"using it for ingestion" = "drinking it" You will soon be visited by Jacques Barzun and put to death in a most unpleasant manner. Methanol is wood alcohol. It _is_ drinkable -- but poisonous. Among other things, it causes blindness. I've never tasted denatured alcohol -- a few drops are harmless -- so I don't understand why denatured alcohol is "undrinkable".

Right. Methanol is a very poor denaturant. The idea is to make it undrinkable, not lethal. Someone ralfing their guts out for an hour is cheaper than blindness or death. Now, Sterno...
