1. Touch with your hands: Although a good purple clay teapot feels frosted to the touch, it does not have a particularly scratchy grainy feel. The graininess of a real purple clay teapot is very slight. .
2. Weigh the weight: The purple clay teapot is made of purple sand, and the density of the purple clay is relatively high, so the quality of the purple clay teapot produced will be relatively light, and it will feel lighter when weighed by hand. Clay pots are lighter.
3. Listen to the sound: The knocking sound of a really good-quality purple clay teapot will not be so crisp, but rather a bit dull, so when buying a purple clay teapot, you should knock it with your hands.
