At our factories in Portugal, ancient skills of modelling and decorating are combined with modern technology in a special process that produces high-quality fine stoneware products capable of withstanding everyday use over many years.
Manufactured in a single fi ring system heated up to 1180 ºC (2160 ºF) our stoneware is very strong and durable. Its glazed surface is fully vitrified which gives it high resistance to both thermal and mechanical shocks.
In partnership with the University of Aveiro (Portugal), and with the goal of making stoneware even more sustainable, we developed Ecogres®. This new raw material, made from waste generated by Grestel's own production processes along with waste from nearby industries, is completely innovative.
