In 1966-67 Angelo Mangiarotti designed the "Lesbo" and "Saffo" lamps for Artemide, featuring lampshades in organic shapes of handblown Murano glass with graded opaque shading that softens the light they cast makes them cast. In 1967 Vetreria Vistosi entwirft Angelo Mangiarotti designed "Giogali", a lighting range for Vetreria Vistosi. They are ceiling lamps, some of them pendent, made of several horizontally arranged metal rings into which bent glass loops are hung to create a dense, reticular fabric of transparent glass.
In the late 1960s, a curtain of glass rings hooked into each other created a room divider.
