I made a couple of these lamps last week at UFACTO. Named "Parabola" and designed by Pierre Charpin, these pieces are made at UFACTO for Galerie Kreo. Kreo represents a smattering of high-level designers, mostly from France, and produces pieces that would usually be impossible to fabricate in a large-volume, industrial manner. This means that the pieces designed for Kreo are usually both quite large (the Parabola stands about 7.5 feet tall, and requires at least that much free wall space to hang) and quite expensive (six digits, in Euros). Kreo consistently has these pieces, especially the molded fiberglass ones, made at UFACTO. Each piece is produced in an edition of 12, and sometimes just 1.
The bell is made of two separate fiberglass shells, glued together at the outer edge and at the center. Quite flexible when separate, the bell stiffens up considerably when both pieces are fixed to each other.
You might not be able to tell from the image of the finished lamp, but the bell and the stand are not attached. Rather, the bell, or shade, is fixed to the wall and the bulb stand is stationed in front of it. Fun fact: the shade of pink was chosen by Charpin to match a faded t-shirt he was wearing while going over the fabrication with David Toppani (master craftsman of UFACTO). The rosy reflected light is beautiful in person.
