The Anglo-Saxons referred to chalk as “Hwiting-melu”, literally “whitening powder”. And this was exactly what chalk was used for over the millennia, be it as a white pigment in paints, primers and plasters, or as an extender for other pigments. Wherever paints were being used there was also chalk.

known as rock-builders. Since the fine material of the Chalk is dominantly calcite, our hope that the mode of formation of drewite would afford a clue to that of Chalk has not, for the time at any rate, been realized. The question remains, however, as to whether the fine material of the Chalk was deposited as aragonite, and has subsequently
