    Flowers of sulfur started getting hard to find back in the early '70s, when I was still experimenting with "applied chemistry." So did saltpeter.

    You can buy food grade saltpeter on the 'net now. They limit you to like 1lb a month or so so "applied chemistry" may not be all that useful.
    I imagine that the same places sell sulfur as well but have not looked as of yet.

    I was just wondering the same thing, "Where do you get sulpher?"

    Then somebody suggested a garden shop, and I remembered my gardening buddy using sulpher for the garden.
    Gonna ask him.

    I can get it here at the drug store, right next to the saltpeter. It's sold in 1# white plastic jars. Couple of bucks.

    Isn't powder to keep snakes away made of sulphur?

    I've gotten rid of all the zinc and steel wheel weights (some local tire shops recycle them and I get their stick-ons). If I had some I could reverse engineer a batch in straght wheel weights and see if the zinc I got out was the same as what I put in. I'm probly not the only one to think this.

    I live in an area that has lots of vineyards. Sulfur is delivered to the vineyard by dump truck and dumped beside the road by the ton.

    I think that it would be a "last resort" option. Its easier to keep zinc out than to get it out.

    See that thread in the cast boolits section about 50/50 lead/zinc boolits. Sounds like arsenic may help the zinc blend in?

    At the risk of looking stupid, aren't matches and as someone else said road flares made mostly from sulpher? What keeps these big lumps of sulpher from accidentally igniting into a big fireball? I understand flash points and these temps may be well under what it would take to make sulpher ignite but what if you accidently stir the pot with a spoon that had some wax flux left on it or something?

    I believe that matches and road flares have an oxygen providing compound as one of their ingredients. You would be amazed how quickly a huge number of materials would combust when mixed with a good provider of oxygen.

    Well I've got a bunch of contaminated stuff to try this on. Shore is pretty all gold and blue...

    The colors don't necessarily indicate contaminated alloy. See: http://castboolits.gunloads.com/showthread.php?t=63550 . If it looks like lumpy gray/silver oatmeal that doesn't want to dissolve back in at the lower end of casting temperature, you might have a problem. If it dissolves back in, it might have been your antimony & tin.

    I may have a couple of zinc weights in about 100 pounds of wtts. How much zinc is the SWAN SONG for a batch of wtts???

    Blue and gold colors are not signs of zinc contamination.

    Test pour your alloy, and if it pours well, all is OK. Good luck.

    Do some test pours and see how the bullets come out. If it pours fine, then no problem. It's results we're after, and if you get good results, you're OK as-is! Good luck.

    Zinc contamination

    I had a batch of molten lead, wheel wts only, and as it was close to final skimming and casting into my pigs, it turn very dark, black and powdery, the more I skimmed it the worse it got. Is that a result of Zinc contamination ? Thanks.

    Sounds like waaay too hot. When overheated, ww alloy will form a dross that turns dark and powdery. Reduce the heat a bit-- more heat is not always better. Good luck.
