Glazed polished porcelain(600*600) :

The glaze on these tiles is mechanically polished to a super-high gloss or mirror-like finish. Glazed polished porcelain tiles have the advantage of looking like polished porcelain tiles, but they don’t require any sealing. Glazed tiles are subjected to a second firing process where they are covered in a protective coating of liquid glass. This protective coating makes the tiles somewhat slick but also allows them to be printed with a wide variety of designs and colors using inkjet technology.
