Scavo means 'dug up' and imitates ancient objects in the form and texture to those found in archaeological excavations.
During manufacturing, a mixture of several powders (carbonates nitrates, talc, silica, etc.) is dispersed on the glass surface. Then the object is heated up to 800-Celsius degrees. This creates an effect of transparency and colour. A second heating creates a unique surface texture.
Alfredo Barbini and Cenedese invented this technique in the 50s. Later, in the 70s, the technique was taken up by Seguso Vetri d'Arte in a series that was designed by Giovanni Patrini.
