The boundaries of the region corresponding to kaolin samples from the Zhuravlinyi Log deposit in the MKO L*A*B* colorimetric system are determined. It is shown that a discriminant analysis makes it possible to interpret the color formation processes in kaolin after it has been worked at different temperatures as well as to evaluate the contribution of variables—color coordinates—in the dominant processes in each heat-treatment interval. A procedure is proposed for identifying the latent (hidden) component of the coloring power of iron compounds in the kaolin. Multidimensional gradation of kaolin samples with respect to whiteness and yellowness according to quality categories is performed.
