Jadite

I found this piece of glass at the beach below Deception Pass.

Jadite is a type of glass that comes in a variety of pale milky green colors, resembling the color of the jade jem.  Jadite is a trademarked name that was originally given to a specific color of uranium glass.  You may recognize this color because it has become very popular and there are many reproductions.  Jadite was made popular in the 1920's and 30's, by the Jeanette Glass Company.  It was an inexpensive Depression Era glassware.  After doing some research, I found out that uranium glass has been made since the 1830's, with the Jadite version arriving in the early 1900's.  Uranium glass glows under a blacklight and also registers a slight radioactivity when tested with a Geiger Counter.  Not all Jadite was made with uranium glass, but I just might have to check out if this piece was.  Anyone got a blacklight?
