What material is purple sand? Chemical composition? What are the pros and cons of using this to drink water?

Purple sand is often referred to as purple sand pottery and is a branch of pottery. The national standard for "purple sand pottery" defines it as: made of special clay with fine texture and high iron content. , mainly russet in color, hard in texture and unglazed pottery with good air permeability. According to the definition of national standards, the difference between purple sand and other pottery is: 1: Made of clay with a high iron content; 2: Not Glaze; 3: Breathability; Therefore, pottery that meets the above three points is purple clay. At the same time, the product quality must comply with the technical requirements of the national standard "Purple Clay Pottery". The raw material for making purple sand pottery is a kind of hydrated aluminosilicate mineral clay, which is generated by long-term weathering and geological processes of feldspar-containing rocks in the earth's crust. It is widely distributed in nature and has many types. It is found in most areas of China. Rich in quantity, its main ingredients are silica, aluminum oxide, ferric oxide, manganese dioxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide, titanium oxide and crystal water. Therefore, the raw materials for making purple clay pottery are widely available in various regions (some fields are also good raw materials for making purple clay, but they must be approved by the land and resources department). There is no such thing as true or false. Depending on the production of different purple clay pottery products, they can also be used. Adding some of the above-mentioned oxides is what the profession calls the formula. There is no such thing as "chemical material". Since it needs to be fired at high temperatures (usually above 1100 degrees), it is non-toxic and harmless to the human body. Purple sand is a unique mineral resource in China, hidden deep in the mountains. Purple clay pottery has been used as the first choice for cooking and tea-making in China for more than 1,000 years. It is a perfect combination of practicality and art and has always been loved by literati. There have always been praises such as "The pearls and jade in the world are as safe as a pill of earth in Jingxi", and "The earth and gold compete for price, and the world becomes more and more prosperous with each passing day"! Purple sand not only does not contain any harmful substances, but is also rich in a variety of minerals that are beneficial to human health. There is no need to mix it with other raw materials when firing purple sand, so it is not subject to other external contamination. It can be fired into a natural purple sand color by mixing various proportions of purple sand clay without the need for glaze, making it a 100% pollution-free cooking vessel. Purple sand is rich in iron and also contains a variety of trace elements needed by the human body. Therefore, it can decompose fat in food and lower cholesterol. It is useful for health care and disease prevention, and prevents the human body from consuming too much aluminum ions and promoting premature aging, Alzheimer's disease, and children. It has wonderful effects on improving intelligence and slimming beauty for women. Purple clay utensils can emit far-infrared rays during the heating process. Far infrared rays can activate water molecules and, together with trace elements precipitated from purple sand, mineralize the water into mineral water. Scientific experiments have proven that far-infrared rays have an auxiliary mineralization effect on pure water. After the pure water is boiled in a purple clay cooker, it will be mineralized into a weak alkaline pH value of about 7.1, which is conducive to the formation of a healthy weak alkaline constitution in the human body. At the same time, far-infrared rays can also activate lipase, and some of the trace elements contained in purple clay can also activate enzymes that break down fat, so the food cooked in purple clay cookers is soft and not greasy. The microporous structure of purple sand can also enable purple sand cookware to keep food fresh, so that the food "will not go rancid during the hot summer"! It is recommended not to use it as the quality may be poor and long-term use may affect your health.

The purple clay teapot has good air permeability, so the tea made with it will not easily change in flavor and will not go rancid over the summer. If it is left unused for a long time, there will be no residual gas. As long as it is filled with boiling water before use, pour it out immediately, and then rinse it in cold water, the vitality will be restored and the tea will still have its original flavor.

The purple sand pot has good performance in sudden changes in cold and heat. In the cold winter months, when boiling water is poured into the pot, it will never burst due to sudden changes in temperature. At the same time, the sand conducts heat slowly, so it won’t burn when you hold it after making tea. It can also be cooked and heated over a slow fire without cracking due to fire.

Brewing tea in a purple clay pot can maintain the original flavor of the tea, increase the flavor of the tea, and also help tea drinkers cultivate their mind and character. The purple sand itself means certain minerals, which are beneficial to the human body. If you use a purple clay teapot all year round, the tea will become more fragrant the more you brew it, and people will feel more energetic the more you drink it.
