Why hard-paste porcelain?
Hard-paste porcelain is fired at the highest temperature, about 1400°C, in the ceramic industry for tableware. It has the hardest glaze because the quartz content in the glaze increases with the firing temperature. Due to the exceptional firing, the porcelain has a pure white body. It is transparent and sounds clear.
Moreover, hard-paste porcelain has a high heat capacity, which keeps food warm for a long time, unlike other ceramic materials.
It is odorless, tasteless, and colorfast. It is resistant to acids, mechanical stress, and does not age. It is fully dense-sintered, meaning the product is 100% waterproof, which results in higher hardness. The glaze only serves to make the product easier to clean. Porcelain is dishwasher safe. Due to the durability and shock resistance of this porcelain, it is often used in hotels and restaurants.
This quality is called hard-paste porcelain.
