Particular Murano glass wall sconce from Mazzega. The particular structure allows it to be composed in different shapes or even to create 3 different points of light. Structurally, it consists of 3 electrically separable and independent metal bars, each equipped with two light points; each light point has a curved transparent glass underneath (cm 14 x 12 see photo), and a beautiful glass cover, transparent with shades tending to gray (cm 32x18.5). The three metal bars can be joined together through a system of screws and bolts; the different holes allow you to join them in the shape you prefer, or to separate them and have three distinct but equal points of light. This double Murano glass wall sconce radiates a warm light, and can be used horizontally or vertically on the wall or ceiling, thus offering a variety of options. Made in Italy in the 1960s/1970s.
