Second, the sandy teapot can absorb tea juice, and it will accumulate "tea rust" after being used for a period of time, so the empty teapot will smell like tea when it is filled with boiling water.
Third, it is easy to wash. If you don't use it for a long time, it will inevitably smell. You can make tea with boiling water two or three times, then pour cold water, and then make the same original tea.
Fourth, it has strong adaptability to sudden changes in heat and cold. In the cold winter, the injected boiling water will not burst due to the sudden change of temperature; Moreover, the heat transfer of sand is slow, and it is not hot whether it is lifted or held.
Fifth, purple sand pottery is resistant to burning, and it is not allowed to explode on a warm fire in winter. It is no accident that Su Dongpo made tea with a teapot made of purple sand pottery, and there was a poem "The bamboo stove relaxed the wind and lifted the pot to shout". This is why people who pay attention to tea drinking at all times and in all countries especially like to use teapots.
