After buying a new pot, you can rub it slightly with a fine emery cloth, and never polish it with a coarse emery cloth to avoid damaging the skin (some pot authors have already treated it when selling it). Wash the dust on the surface and the ceramic tiles inside with water or cloth first, and then put them into a soluble teapot or boil them with tea. After boiling, the flame will soon turn off. Simmer the pot with waste heat until the tea is slightly cool, and then ignite and boil. Repeatedly, a new pot of soil can be made. After this process is completed, take out the new pot and dry it naturally before making tea. This is not a necessary procedure. In fact, when you get a new pot, you can make tea by washing and boiling it twice.
