In particular, certain types of silica are added to the ceramic mixes which are to be colored, after which aqueous or organic solutions comprising inorganic salts of Fe (II) and/or Fe (III), or organic derivatives of Fe (II) and/or Fe (III) are applied to the surface of the said additive-containing ceramic mixes.
