Yixing clay is a type of clay from the region near the city of Yixing in Jiangsu Province, China, This clay has been used in Chinese pottery since the Song dynasty (960–1279) when Yixing clay was first mined around China’s Lake Tai. The finished stoneware, which is used for teaware and other small items, is usually red or brown in colour. Also known as Yixing zisha (宜兴紫砂) ware, they are typically left unglazed. The best-known wares made from Yixing clay are Yixing clay teapots, tea pets, and other teaware.
Yixing teapots are usually intended for Oolong teas. A famous characteristic of Yixing teapots is their ability to absorb trace amounts of brewed tea flavors and minerals into the teapot with each brewing. Over time, these accumulate to give each Yixing teapot its own unique interior coating that flavors and colors future brewings. It is for this reason that soap is not recommended for cleaning Yixing teapots, but instead, fresh distilled water and air drying is preferred.
宜兴紫砂茶壶通常用于乌龙茶。 宜兴紫砂茶壶的一个特征就是每次用来泡茶时，它都能将微量的茶味和矿物质吸收到茶壶中。 随着时间的流逝，这些积聚起来的的茶味和矿物质会为每个宜兴茶壶提供独特的内部涂层，为未来的品茗增添风味和色彩。因此，我们不建议使用清洁剂清洗宜兴制砂茶壶，而是使用清水清洗然后让它自然干。
