Pair of round bubble ceiling lights, amber and iridescent, wrought iron structure, vintage 50s

Pair of vintage cut glass ceiling lights, round in shape. The bubble effect gives it its originality. Round shapes bring it both softness and warmth. They can be used as a wall or ceiling. They are original and coquettish. We can imagine them near a main entrance, under a porch, in decoration in the house. For the record: the iridescent appearance visually characterizes the chemical process of degeneration undergone by ancient glasses that have long stayed underground. This iridescence can be deliberately provoked for decorative purposes and in this case consists in coating the glass with a very thin layer of metallic substance.
