Okay, I get it. I bought a gallon of the stuff myself a few years ago because it was an ingredient in a Liquid Soap I wanted to make. I have not even used up half that bottle yet, but it seems to last forever, so there it sits. Now and then I use it to mix with micas to add to my soap, but unless I make another LS or start making BB products that require it, I doubt I'll ever run out of glycerine.
