Antoni studied sculpture at the Escola Massana in Barcelona (1975-80) and Advanced courses of iron sculpture in the workshop of Bernard Perrin, in the École National Supérieur des Beaux-Arts of Paris (1982 – 1983). Since 1980 he exclusively worked the sculpture using, in the beginning, iron, bronze, aluminium, stainless steel, zinc and lead as materials. From the 90s, he incorporates polyester resins, plastic thermoforming, painted iron, serigraphs, glasses, mirrors, pictures and objects from his workshop. In his last production colour acquires a substantial presence, with ranges and textures intentionally originate in the industrial world. From the year 2000, these materials are combined and fused together to achieve new plastic qualities. As support of his sculpture, he has carried out an extensive creation of works on paper.
