Topic: Clear and Opalescent Uranium Vase.

[cagney]

  The reason we call it fiery opalescent over here. The conditions under which you photographed  your glass had a lot to do with the effect I think. So I tried to mimmic your conditions. Although the creamer is not as dense? [for lack of a better term] in opalescence as your vase. Some success achieved and managed to isolate  the most dense area, the pontil, and a nice purple red much desired by amberina collectors appeared. The lacy plate an after thought, but does show the effect in a small way, purely by accident.

[flying free]

Just to add the foot on my vase was made separately and applied to the base of the vase. This would explain why it is a bit misshapen as the feet were often made by lesser skilled workers or apprentices. I've seen it on other pieces but with this one in particular when held up to the light, the opalescence turns to amberina.

It doesn't turn to amberina - it looks amber/red in colour when held to light.  This effect comes from the recipe used in the making of the batch.

I'll try and find a link to the explanation of how Murano girasol glass is made .  edited to add:
