Square glass globe for ceiling light or wall lamp

Very nice square globe for ceiling light or wall lamp. The glass, thick, has regular blisters, nested in each other, some are made of smooth glass, others have an orange peel appearance. The rendering is really very nice. The glass is almost colorless, but it seems to me to pull slightly towards yellow green (depending on the light and the environment), but less than in the photos. This globe is in perfect condition: neither shine nor crack, not even scratch! It measures 15 cm side for a height of 10 cm (including collar). The neck or opening measures 11cm of inner diameter and 13 cm of outer diameter (it is this one that is to be taken into account, it seems to me, to find the right support.). It weighs 1060g.
