By pressing the rock debris through high pressure, the surface hardness after polishing is lower than that of the stone, and the water absorption rate is lower and the wear resistance is good. The surface of the whole brick is not glazed, and the material and color of the front and back sides are the same, hence the name. Although there are varieties such as osmosis and whole body bricks, they are relatively inferior to glazed tiles. Most non-slip tiles are all-in-one bricks.
