Robert Pierini, Flacon ZT5, 1995 This exceptional flacon represents the pinnacle of Robert Pierini’s mastery of mouth-blown glass, created at his celebrated atelier in Biot, on the French Riviera. Born in 1950 in Toulon, Pierini apprenticed at the Biot glassworks under Eloi Monod before establishing his own independent workshop in 1980 within a historic olive oil mill, where he pursued his artistic research into the unique properties of glass. The ZT5 flacon is a bold, voluminous vessel of near-spherical form, its clear crystal body encasing a swirling interior world of deep greens, cobalts, teals, and vermilions — colors suspended in graceful motion, as if captured mid-flight. In the 1980s, Pierini reintroduced the technique of glass blown with the cane, developing an elegance of color, shape, and graphic motif that became his hallmark. That technique is abundantly evident here: fine filigree threads of black and white spiral through the body, creating extraordinary depth and movement within the transparent mass. The flacon is crowned by a solid blown stopper of matching workmanship, itself a miniature marvel of patterned glass. For Pierini, what matters is not to follow trends but to create a dream in the space of glass — and this piece, signed and dated 1995, embodies that philosophy completely: a unique, collectible work of French studio glass at its most ambitious.
