Glycerin itself is a non-toxic liquid usually made of fatty acids that often make their way into our foods as a sweetener or preservative. It’s also a popular moisturizer in soaps. Its high melting point and gel-like consistency upon freezing makes it an ideal alternative to ice in bongs, since it will stay in place and remain frozen for much longer than ice.
