kaolin clay brightness

Kaolin Al2H4O9Si2 - PubChem

In general, the higher the brightness of the kaolin the more value the kaolin has. Standard brightness values are measured at a wavelength of 457 nm, and a common standard against which the samples are compared is smoked magnesium oxide. As a general rule, filler clays have a brightness of 80 to 85%, and paper coating clays and high-glossing paint clays have a brightness
