Both uranium and selenium in a weird glass basket? Czech?
David E:
Quite possible to have both elements included - perhaps a technologist can back me up, but both uranium and selenium are used as decolorants, so both together may have proved more effective.
Edit: Anne, I've added 'Czech' to the title so Marcus can identify the post.
Lustrousstone:
I think you mean colorants, not decolorants. Manganese is a decolorant
David E:
Not necessarily. I always thought manganese was the older way to decolor glass, but selenium was used later. Found on Great Glass

Probably not copyright that so-called "author", despite what it says on the web page!
I think the same applies to uranium, particularly when used with other elements, although the side effect is the glowing, of course. Edit: In this case, it is used as a colorant, of course! 8)

Might be, but is it never says who the author is when he sells their work.
p.s. Not on Great Glass...
glasswizard:
Anne, your piece is lovely and then Andy really grabbed my attention with his.
I have this piece, the color I would describe as either lime or apple green.

Its 15 inches long, 7 1/2 inches wide, and 4 1/4 inches high. Mine has a lable that is black and gold and reads "Coyne's Made in Czechoslovakia" Being a Beranek and Skrdlovice lover, this thread has made me wonder about what exactly I have. Terry
