Not being an expert, I would defer to Dick and Larry since their opinions are the same as what I have heard from other folks. Contamination due to impurities is the problem and not pure zamac itself. Now comes the tough question: How can a person without a research laboratory at his disposal determine if a product is made with pure zamac or contaminated zamac? Any thoughts?
