Today, a friend of pottery said that the heat transfer of purple pottery pot is faster than that of other tea making utensils. What is the reason?
In fact, the reason is not complicated, which is mainly determined by the raw materials of purple pottery. Jianshui purple pottery is made of colorful mud produced locally. The raw material is rich in iron. Especially in purple soil, the content of iron is higher.
Purple pottery teapots and teacups made of clay rich in iron are fired at a high temperature above 1100 ℃ after being put into the kiln, and the iron elements in them also undergo a similar process of ironmaking.
The teapot is as hard as iron, and there is a chime when it is struck, which indicates that the iron element in the teapot can be refined into simple iron or substance close to that of simple iron at 1100 ℃.
A teapot rich in iron has good heat transfer performance after being fired. When boiling hot water is added to the teapot, it can be transferred to the whole pot in a short time. In fact, people think that teacups are more hot than other teacups.
What kind of tea is suitable for the purple pottery pot with fast heat transfer and high temperature? This is also a question that many friends who buy purple pottery often ask.
Although different kinds of tea brewing have their own differences, but the overall follow a principle: the more tender and green tea, the lower the brewing water temperature; on the contrary, the higher the water temperature. When the tender green tea is brewed at low temperature, the tea soup is bright and fresh, and the vitamin C in the tea is less damaged; the older tea can be brewed at high temperature, which can fully extract the effective ingredients, making the tea taste moderate.
Green tea is not suitable for brewing green tea at 80 ℃. All kinds of flower tea, black tea, medium and low-grade green tea, oolong tea, Pu’er tea and Tuo tea must be brewed at high temperature. At this time, purple pottery pot is a good tool. Even in order to improve the temperature of the tea, you need to warm the pot before making tea, and you need to pour the pot with boiling water when brewing.
