Abstract: A process for making tiles comprising: i) mixing the ceramic raw materials; ii) dry-grinding the ceramic raw materials or wet-grinding the ceramic raw materials and spray drying the ceramic slip obtained from the wet-grinding; iii) forming green tiles by pressing the powdery grinded ceramic raw materials obtained from step ii); said process being characterized by the addition to the ceramic raw materials, before step iii), of from 0.01 to 5.0% by weight, based on the weight of the ceramic raw materials (dry matter), of a composition comprising a polymer obtained by polymerization in the presence of a sugar or a degraded polysaccharide.
