The end faces of the mouth and cover should be smooth and free from ups and downs, and the fit should be close, without traces of sandpaper or file polishing. There should be no cracks and peeling all over the body. If there is, it is also defective, and the price is at least one third lower.

The teapot can be opened in three steps: awakening, moistening and airing.
To wake up the teapot, simply put, after we clean it, we directly remove the lid of the teapot and put it in the pot, then add purified water to boil it and cook it for about 30 minutes. It should be noted here that the boiled teapot should never be washed directly with cold water.
To moisten the pot, all pot friends can understand that they want to soak. Put a large number of tea leaves into the awakened teapot, then pour boiling water, and finally cover it and let it stand for 3-5 hours.
Hanging the teapot is to clean the teapot we have treated with pure water again, then wipe it gently with a dry rag, and then treat it once according to the simple pot opening method we mentioned above, and the whole pot opening process is completed.
