Christine, both sizes come with and without uranium. The non-uranium ones are orange/amber
cased with a layer of green - therefor the green look of the bumps on Jeanne´s piece.
The uranium ones are made of an amber glass mixed with uranium. I suspect, WMF
stopped using uranium at a certain point, but continued the design; but that´s just a wild
guess.
There´s still a chance I misinterpret the picture. :kissy:
