Ahh, ok, thanks for the refresher course!

Yeah, I'm not too sure about this Sorbitol either but I'm using it for my screen plate as per PE's suggestion. It's supposed to make my gelatin more easily soluble, but isn't gooey like glycerin. It's a humectant and has a high refractive index.

I'm picking some up tomorrow from Walgreen's, and of course the pharmacist thinks it's because I'm constipated....
