In the hard oxidizing fire iron red glaze which colorated red exposed magnesioferrite and whitlockite-type crystals. And whitlockite-type crystals has formed before magnesioferrite forming in the step of sintering. This study tries to identify the coloration mechanism of hard oxidizing fire iron red glaze by the experiment of substitution of whitlockite-like crystals and to confirm such substitution be able to farm magnesioferrite. As the results of experiment, magnesioferrite was appeared during substitution of two kinds of whitlockite-type. It can be considered that the magnesioferrite colors the iron glaze to red with covering the glaze surface.
