David asks: >Why use grain alcohol that has some water in it and would seem to have >some >counterproductive properties Why not use denatured, or does it have water >in it too? Greetings, The "denatured" aspect of alcohol is related to the poisonous additive, which allows it to be sold without the liquor tax. This type of alcohol is, if I rememberr my high school chemistry class, is commonly about 40% water. The grain alcohol sold at the liquor store is 190 proof, which is 95% alcohol. If you try to take it to the purest state of 100%, it will break down into water/alcohol mix of about 95%. Which is enough to make it dry. Anhydrous alcohol is difficult to keep that way, i think it takes a very low temperature. Regards, Ed Foote
