A technique invented by Carlo Scarpa for Venini & C in the late 30s.It is based on the traditional 'Filigrana' technique. Thin glass rods of different colours are joined together into thicker rods. Then they are cut into pieces, butt-jointed on a metal plate, melted and then shaped.
In the 50s, Paolo Venini invented a variation of this technique. He cut the rods into smaller pieces and put them together into mosaics. Glass windows were made alike. The architect Gio Ponti published them in the journal Domus. Paolo Venini exhibited the 'pezzati' technique with orthogonal arranged elements, in 1954 at the Triennale di Murano.
