Glass Chatroom Board

@oklahomasong_Gail Wow, that was lightning-speed fast! Thank you SO much, you have no idea how long I've spent trying to find anything even remotely resembling these (I requested several glass-candlesticks books via my local public library system but have not received them yet...sometimes it takes awhile for interlibrary loan).

So... do they glow under blacklight because there is some uranium content, or is there something else in the glass that is producing the effect? I don't want to call them "uranium glass" in my Etsy listing if that's not what causes it.
