A novel heat shielding material made of an inorganic material is proposed. A heat shielding material made of an inorganic material, including: a base material; a underlayer layered on the base material; and a top layer layered on the underlayer, wherein the top layer has a thickness such that the underlayer is not visually recognizable, and transmits infrared rays, and the underlayer includes a commingled between a material of the underlayer and a material of the top layer, and a main reflection region where the material of the top layer is not present. By a suitable combination of the top layer and the underlayer, a high solar reflectance (TSR) exceeding 30% can be obtained even at an L* of 40 or less.

A method for obtaining a porcelain stoneware tile with anti-slip surface includes an enameling step, said step comprising the depositionon the walkable surface of the tileof a mixture of micro-grits added to a usual enamel, most of said micro-grits having dimensions smaller than 60 m and being in a percentage smaller than 25% and preferably smaller than 20% by dry weight of the mixture, the remainder consisting of enamel.
