Mr. 45nut, Sir:
I was reading the thread ( a "sticky") concerning the removal of zinc with sulfur in the lead, and lead alloys section of your cast boolits site.
In reading about some of the more dramatic reactions witnessed by some of your site members, I recalled from my adolescence the fact that sulfur and zinc , when intimately mixed together make an effective, if somewhat dirty , model rocket propellant.
I thought you might want to be aware of this ( you probably should verify this, as it was a long time ago... ) and probably make your membership aware of this as well.
At the concentrations of zinc generally experienced in lead melts, there is probably little or no danger . But if someone were to try to "clean" some granulated zinc with a substantial amount of sulfur , I would not be surprised if the bottom of a cast iron pot melted out from the reaction.
Again, I'm not trying to cause a panic, I just felt that I had some specialized knowledge ; if it turns out that I'm wrong , please accept my apologies in advance.
( love your site, by the way; - will get around to joining one of these days )
regards,
From a innocent bystander ;-)
