Our stoneware (white clay) products are made from technologically modified raw materials. Once removed from forms the dishes are dried and baked at 1000ºC. Baked products are covered with food glaze and baked for the second time at the temperature from 1100ºC to 1150ºC. Due to technology employed in the process of production the dishes are resistant to heat. Therefore they can be used in ovens, microwave ovens and dishwashers. Food in such dishes stays warm for a longer period of time. The dishes, though, cannot be used on open fire or electric cookers. We recommend that sudden temperature changes be avoided as well.
