Sue -
Facon de Venise, or more correctly
Façon de Venise, was a very specific term to describe C16 and C17 glass made in the Venetian style, initially by emigré Venetian glassmakers and later by those they trained. Made in several parts of Europe, including England, to satisfy the huge increase in demand for quality glass, the bulk of the production was in the Netherlands. It can be very difficult indeed, sometimes impossible, to distinguish between
Façon de Venise and the contemporary glass made in Venice. From memory (mine has been tidied away somewhere) Mark West has a useful 2-page illustrated introduction to
Façon de Venise in his Miller's Guide
Glass.
Unfortunately the early date requirement has been relaxed, initially by optimistic auctioneers and proprietors of expensive antique shops, and now by eBay sellers, all looking for classy words to describe their wares. So now you can't rely on this sadly abused term meaning little more than old-style Venetian repro. I've even seen it used to describe modern old-style Venetian made on Murano, which is tautologous in the extreme, and makes me laugh (or weep tears of pity)!
So, Sue, if your lovely comport was made on Murano, it cannot be
Façon de Venise, or, at least, not unless you are in the habit of saying Stourbridge glass made in Stourbridge or Whitefriars glass made by Whitefriars.
