Sorry to bump this, but I am really interested in what you think about my "German Uranium sommerso vase"
Am I right that the inner layer is Uranium glass? I guessed so because of the strong green glow in sunlight. Or would a Manganese glow be visible in daylight, too?
And would the thick amber layer explain why the glow isn't visible at the sides of the vase, just at the rim, and why Dirk couldn't see it? (Depending on the design of the rim in his vase).
Anyway, it is an absolutely stunning technique...
Astrid, is this mentioned in the Wiesenthalhütte book?
