glossary

Terracotta (Italian = burnt earth) - also written terracotta and referred to as cotto for short - is an unglazed earthenware tile, which is characterized by its natural earthy brown-yellow to brown-red color variants. The origin of this type of tile lies in the Mediterranean area, with the production centers in Tuscany and Emilia-Romagna. There they are still formed by hand today, so that the individual tiles have uneven dimensions. The attraction of terracotta lies in the fact that the surface matures with increasing age, giving it a patina. This is made possible above all by the fact that the open-pored shards can easily absorb liquids of all kinds. As a consequence, however, this also means: a stain remains a stain. In order to avoid excessively undesirable contamination, cotto floors must accordingly often be impregnated with suitable oils and waxes.
