Abstract

The object of the invention is to provide a method for the treatment of all kinds of clay or any ceramic composition based on clay. The method consists in distributing in the clay metal ions capable of forming the corresponding oxide at a temperature at the most equal to the firing temperature of the clay thus treated, by maintaining the clay in contact with a liquid phase under conditions such that said ions pass at least in part into the liquid phase and a diffusion of said ions throughout the mass of clay is ensured.
