How to distinguish the quality of teapot. And good or bad?

1. Touch by hand: Although a good teapot feels frosty, it won't feel particularly prickly. The real teapot's graininess is a very slight feeling.

2. Weighing: The teapot is made of purple sand, and the density of purple sand is relatively high, so the quality of the teapot will be relatively light, and it will feel lighter than ordinary pottery pots when you weigh it by hand.

3. Listen to the sound: the knocking sound of a really good quality teapot is not so brittle, but a little boring, so you should knock it with your hand when buying a teapot.
