The characteristics of Zisha wood firing are natural, ancient, and unique. The burning of firewood produces natural ash glaze and fire marks, resulting in rich colors and luster, and a rough yet warm and moist texture. Its pore structure is unique, purifying water quality, softening tea soup, and enhancing the taste of tea. It can form the charm of "entering the kiln as one color, and leaving the kiln with myriad colors." Unlike the smooth and uniform surface of electric fired teapots, each piece is filled with unique marks left by fire and ash. Yixing Zisha is a unique mineral resource in China, also known as "five-colored earth," hidden deep within the strata of the mountainside, and is a natural pottery clay. Zisha teaware has enjoyed a high reputation for thousands of years and has unique advantages when brewing tea. Zisha is rich in natural iron, which is beneficial to 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 breathability that does not allow water to penetrate. The natural iron contained in Zisha has a resolving effect on fat. Scientific experiments have proven that purified water, after being boiled in a Zisha cooker, mineralizes to a weak alkalinity with a PH value of around 7.1, which is beneficial for the formation of a weak alkaline healthy body constitution. ■ Due to the shooting environment, the color of the photos may differ slightly from the actual product.
