Nowadays, more and more consumers turn to consume food that has been baked in the oven. This results in rising demand for containers that can withstand acute temperature changes. It leads to a research to develop the soil for use in an oven that can withstand thermal shock up to 400 degrees Celsius (most stoneware, porcelain and bone china are produced with a temperature of not more than 200 degrees Celsius). The clay that is developed can be molded and decorated by coating like other ceramic products, but can retain heat for a longer time. Yet it can be decorated with patterns or colours on the outside surface of the container better.
