- Listen to the sound
When you flick the high-temperature tableware with your hand, the sound of high-temperature ceramics is crisper and closer to the sound of metal, while the sound of low-temperature ceramics is duller and has a lower density.
- Water absorption rate
Ceramic products have a certain ability to absorb and penetrate water. If the water cup absorbs and penetrates more, it will expand to a certain extent, resulting in cracks, easy to have odors, and difficulty in cleaning. Therefore, the lower the water absorption rate, the better. The water absorption rate of high-temperature tableware is less than 0.2%, which is easy to clean, and there will be no glaze cracking or local leakage. Low-temperature porcelain has a higher water absorption rate
