A method for calibrating an apparatus for measuring shape factor is provided, wherein the method comprises determining aspect ratios for each of a plurality of kaolin samples and measuring the shape factors of each of the plurality of kaolin samples using the apparatus, wherein each of the kaolin samples includes potassium oxide in an amount less than about 0.1% by weight of each of the kaolin samples. The method further includes calibrating the apparatus based on a correlation between the aspect ratios and the shape factors.
