There is precious little information available about the Cristallo Venezia CCC glassworks. There are just a handful of labelled examples that can be found online. The gold and silver foil label reads "Cristallo Venezia", with a rectangular banner across the bottom that reads "C C C". An identical label has also been found that reads "Artistica Murano, C C C", indicating a factory name change to or from Artistica Murano CCC at some point. Of the few online labelled examples, production seems to be mainly sculptural bowls made in the sommerso technique. Common characteristics include a distinctive star shaped base, hot worked curled and cut out "maple leaf" shaped rim, and colours that fade from dark to pale or clear.
Please note: As mentioned, there are very few labelled examples to be found, and much of the information included here is speculative. I have tried to group together similar examples, but it is quite possible that other factories produced similar work, and therefore not all the pieces shown may be by the same factory. In fact, very similar designs are now known to have been made by Formia [see here], and Ferro & Lazzarini. I will add new information as it is uncovered. All the glass shown here was bought in the UK, unless contributed by others.
