I did a Google on glycerol alone and found this on WIKIPedia among the uses of glycerol. It's quite interesting. There is an abundance of raw glycerol. Now that I look back on what I did, I'm quite certain I now have propylene glycol with C and Metol base. The viscosity is very much lower than that of the glycerol I started with, and I added no thinners of any kind.

I was wrong when I said I could get gycerol at any drugstore. The local Rite Aid drug store didn't have any and the clerks didn't even know it existed. Their pharmacy may have it but is closed on Sundays. If your local store has Leader brand, there's a good chance they will have the glycerol. I'd have to go more than 50 miles to try walmart, etc.
