    摘要： The invention relates to a new process for colouring ceramic materials by using aqueous solutions of chromophore ions. In particular, certain types of silica are added to the ceramic mixes which are to be coloured, 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.

    摘要翻译： 本发明涉及通过使用发色团离子的水溶液着色陶瓷材料的新方法。 特别地，将某些类型的二氧化硅加入要着色的陶瓷混合物中，之后将含有Fe（II）和/或Fe（III）的无机盐或Fe（II）的有机衍生物和 /或Fe（III）施加到所述含添加剂的陶瓷混合物的表面。
