Those chems. do sound bit flammable, though with proper precuations, they're certaninly not dangerous, unless, as Donald menitoned, you were working under the old-fashined gaslight, in which case I wouldn't want to be anywhere near them.

Does anyone have a copy of the article that they could link me to, as I have no way of getting a copy of the magazine?
