Purple sand cup is a container made of purple sand mud as the main raw material.
Purple sand is a kind of stoneware, a ceramic product between pottery and porcelain. It is characterized by compact structure, close to porcelain tire, high strength, fine particles, shell-like or stony fracture, but it does not have the translucency of porcelain tire. The fetal quality of Yixing purple sand ware has this characteristic, the surface light of the ware is quite flat, with small particles changing, showing sand-colored effect.
The raw materials of purple sand mud are mainly divided into purple mud, green mud and red mud, commonly known as "enriching the people". Because it is produced in Yixing, Jiangsu, it is called Yixing Zisha. Because purple mud has special plasticity, non-adhesion and strong endurance, it creates very favorable conditions for pot makers. When it is burned in the pot, it will be hot and cold at will and will not explode. Even if the pot is filled with boiling water, it won't burn your hands. When making tea, the fragrance of tea can be kept unchanged, and it can be stored in midsummer.
Purple sand is a unique mineral resource in China, which is hidden deep in the mountainside. As the first choice for cooking and making tea in China, Zisha pottery has a history of more than 65,438+0,000 years. It is a perfect combination of practicality and artistry, and has always been loved by literati. There has always been the praise of "the world is full of pearls and jade, why is it like a pill of soil in the west of Beijing" and "the price of soil and gold is competitive, and the world is getting more and more beautiful"! Purple sand not only does not contain any harmful substances, but also is rich in many minerals beneficial to human health. When firing purple sand, it does not need to be matched with other raw materials, so it is not polluted by other external sources. It can burn natural purple sand color by mixing various proportions of purple sand mud, without glazing at all, thus making it a 100% pollution-free cooking utensil. Purple sand is rich in iron and contains many trace elements needed by human body. Therefore, it can decompose the fat in food, reduce cholesterol, and play a wonderful role in health care and disease prevention, preventing premature aging caused by excessive intake of aluminum ions, Alzheimer's disease, children's intelligence, and women's slimming and beauty. Purple sand ware emits far infrared rays when heated. Far infrared rays can activate water molecules and, together with trace elements precipitated from purple sand, mineralize water into mineral water. Scientific experiments have proved that far infrared rays can assist the mineralization of pure water. After boiling pure water in a purple clay pot, it will mineralize into weak alkalinity with a pH value of about 7. 1, which is beneficial to the formation of weak alkalinity and healthy physique. At the same time, far infrared rays can also activate lipase, and some trace elements contained in purple sand can also actively decompose lipase, so the food cooked in purple sand pot is soft but not greasy. The microporous structure of purple sand can also keep the food fresh and make the food "stay in summer without deterioration"!
