Uranium Glass, also known as "Vaseline glass" is colored yellow to yellow-green by uranium content. If you expose the glass to UV light it'll glow. The glass was produced in the 50s before the radioactive properties were fully understood. Get it while it's hot!

Implications - Today, most products that use uranium use it in a depleted state for safety purposes. The featured images show products that were created with natural uranium which causes the alien glowing effect. There are still a few companies that make Vaseline glass such as Boyd Crystal Art Glass, Mosser, Summit Glass and Fenton Glass. The items that they produce are strictly for decoration and not meant to be used as dinnerware.
