I've never come across this term*. Of course that doesn't mean that it is incorrect. But I suspect it is not in common use and although I'm guessing, I have a feeling that with the possible exception of one or two Murano glassmakers who might have used this term, it is in fact a description created or misapplied by collectors or dealers after the event, so to speak.
The vase shown on Laura's site is described as having "pasta glass bands". I find that a little surprising, since to most glassmakers, all over the world, these are "trails" or possibly in the US a glassmaker would refer to the one on the rim as a "wrap". I'm certainly not averse to being contradicted on this as I know that Laura has much more expertise in area than I do.
I can see why the figure on Javier's site could be described as "pasta" because it looks as of it could have been assembled from different types of pasta. There is a niggling memory at the back of my mind regarding that type of figure being described as pasta before, but the point I'm getting at is was this the original marketing term or has it become a generic description later?
I wonder if ArtofVenice has an opinion on this and could shed some light on the description and when and where it originated.
*but I will go through all my Italian books tonight and have a look, if I remember!
