How to distinguish high-quality tiles

No, the whiter the blank, the more zirconium silicate will be added. Excessive addition of zirconium silicate will lead to an increase in radioactive content. High whiteness elutriation mud also has whitening effect, but the effect of 10 times elutriation mud can reach 1 times of zirconium silicate, and the purification process of elutriation mud is complicated, which makes the cost of ceramic tiles soar. It is suggested that you should not blindly pursue whiteness when buying ceramic tiles.

Crisp and loud

Pick up the porcelain and tap it gently to see if the sound is crisp, loud and pleasant. If so, it means that it is high-quality porcelain made of porcelain clay, with good quality; If the sound is heavy or even hoarse when knocking on porcelain, it is porcelain made of inferior porcelain clay, and its quality is very poor, even cracked.

Complete and unified

The patterns on ceramics or carvings should be complete, uniform, clear and firm, and the decorative gold and silver lines outlined should be uniform in thickness, bright and beautiful, which can't be wiped off even with a handkerchief. Monochrome products should be uniform in color and consistent in color. There will be no obvious defects, such as dirty color, lack of glaze and bubbles.
