Six near white china clays were examined for their colour, following the I.C.I. trichromatic colorimetric co-ordinate system after being fired to come 7 and 13 and the results were correlated with their Fe2O3, and TiO2 contents, determined polarographically. The yellowness factor giving a measure of the off-whiteness of the samples was also calculated. The clay having the minimum purity, maximum brightness and lowest yellowness factor was selected for incorporation in a porcelain composition. Different amounts of Fe2O3 and TiO2 were added to this composition and fired to cone 7 and 13. The fired colour of the samples were similarly examined. It was observed that Fe2O3 imparts colour to porcelain body and its effect becomes prominent in presence of TiO2. In samples comparatively free from Fe2O3, TiO2 has little effect on colour.
