Banko ware is famous for heat resistant ceramic wares such as earthen pot, ceramic plate and so on. Petalite is used as a raw material for these ceramic wares aiming for the enhancement of heat resistant property. Their thermal expansion coefficient is as low as 2.0×10-6 K-1 due to β-spodumen produced from petalite during firing in the body. Heat resistant property is also improved because the porous body is suppressed the spreading for cracks. In addition, the infrared radiation of them is much higher than that of metal wares, which made it possible to heat ingredients efficiently. It is expected that Banko ware with heat resistant and high infrared radiation properties, which are advantages for a kitchenware, is used continuously at the kitchen in the future.
