Hello!
I'm a modest
glass collector and not a top class specialist but to me both the
red and the green artefacts look immediately
fake.
This white deposit ont he
red is typical of
fakes, as there is no coherence between form, molded decor and marbled
glass, the deposit and the very fresh aspect of the
glass, and the fact that this opaque
red glass is shiny.
The deposit ont he gree looks absolutely not ok, as the transparency, color in transparency and aspect of the
glass.
I'm not even speaking of forms, because even they look like nothing, I'm the first to think sometime we can find special unreferred forms, that was my case, but here out of the form nothing looks ok...
You can maybe ask an advice from Bron Lipkin
http://www.collector-antiquities.com/home.html he will give same advice I think (I would be happy for you to be wrong)
