Looking over one of my posts, I see that I've quoted someone as saying Martinuzzi's pulegosa was "more coposteriorly bubbled." I'm not sure what coposteriorly means of where the heck the word came from, but it should have read "more coarsely bubbled."
I checked another couple of sources. The Deboni Venini book adds a little to what we've been saying. Pulegosa "consists of a spongy pasta vitrea
full of irregular bubbles of air, created by pouring a substance which provokes this reaction into the molten paste." So the texture comes not just from the bubbles but from the glass itself. Deboni doesn't define bollicine at at all, although he defines Scarpa's sommerso glass as usually containing a layer of bullicante
glass. I find that quite confusing as I've always though that bullicante glass was created by spike moulds or a mat of spikes on the marver.
Finally, I went to the Barovier and Toso website (http://www.barovier.com/s_community/voc_detail.asp?id=147
), which I should have visited first. It simply says that a bolle and bulicante are the same (spike created bubbles) and pulegosa = bollicine. That makes the most sense to me. I'm joining Anita in ignoring bollicine from now on.
BTW, the third piece in my pic was Scandinavian, Randsfjordglass by T. Torgersen. I think the bubbles were created by the picking up a powder from the marver and then dipping the piece back in the pot.
Just to keep the conversation going, though.... Anita uses bolle to describes big bubbles, but I think bolle is when a spike mould is used. There was thread recently where someone described how Erickson glass made large bubbles by incorporating glass peas in the gather. They melted leaving a bubble. I think that's how the larger bubbles in Murano were created. I was also looking at all my bubbled pieces and some that I thought were puelgosa because the bubbles seemed random, were, in fact, bolle/bullicante, as several layers of glass had been consecutively rolled on spikes, so the bubbles were at different depths in the glass and looked random. I think Seguso did this.
I promise to stop now. Hope this hasn't too pedantic, but it helps me figure out what glass is all about.
