Ed,
Your piece is lovely and it icontains zanfirico. I hope you don't think I'm hijacking your thread if I correct some errors in Dean's post. Because Dean owns a store selling Murano, people might tend to accept his judgment, thus spreading some misinformation.
Dean: Your definition of Zanfirico is spot on, and that's the technique in the original vase. However, the definition doesn't apply to either of the examples in your photograph. Your definition of zanfirico states, "A sheaf of rods of different colours is prepared..." White isn't a sheaf of different colours, and a single flattened rod isn't either. The red sections in your photograph are filigrana.
It's also true that latticino, although now commonly applied to white lattice work filigrana in the US and, to a lesser extent, in the UK, isn't a Murano term. Here's Edward Schmid in "Advanced Glassworking Techniques" (a book I highly recommend, especially for how zanfirico is made):
"'Latticino' from the Italian latte=milk. 'A style of cane using only white glass color, often twisted creating a lattice effect,' or so we thought. It's a fiction! [emphasis in original] For a long time Americans referred to all cane worked pieces incorrectly as 'lattticino.' Filigrana is really what we're talking about. "
My concern isn't that you use the term latticino for the white sections in the piece in your photograph, it's that you misidentify the other examples of canes in both pieces. The original piece clearly contains zanfirico.
Ed, sorry again. Portland and Seattle are great sources of Murano, btw. I live near Vancouver, BC and try to get down there regularly.
