Vaseline glass has been used for over 100 years to make kitchen ware, home decor objects and
jewelry. What makes vaseline glass unique is the fact that it will glow a bright neon green color when it is exposed to a ultraviolet or black light. This glowing effect happens because DEPLETED uranium dioxide is an ingredient in the manufacturing of the glass. If you aren't familiar with this type of glass do an internet search for "vaseline glass" and you will see all types.
