Full, not blown, glass, processed under heat by modeling a block of glassy mass applied over the tip of a metal rod. This proeess appears in Murano for the first time in the late 20s on the part of Flavio Poli at the I.V.A.M. furnace of Libero Vitali’s where he designed the first figures in full or “massello” glass.
Once an initial diffidence on the part of the more traditional critics was overcome, who saw in this technique a betrayal of the most traditional feature of Murano glass, i.e., its lightness, this process was widely adopted throughout the island. Once it became one of the most commonly used systems it attained very considerable artistic results, as shown by some work executed by Archimede Seguso and by Alfredo Barbini.
