What is the principle of this "color-changing" purple clay pot? Is its material safe? Can it be used to make tea? We're going to talk about these issues.
Analyzing this "color-changing" mechanism, experts say that this is achieved by adding "temperature-sensitive materials" to the purple clay pot. The so-called thermosensitive materials are a class of materials that are sensitive to temperature and can change color. At present, there are two main types of temperature-sensing materials on the market: one is directly mixed into the body material; The second is to apply it to the outer surface of the pot body. In either case, the color of the pot can be reversed by sensing changes in water temperature.

Although the application of this material can bring visual impact, some pot lovers say that it has certain health risks. Some unscrupulous businesses may use industrial-grade temperature-sensitive materials, and it is uncertain whether long-term exposure to such materials will have an impact on human health. Therefore, experts recommend not to use this "discolored" purple clay pot to make tea and drink, so as not to cause potential harm to the body.
In fact, in the real high-end works of the purple sand industry, it is very rare to see the use of this material and technique. Some senior craftsmen believe that this practice of only focusing on external visual effects is "ruining" the natural material of purple sand. The charm of high-grade purple sand should be based on its natural texture and unique craftsmanship, rather than relying on these seemingly novel materials and techniques.
But we should also see that the popularity of this "color-changing" purple clay pot reflects the aesthetic needs of some consumers for novelty and excitement. Most of these color-changing materials are chemical products, and the temperature-sensitive color-changing inks also contain certain chemicals. If it is added directly to the mud of the pot, there is a certain risk to health. Even if it is only sprayed on the surface of the jug, long-term contact can be hazardous.
At present, the supervision of such materials in China is not perfect enough, and some unscrupulous businesses may use inferior or cutting corners for gimmicks, which brings hidden dangers to the health of consumers. As consumers, we can't afford to take it lightly.
