thanks for changing the title....i would not have looked otherwise. I don't know who made it, but have come across other things that were blue/turquois/teal in color that were uranium reactive. Sorry I can't be of more help. I am color blind and for the most part, only see yellow-green uranium. I don't see greeeeeeen depression, or teal, or burmese, or custard, or any of those other UV reactive glass. my eyes just sorta glaze over them. When it is yellow-green, though, my eyes get really serious!
