Opalescent certainly seems to have had a long life span.......... Salviati and his Venetian revival etc. appear around the 1860's, and as an type of art glass it was still being made as far as I know in the 1960's, but.............. would the earlier stuff have had the gold inclusions etc., and do we think this piece has sufficient of the Venetian style about it? To me this looks too chunky when compared with late C19 period pieces.
Do we know the extent of wear on this one?
