Here is a qustion for soap makers. I am trying to make soap out of 
the waste glycerine. I boiled 2 liters glycerine at 160 degrees F for 
about 15 minutes. Is this enough time to evaporate all the methanol 
out? How do you know when its been evaporated.
I then combined 50 grams of lye/liter of glycerine when both were at 
temps around 100 degrees F and poured into the bottom of a plastic 
jug. Looks like I have round disk of soap. I think I'll try adding 
fragrance to the next batch to see if its workable, just wondering 
about the methanol being gone-which I'm assuming it is. Any comments 
or suggestions? Thanks in advance-PC
