Historical origin: The sand artifacts in Yuxian County originated 1,000 years ago. During the Ming Dynasty, a local official presented it to the emperor. The imperial doctor found that the medicine made from it could maintain good medicinal properties, so it became famous. Later, after research, it was found that the utensils of this material are extremely breathable. Under the microscope, they are covered with hundreds of millions of pores like sponges, which contain more than ten kinds of trace elements needed by the human body. Brewing tea with it softens the water & preserves the natural properties of the tea leaves. This is unmatched by iron pots & ceramic teapots, & is known as a living tea set! in 2013, it was rated as a national intangible cultural heritage. Production method: It is made by hand through more than ten processes such as rolling, kneading & drying, & is fired at a high temperature of 1400 degrees for 1 hour. Due to the poor viscosity of this soil, about every 10 burnt, only 4 can be kept intact. & because of the complicated craftsmanship, there are fewer & fewer artists making tea sets, which is extraordinarily precious. It is not only a set of tea sets, but also a piece of art worthy of collection.
