Yixing Zisha is a unique mineral resource in China, also known as "five-color soil," hidden deep in the strata of hillsides, and is a natural pottery clay. Purple clay teaware has enjoyed a high reputation for thousands of years and has unique advantages in 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. Zisha has a dense texture, fine pores, and is breathable without being permeable to water. The natural iron contained in Zisha has a resolving effect on fat. Scientific experiments have proven that purified water boiled in a Zisha cooker becomes weakly alkaline with a PH value of around 7.1 after mineralization, which is beneficial for the formation of a weakly alkaline healthy body. Some trace elements contained in Zisha can also activate the decomposition of lipase. ■ Due to the shooting environment, the color of the photo may differ slightly from the actual product.
