Glass made in this technique has a spongy appearance, it looks like foamed up.
It contains many air bubbles and appears to be particularly light and transparent.
The inventor was Napoleone Martinuzzi. He used this technique at Venini & C. in the 20s for the first time. During this time, many stories circulated among the tourists about the manufacturing method of this glass, which reported on the most extraordinary substances that had to be added to the glass in order to achieve such an effect. The truth is that you add salts to the glass (generally sodium carbonate or bicarbonate), to avoid mainly the forming of bubbles.
Pulegoso glass embodies the Novecento style that was in fashion in the 30s. The company A.VE.M., Vetreria Artistica Barovier & C., Seguso Vetri d'Arte, etc. produced vases, figurines and the famous cactus. In the 50s, Dino Martens designed the series 'pittorici' for the manufacture Aureliano Toso.
