A method for the production of ceramic oxide lakes, comprisingthe steps of: (i) preparing a colloidal foam by blowing a gas intoan aqueous solution comprising a precursor salt of said ceramicoxide flake and a surfactant; (ii) precipitating flakes of saidprecursor salt in said colloidal foam; and (iii) dry and calciningsaid precipitated flakes to produce said ceramic oxide flakes.
