Phantom glass floor tile is a kind of bright brick, which is made by polishing the surface of the brick body. Ceramics with water absorption less than 0.5% are called vitrified bricks. Polished bricks with water absorption less than 0.5% are also vitrified bricks (only polished bricks are not vitrified bricks if they are higher than 0.5%). Then vitrified polished bricks can be obtained by mirror polishing. Because of the low water absorption, their hardness is relatively high and they are not easy to scratch.Phantom glass floor tiles; glazed tiles, commonly known as glass floor tiles, is a kind of bright brick made by polishing the surface of brick body, which belongs to one kind of brick body.
