∙ fire resistance (melted at 1750-1800 ° C and above);
∙ chemical inertness;
∙ mechanical strength (in the dried and calcined state);

∙ minimum content of dyes;
∙ low abrasiveness;
The color also depends on the mineral composition and the nature of impurities, and may range from blue and white to yellow and gray. The industry uses mainly light-colored, and white kaolin.
