Very nice lamp in Murano Pulegoso glass by Carlo Nason for AV Mazzega in the 70′s. The cup rests on three brass plates. The typical Murano Pulegoso glass technique consists of a transparent glass containing thousands of small air bubbles. That seem to float in the mass. This produces a beautiful visual effect once the lamp is switched on. The dimensions, 20.5″ high and 16″ wide. Thank you for your consideration and let me know if you have any questions.
