well, shouldn't I look before leaping.......... corroso it does appear to be, and I should also read peoples initial posts a little more carefully, especially where they give their reasons for a suggested attribution.

John undoubtedly knows more about this type of glass than I ever will. My apologies for misleading you.
Sorry to be a disappointment though re your request for value - regret to say that we don't discuss values here - mostly for the simple reason that different people have different ideas as to what is appealing, which means we would all tend to put a different value on the same item.
It also avoids assumptions that selling something will necessarily generate the same value that might have been suggested here.
However, you may get a reasonable guide as to the value of your piece, from other internet examples which will almost certainly beaccompanied by a value/price, and now that I've looked, there are many examples of corroso glass on the screen - if you use Murano and Corroso you should get plenty of examples to see. Previous auction sales are also a good source of indications of monetary value.
Wish you the best of luck.
