Thanks David, Yep I see them.... neither are attributed as you say.
So does that mean unattributable ? or just that Philip & Ann don't know. They are immensely knowledgable but nobady can know about all types of glass and Murano has to be one of the hardest.
Ray, I always used to think of Nason when I saw this type of glass with so much adventurine, ....especially when embedded in a dark color, which online seems to be generally attributed to Nason. But recently have noted a number of other makers in my books and online who have used this look...most recently in Pinas Fratelli Toso.
Javier any thoughts ?
