Both uranium and selenium in a weird glass basket? Czech?

<< < (4/4)

Adam:
Both manganese and selenium, the latter usually with cobalt, can be used as decolourisers depending on melting conditions.  I can't imagine uranium being any use for this although, as I keep saying, I am hardly up to date!

I would not be that surprised to find strange combinations in any country's glass.  Historically, at least here in the states, if a batch of glass was a little short, factory workers have been known to throw in a batch of cullet to bring the measurement up to specs.  Since they were not so careful about colors, all sorts of strange combinations show up.   End users apparently did not particularly care if a canning jar came out citron or apple green instead of the "true Ball Blue" or if a whiskey bottle was lemon yellow as opposed to the more normal honey amber.  If the product served it's intended purpose, both buyers and sellers were happy.   

My guess is the thinking would be glass is glass.  If it looks OK under normal light on a store shelf, that is all that counts.
