Product news: these lamps by Nendo are made by pressing a glass tube to create a narrow gap that clamps the light source in place.
A suspension version hangs from the pinched section, while the light source of the floor lamp balances in the fold.
In Milan earlier this year Japanese studio Nendo launched a series of glass vases with surfaces resembling patchwork quilts and teamed up with Italian designer Luca Nichetto to create a range of products including a scaly carpet and a knitted room divider.
Here's a short description from Lasvit:
Press Lamps, created by Nendo for Lasvit in 2012 are pure and minimalistic and are all hand-blown by Lasvit’s glass masters. Each piece is uniquely formed, and represents a brand new and unusual technique in hand-blown glass.
Cylindrical swing lamps and free-standing lamps twisted at the light bulb’s entrance. The Press Lamp design is available in two types: a pendant lamp and a floor lamp.
In this design, glass tubes are pressed as though they have been pinched, and the light source is fitted into the narrowed space that results. Unusual in the fact that it does not rely on a metal form, the compression of the glass produces a soft, organic form and imbues each lamp with a singular appearance.
