Fig.2 shows the appearance of the typical glazes with the iron ore residue and Fe2O3 as the ceramic colorant, respectively.
It can be seen that, the glazes with the iron ore residue had more abundant colors and fancy than the glaze with the Fe2O3. So the iron ore residue was suit for the ceramic colorant of the separative-phase fancy glazes. Furthermore, the phenomenon
of the dry glaze occurred at the edge of glazes when the firing temperature was higher than 1280 C. The color values (a*, b*) and lightness (L*) parameters (whiteness)are listed in Table3.
