Our history

The activity of the Batllori-Collet family saga began in 1874 with Josep Batllori i Munné, son of Mariano Batllori i Juvert, a potter from Sants (Barcelona), who settled in L'Hospitalet de Llobregat. For more than a century, quality ceramics for ornamental construction finishes and other utilitarian pieces are manufactured. In the 80’s, because of the structural ceramic products crisis, the activity turned into producing ready-made ceramic bodies, so introducing in the market a quality raw material for pottery that allowed potters to concentrate their activity to produce finished ceramics.

In 1979, the main production activity moved from L'Hospitalet de Llobregat to the new facilities sited in Esparreguera (Barcelona). There started a new phase of productive development that located CERAMICA COLLET and its brand SIO-2® as leader in the manufacture of red ceramic bodies for pottery in Spain. In addition, the development of a new program of clays for Arts & Crafts began. First item was SIO-2 clay in small vacuum packs of 2 kg.
