Glycerine acts as a binder, blender, stabilizer, and antifreeze when you mix it with glands. Glycerine can also be mixed with urines to add body and to prevent evaporation when exposed to the air and to prevent freezing. We personally like to use Glycerine in our urines for freeze proofing. Shake well after mixing.
Glycerine will not preserve your glands or meat. Add some sodium benzoate to preserve your glands and baits.
