, using high-quality natural purple sand seiko ceramic liner, absolutely safe and harmless to human body. Purple sand is a kind of clayey siltstone containing iron, which is composed of hydromica, kaolin, Yingshi, mica and iron. The main chemical components are iron oxide, silicon oxide, calcium oxide, magnesium oxide, manganese oxide, potassium oxide and sodium oxide. Purple sand has been used in cooking and drinking utensils for more than 1000 years. Modern scientific detection and analysis have proved that it does not contain any harmful elements. Some people use metal pots to make soup, such as aluminum, iron and copper. When these metal containers are heated, it is easy to destroy the vitamins in food, change the structure of protein and affect the taste of food. Especially some metal containers, such as aluminum pot, may cause Alzheimer's disease if they are used for a long time, because the acidic amino acids in animals contained in food are dissolved in soup, and people are prone to poisoning after eating. Using purple casserole with almost zero metal content can keep the original flavor of food. Not only that, purple sand is also rich in a variety of trace elements needed by the human body, which can decompose fat, reduce cholesterol content and reduce greasy. There are two ways to make soup in purple sand casserole. There are two ways to make soup: stew without water and stew without water. Usually at home, it is usually stewed without water, that is, the original food is put in a cauldron and then directly heated to make soup; Waterproof stewing means putting food in a small stew pot, putting 80% water in the small stew pot, and then putting the small stew pot in a big pot. At the same time, water should be put in the big pot (the water should not be higher than that in the small stew pot). Both the small saucepan and the large saucepan should be covered and then electrified. The small saucepan should be heated by the temperature and pressure of the steam in the large saucepan. Two 0.7-liter ceramic stews can be placed in the 5-liter and 6-liter ones, and up to six 0.3-liter small purple clay stews (one for each family) can be placed. If you want to stew a big chicken, put it in a big pot. To stew bird's nest, Tian Qi and others must stew it in a small saucepan! The stew soup outside Shaxian snack is heated with purple sand stewed in a small saucepan in this way, which can release far infrared rays beneficial to human body, and all kinds of food will be absorbed by far infrared rays, making the food more fluffy, soft, sweet and delicious. Far infrared ray test experiment 1: Put two pieces of ice with the same size into a metal liner and a purple sand liner with the same area, and you will find that the ice in the purple sand liner melts very quickly. This is far infrared at work. Examples of far infrared rays: Roasting sweet potatoes or chestnuts with hot stones is to use the characteristics that natural sand and gravel can release far infrared rays when heated, which can not only radiate to the surface of the material, but also penetrate deep into the inner layer, so the roasted sweet potatoes and chestnuts will be fluffy, soft, sweet and delicious. Natural bacteriostasis and quality guarantee: purple sand has good air permeability and strong fresh-keeping function. Suitable for eating in summer, and the food should not go bad. Food preservation test experiment: make two cups of tea on a hot day, one in a teapot and one in a glass, cover them all and put them in a place without refrigerator and air conditioning. Three days later, when I opened the lid, I found that the tea in the glass had gone bad and moldy, but the tea in the teapot had not changed its taste, which showed the fresh-keeping effect of purple sand. Purple sand has the functions of activating lipase and decomposing fat, and the cooked food is soft but not greasy, which has the effects of health care and beauty.

The nature of purple sand cookware is very stable, acid and alkali resistant. Does not react with food at high temperature. So the food is nutritious and original. Common sense of life: Chinese medicine practitioners in China always use casseroles for cooking and never use metal pots and pans. Is this just a traditional habit? The answer is no, but because the alkaloids in traditional Chinese medicine can easily react with metal pots and pans when heated, thus changing the medicinal properties of traditional Chinese medicine, making the medicine lose its efficacy and even producing toxic and side effects. The chemical properties of casserole are very stable and will not react with other foods. Purple casserole is a fine casserole in casserole, and there will be no chemical reaction.
