Another application of ceramics to automotive needs is a ceramic sensor that is used to measure the oxygen content of exhaust gases. Ceramics is the science of pottery which may be defined as the objects made from special type of clay, hydrated aluminum silicate (Al2O3.SiO2.2H2O), feldspar and silicates. The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. The high temperature allows the tiny grains of the individual ceramic components to fuse together, forming a hard, tough, durable and corrosion-resistant product. The clay is fired at relatively low temperatures (1,000–1,150°C), producing a slightly porous, coarse product. Because stoneware is non-porous, glaze is applied only for decoration.
