Spun and extruded aluminum, blown glass. With Pier Giacomo Castiglioni. A shallow aluminum dome, enamelled with white heat-proof paint, is positioned on top of a deep glass bowl and becomes the reflecting screen of the table lamp. An incandescent bulb is hidden inside the metal base, which is corrugated to better disperse the bulb's heat. The glass bowl, which rests unattached on the base, moves to adjust the light's direction.
Achille Castiglioni said of Taccia in a 1970 interview: "We consider it the Mercedes of lamps, a symbol of success: perhaps because it looks like the shaft of a classical column. We certainly weren't thinking of prestige when we designed it. We just wanted a surface that would stay cool." Taccia was devised in 1958, designed and prototyped in 1959 and, after several years of study of the prototype by Flos to devise a mass production scheme, produced in 1962.
