Stu it would surprise me if they were uranium, though. Earlier production (pre-war) from these factories in green maybe. What you are almost certainly seeing is a dull green glow best seen in the dark. That is caused by manganese, which was used as a decolorising agent until it became too expensive, yes even in coloured glass.

Uranium gives a knock your socks off bright green in daylight, although it's sometimes hard to see in bright sunlight. Your Bagley Wheatsheaf might have been a better bet. Although all green Bagley does not contain uranium, only older stuff and some ranges are found in both.

Great information Christine, as ever.  :thup:  Thanks for that.

The manganese sounds spot-on, as they don't glow as I imagined uranium would (have still to actually see this ::) :))

Oh well, I will keep on searching.

You'll know when you find it. Took Michelle a while to see the light (the right one)  :24: :24: Just keep waving your torch at green and yellow/green glass
