PCT No. PCT/EP98/00136 Sec. 371 Date Dec. 15, 1998 Sec. 102(e) Date Dec. 15, 1998 PCT Filed Jan. 13, 1998 PCT Pub. No. WO98/31647 PCT Pub. Date Jul. 23, 1998A method for coloring a surface of a ceramic mass to produce a colored ceramic body includes providing a host lattice material composed of a colorless metal oxide compound which crystallizes into one of a spinel lattice or a rutile lattice and which may be water soluble; providing an aqueous coloring solution containing water; a first water soluble compound including a metal ion which is one of a two-valent metal ion or a three-valent metal ion and which colors the host lattice material; and a second water soluble compound including a metal ion which is one of a five-valent metal ion or six-valent metal ion and which provides electrostatic balance; generating a mixed-phase pigment in the surface of the ceramic mass by one of (i.) working a fine powder of the colorless metal oxide into the ceramic mass and applying the aqueous coloring solution onto at least one surface of the ceramic mass, or (i.i.) adding a water soluble colorless metal oxide compound to the aqueous coloring solution in an amount effective to form a mixture having a preselected viscosity and applying this mixture to the surface of the ceramic mass; drying the solution; and firing the ceramic body at a temperature ranging from 300 to 1400 DEG C. for a duration ranging from 0.5 to 5 hours.
