Consider such a material as porcelain stoneware - it is an artificial stone made using burned clay. By the name of this material, it can be confused with natural granite, but it is, but they have a difference besides the fact that granite is natural material and an artificial porcelain tile. Porcelain stoneware is made so that the adhesive solution is not absorbed into its structure in contact with porcelain tiles and does not change its shade over time, which you can’t say about the use of granite.
