Its manufacturing material is Zisha clay, and its origin is Dingshu Town, Yixing, Jiangsu, hence the name Yixing Zisha. It has a perfect combination of artistry and practicality, and with the added benefits of brewing tea, tea zen, and the culture of single-mindedness, the works of famous masters are often impossible to obtain even one teapot, truly reflecting the saying, "What is lacking in human jewelry, Yixing Zisha is the most essential." Yixing Zisha is a unique mineral resource in China, also known as "Five-Color Earth," deeply hidden in the strata of the mountainside, and is a natural pottery clay. Zisha teaware has a high reputation for thousands of years and has unique advantages when brewing tea. Zisha is rich in natural iron, which is good for health, and is resistant to acid, alkali, and high temperatures. Long-term use of Zisha can avoid excessive intake of harmful metals such as aluminum ions, which affect human health. The texture of Zisha is dense, the pores are delicate, and it does not allow water to penetrate. The natural iron contained in Zisha has a resolving effect on fats, and scientific experiments have proven that after purified water is boiled in a Zisha rice cooker, the pH value mineralizes to a weak alkaline state of around 7.1, which is beneficial for the formation of a weak alkaline healthy constitution in the human body. Some trace elements contained in Zisha can also activate the decomposition of lipase. Instant purchase OK, thank you.
