Invero Ceiling Lamp by Artemide. A contemporary interpretation of the 19th century Zanfirico glass-blowing technique yields Invero, an optical, thermal and technological machine with a distinctly handcrafted dimension. Glass rods are bundled and heated until soft, then attached to 2 pontils and elongated by drawing the softened glass. Horizontal, alternating stripes of white or blue glass are created on the transparent surface transforming a decorative body into a screening element for diffusing LED light. Invero Ceiling Lamp by Artemide are designed by Carlotta De Bevilacqua.
