Gaiwan bottom inscription (Fired by Qianshu Ancient Dragon Kiln Yongbing) Lotus cup bottom inscription (Ancient Dragon Kiln) The Qianshu Ancient Dragon Kiln is located in Niujiaoshan, Dingshu Town, Yixing, Jiangsu. It was first fired in the Ming Dynasty and has a history of over 600 years. It is one of the only remaining Ming Dynasty ancient dragon kilns in China, known as a "living dragon kiln" and the "last Ming Dynasty ancient kiln in Yixing." It is built based on the mountain's terrain and uses wood-firing techniques to fire ceramics. It holds significant historical, cultural, and intangible heritage value and is a key cultural heritage protection unit in China. The characteristics of Zisha wood-fired pottery are natural, ancient, and unique. The burning of wood creates natural ash glaze and fire marks, resulting in rich colors and luster, and a rough yet warm and moist texture. Its porous structure is unique, purifying water quality, softening the tea liquid, and enhancing the tea's flavor. It can form the charm of "one color entering the kiln, ten thousand colors emerging from the kiln." Unlike the smooth and uniform surface of electric-fired teapots, every 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." It is deeply hidden in 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 beneficial natural iron 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 can affect human health. Zisha has a dense texture with fine pores and is breathable without being permeable to water. The natural iron in Zisha has a resolving effect on fat. Scientific experiments have proven that purified water, when boiled in a Zisha cooker, becomes weakly alkaline with a PH value around 7.1 after mineralization, which is beneficial for forming a weakly alkaline healthy body constitution. ■ Due to the shooting environment, the color of the photo may differ slightly from the actual product.
