The teapot in Wu Wencai is really purple sand. Zisha teapot is a traditional tea set in China, with unique shape and good thermal insulation performance. Wu Wencai is a master of Yixing teapot making, and his works have high artistic value and collection value.

Distinguishing the true teapot from the false teapot can be achieved by the following methods:

1, smell: The teapot has a strange or peculiar smell. This pot is a melting pot.

2. Listen to the sound: the lid knocks on the pot. If the pot sounds crunchy, it means the pot is fake. If it's a muffled sound, it means the pot is real.

3, dripping: pour boiling water into the pot and cover the lid. If there are small drops of water on the lid, it means it is true; if not, it means it is false.
