Look at the color: the color is red, very bright. This is because non-legal pot makers use inferior sand mud in the production process, and inferior sand mud often presents uneven color in the refining process. In order to cover up this unevenness, they added various chemical additives to the inferior sand mud to make the pot look particularly bright and beautiful after it was finally made.

Listen to the sound: When selling teapot, some vendors often beat the pot body with the lid and make a crisp sound to prove the quality of teapot. This method of listening to voice identification is completely nonsense. The more a teapot makes a clear and loud sound when it is knocked, the more likely it is to be a garbage pot.

Touch the pot body: the garbage pot feels very delicate and smooth, and sometimes it gives off light. This is because such pots are often mechanically polished during processing, and even some profiteers smear cooking oil or shoe polish on the pots to deceive consumers.
