Table lamp - Glass - Spherical glass table lamp in Murano style.

Spherical table lamp made of Murano glass from the 1970s, and this is also a very well-known piece.

Series/model: it is officially called 'LT 327' or more commonly 'Nembo' / 'Tornado' (the version with white and amber spiral decoration on a satin background).
Features that make it immediately recognizable.
Perfect sphere
External satinized glass with bubble inclusions (pulegoso) and white/amber spirals originating from the center and wrapping around.
• Metal base in chromed or nickel-plated metal (here it is barely visible at the bottom)
It is the 'light' variant of the same family as the previous one, but with a satinized white-milk background instead of transparent amber.
