at first glance
consumers can choose to carefully observe the reflection on the surface of sanitary products from the side under strong light, and it is better to have no or little sand holes and pockmarks on the surface
products with high brightness index adopt high-quality glaze materials and very good glazing technology, which have good light reflection and good visual effect
second touch
you can rub gently on the surface with your hands, and it is better to feel very flat and delicate
you can also touch the back, and it's better to feel the slight friction of "rustle"
three listening
you can tap the ceramic surface with your hands. Generally, good ceramic materials make a crisp sound when knocked
four ratio
mainly tests the water absorption rate. The lower the water absorption rate, the better
ceramic products have a certain adsorption and permeability to water. If water is sucked into ceramics, it will produce a certain expansion, which is easy to make the glaze of the ceramic surface crack due to expansion
especially for the toilet, if the water absorption is high, it is easy to suck the dirt and odor in the water into the ceramics, and the odor that cannot be removed will occur over time
