According to scientific analysis, the purple clay pot does indeed have the function of preserving the original flavor of the tea soup. It can absorb the tea juice and has the characteristics of being resistant to cold and heat. In summary, purple clay ceramics have five major features:
First, purple clay ceramics are made from sand hammering, which neither takes away the fragrance of tea nor gives off a cooked taste, so it is used to brew tea with all its color, aroma and taste.
Second, the sandy teapot can absorb tea juice. After using it for a period of time, "tea rust" can accumulate, so even boiling water is poured into an empty pot, there will be tea fragrance.
Third, it is easy to wash. If not used for a long time, it may develop an unpleasant smell. You can soak it in boiling water two or three times, then pour out the cold water, and the original flavor of the tea remains unchanged.
Fourth, it has strong adaptability to sudden changes in temperature. Even in the cold winter months, when boiling water is poured into it, it will not crack due to sudden temperature changes; moreover, the sand material conducts heat slowly, so whether you lift, hold or grasp it, it will not burn your hands.
Fifth, purple clay ceramics are heat-resistant. In winter, when placed over a low fire to boil tea, the pot is not easy to burst. When Su Dongpo used a purple clay teapot with a handle to cook tea, he wrote the poem "Pine wind bamboo stove, calling each other with the pot", which was certainly no accident.
This is the reason why people who care about drinking tea at home and abroad especially love to use purple clay pots.
