Unusual Glass Jar
Under the average lighting in a room, this glass jar looks like just a little decorative or minimal use item. However, it’s identifying characteristic is that it glows a yellow-green under UV light. They also noted that the jar had the numbers 1660 and 192 etched on the bottom.
There was a bit of an argument about the glass’s UV tone, some arguing its uranium and others saying manganese. Manganese is used as a clarifying agent in glass and this probably once held a type of cream or petroleum jelly.
