I get free ww's from my local shops, and the mix always has tape weights and some steel clip-ons as well as about 80% are lead clip-ons.
What do the zinc ones look like?:???: Do they melt just like lead at the same temp?
and will they screw up my hardness if included?

They float to the top, just take them out.

The oatmeal looking stuff, flux back into the mix, that's the beautiful antimony.

By all means, isolate the zinc.
It makes great sling shot balls.

What do the zinc ones look like?:???: Do they melt just like lead at the same temp? and will they screw up my hardness if included?They can look just like the other weights, "some" have Zn on them but if painted you can't tell by looking. I snip all weights with wire cutters and if it feels any harder than it should it gets tossed. They also melt at a higher temp than lead so will float to the top and should be removed. Zinc in your alloy can make for very very frustrating casting cause you can't get good mold fillout.

They are of no use to boolit casters. Jig and fishing sinkers may be a use for them.

If you are tossing them out, toss them my way.

Get one of the flat rate boxes and line it with plywood. Fill the box with those throw aways. When the box gets full or 50 lbs mail it to me and I'll send you your postage back.

I tried that and got blisters after a while. Now I melt as low temp as possible, and all non-lead including zinc floats to the top where it's promptly removed.

Shoot, I have been throwing my Zn and Steel WW in the recycling... .95/#, I am missing out.

I should save them I suppose since I make fishing sinkers and lures. The lures require soft lead and a bit of tin for maximum fill out, but zinc should work fine for the sinkers.

If it's like they do business on everything else, the recyclers around here would probably charge you $1/pound if you wanted some zinc but pay you $.10/lb if you had some to sell.
