1. Look at the color. The color mentioned here mainly depends on the color of the carcass of the bone china tableware that does not cover the flower surface. The bone china with high bone char content should be milky white or milky white. Bone china is not as white as possible, natural milky white is good bone china.
2. There are two ways to listen to the sound. The first is to hold the bone china tableware in the palm of one hand, and the other hand bounces off the edge of the bowl of the bone china tableware. The sound of good bone china tableware is as clear as a bell, and the longer the sound, the smoother the carcass and the better the quality of the porcelain. The second is to inject about one-third of the water in the bowl. One hand dipped in some water will make a “chirp” resonance sound along the side of the bowl. The bigger the bowl, the more obvious the effect.
3. Touch the bottom of the bowl of bone china tableware, why should you touch the bottom of the bowl of bone china tableware? Because of a bowl with fine workmanship, the bottom of the bowl needs to be polished twice, which is not only slip-resistant but also prevents scratching the tabletop. This is the process of testing a porcelain from the details.
