I shall take back my apology for sending the K chlorate (not perchlorate) as someone called it, because I did that reaction so many times I almost-- but did not-- tire of it! I was readying for a cruise through the Panama Canal right after the New Year, and just forwarded most items with a quick read only. Cary is absolutely correct suggesting using Na chlorate: it melts more smoothly and at a lower temperature, and I think it is less costly. In fact, there is nothing to prevent you from melting the chlorate with some sugar from a restaurant package gently mixed with it. I never had an accident, no one ever got hurt; and in the old days of "what do you mean by lab safety?" (only safety glasses) I permitted students to determine if they had Na or K chlorate, using a pinch of the chlorate whhich I placed iin the test tube.
Happy New Year.
