked Zn and/or extremely hard
2- marked MC and not so hard
3- soft

are the MC marked weights mixed with Zn? they are relatively similar in weight to lead, just harder.

am going to try casting them separately from the softer weights to see how that goes. anyone wish to give their two cents?
 
if they aren't marked Fe or Zn they are likely lead.

what are you going to be melting it with? try to keep the temps low and you should be fine. if there are some that are suspect use side cutters and that will let you know what's what.
 
If I'm unsure, I throw them in the pot anyway. I use a cheap electric burner from Canadian Tire and even on max heat it wont melt zinc. Any that don't melt float to the top and I scoop them off.
 
I clamp a bar of steel in the vice and tap any suspect weights, listening for that giveaway higher frequency "ting" sound.
Lead goes "thud".
If still not sure, then it gets dropped on the concrete floor for confirmation of sound signature.
'Uncertains' get pinched with the side cutters if they big enough to be worth bothering with.

Lot more "ting's" in a bucket of WW's these days than there used to be.
Serendipity, is the bucket with a high count of dead soft stick-on strips and plenty of those large unpainted old truck weights..

If you can make a significant dint in a WW with side cuttes and it doesn't snap off you have lead. You will not be able to cut zinc with side cutters unless you give a lot of force and like I said it will break or snap off not cut. Lead will dint and cut. Some lead WW are harder then others. More or less antimony
