Porcelain stone and kaolin have different ingredients and origins so that they have different methods of quarrying and processing. 瓷石与高岭土的矿物成分不同,成因有别,在开采和加工方法上也有区分。
When porcelain stone is ground to fine powder, potters block the flow of water gates to stop the water-powered trip-stamper. 瓷石舂细后,陶工用闸板截挡住水流,使水碓停止运转。
