Cennino Cennini "Il Libro dell' Arte" - "This color is good in secco, with a tempera of yolk of egg, for making trees and foliage, and for laying in.
This color is rather coarse by nature, and looks like fine sand. For the sake of the color, work it up very, very little, with a light touch; for if you were to grind it too much, it would come out dingy and ashy color."
