There is some confusion about the term, but I call the thin veil of tiny bubbbles sfumato. VAMSA might be a possibility?

Shannon, sfumato by definition is the shading of one color to another with no distinct line between them.

I know that's the definition given in some of the Pina books, but I've seen it used often to describe the smokey veil of bubbles found in some VAMSA pieces. So it appears there's some discrepancy.

Of course I'm talking about the term as it applies to glass, not painting.

I did a lot more reading on sfumato. Sfumato means smoky. In glass and painting it is a technique where sharp boundaries are softened by blending or overlaying with something. That something can probably be bubbles, gold, or smoky glass. I am going to have to broaden my idea of what sfumato is. I had always wondered at why the Barbini smoky ducks were called sfumato. I figured they were, but I couldn't fit the design into my narrow definition.

This is nice to figure out. I had been reluctant to use the word because there was so much confusion with it. I guess there wasn't really confusion, only not recognizing all the ways a sfumato effect could be attained.

A plea for help! Sorry to be dense, but I can't see how this ashtray would be called sfumato. I thought the shading from one colour or shade to another was created by the addition or use of particles of a certain type of glass. I'm not sure I see how this would be achieved by bubbles, where it would pulegoso or bollicine. I can see the big bubbles in the ashtray, but am I failing to see smaller ones? I've also been looking through my bookmarks for a site that has an ashtray like this from Czechoslovakia, but I haven't found it---yet.  Anita and Shannon, do you see the other pieces from this person being Murano, particularly the piece with the stretched bubbles?

I don't see the sfumato in this ashtray either, David. I'm afraid the thread turned into a discussion about what sfumato is -- mea culpa -- and got away from the original ashtray. To my eyes the haziness of the glass looks like light opalescence, but I'm not sure what I am seeing in the photos.

Anita: Thanks for the clarification. I haven't found the link I'm looking for, but I did come across picture of an ashtray that explains why I hesitate to call the piece originally shown in the thread automatically Murano, even generic.

I think what appears to be light opalescence as actually a thin veil of super tiny bubbles. I've seen this type of ashtray before, and also the matching lighter, and I do believe they are Murano. There are a couple of similar ones at the Svazzo site listed under Barbini. I do also think the opalescent one with stretched bubbles is Murano.

Sfumato is a confusing term when applied to glass! What many people call sfumato, I would call polveri. But I've seen the term sfumato used over and over to describe this particular bubble effect, which is completely different from polveri.
