Question regarding black light and cut glass
« on: October 16, 2011, 01:09:20 pm »
Hi everyone!  I've been collecting cut glass for a while now and have recently come across different articles about using a black light to help date it.  Was curious about any opinion of those in this forum since there are some conflicting views online.  Some feel that it is inaccurate because some of the newer czech pieces will still fluoresce.  Would really appreciate any comments. 

On a side note, my husband & I were at an auction this week and he bought me a binder full of "Antique & Collector's Reproduction News" for a quarter.  I couldn't believe that no one bid on them!

Thanks!

I've never heard of that. Have you tried putting the question into a search engine?

You DO use a black light to determine if an item is true Vaseline glass (glass made with uranium glows!!!)

Also newer and older materials react differently.

Maybe this article will help!

Thanks KC.  I had also read that article as well as others that refer to vaseline glass due to the uranium content.  I wasn't sure if the yellow hue given off from depression glass and older cut glass was also due to uranium or something else.  I have tested some items that I have been able to date such as a Heisey Prince of Wales Plumes Punchbowl and it did fluoresce yellow.  I also tested some newer items and they did not.  I am a believer, just didn't know if there might be something else to consider.  As always, thanks for your help!
