Very high resistance of glaze to scratching

We continuously measure the hardness of our products' glaze using both the national standard ISIRI 3996 and the international standard EN 101. With a Mohs hardness of 5.5, the glaze on Zarin China products is among the hardest of its kind. This exceptionally glossy, transparent, and hard glaze sets our products apart from others on the market. It not only maintains a brilliant and pleasing appearance for many years but also makes cleaning a breeze.
