I think glycerine just helps it make the solution abit thicker.which helps it stay on.also helps keep tobacco in case,and stops it going completely dry.like propylene glycolI've used glycerin before, wish I hadn't. I've used it in casings before as well as without. IMO when mixed, I never noticed a difference with or without. Using it pure made a semi-sticky leaf that for me atleast slowed down the burning a lot but just wasn't something I wanted to smoke too much.
