1. Look at the surface of the teapot. Is it polished or not? Industrial pottery usually has a shiny glaze, while natural purple clay usually does not have any glaze on its surface.
2. Tap the body of the pot with your fingers and listen for the sound it makes. Industrial pottery usually has a high-pitched sound when tapped, while natural purple clay usually produces a more mellow sound.
3. Check to see if there are any markings on the bottom of the pot. Industrial pottery often has a stamp or symbol that indicates it was mass produced, while natural purple clay pots typically do not have any identifying marks.
4. Examine the shape of the pot carefully and compare it with known examples of industrial and natural purple clay pots. Natural purple clay pots are typically more irregular in shape than mass-produced ones, as they are handmade without molds being used in their production process.
The color of the pot body is reddish and unusually bright.

2. The sound made when the lid and body of the pot are struck is particularly crisp and loud.

3. The pot body feels particularly smooth and delicate, and it has a glossy shine.

Collector expert Zhang Xumeng told reporters that when observing a purple sand pot, the first thing to look at is the color. These three pots have one obvious feature, which is that the color is slightly red and very bright. This is because illegal potters use inferior sand in the production process, and inferior sand often shows uneven color in the refining process. In order to cover up this unevenness, they add various chemicals to the inferior sand. In this way, when the pot is finally made, it will appear particularly bright and beautiful.

Next is listening to the sound, some vendors often tap the pot body with the lid when selling purple sand pots in order to produce a crisp sound to prove the quality of purple sand pots. This method of listening to distinguish is completely nonsense. The more crisp and loud sound when tapping, the higher possibility that the purple sand pot is “garbage pot”. Again, when touching it with your hands, you will find that the “garbage pot” feels very delicate and smooth, and sometimes even gives out a bright light. This is because these kinds of pots often go through mechanical polishing in the processing process, and some unscrupulous merchants even apply edible oil or shoe polish on the pot body to deceive consumers.
