Faceted items similar to the ones shown below are most often attributed to Mandruzzato, who have been making this style of glassware for many years. However there have since been several other factories in the Murano region which have made pieces in this style, and as such it is difficult to be certain of the manufacturer without labels or signatures present. Other well known manufacturers that have produced glassware in this faceted style include Campanella, V. Nason, Formia and Oball. The vast majority of these faceted Murano glass items contain two or more suspended coloured layers of glass in a third layer of clear glass, using the very popular sommerso technique.
Important note: As with most sommerso glassware, it is very common to find these wrongly attributed to Flavio Poli, a designer who became famous for his sommerso designs. However, Flavio Poli worked for the Seguso Vetri d'Arte factory, whose designs are very well documented, and there are no records at all of them ever producing these faceted sommerso items.
