"Georgius Agricola gives a minute description of the varieties of the Hæmatite. He says, that the Hæmatite produces the Rubrica—that it is the color of blood—that being ground on the grindstone it yields a red juice, while the Schist (another variety), gives more frequently a yellow juice—that it is found also in iron mines, but more frequently in veins alone ... that the Hæmatite and Schist are produced in many parts of Germany and also in Spain."

"Amatito and Albin were, as I have shown, natural pigments, which required merely to be pulverized to constitute a fine pigment for fresco painting."

Note: One pigment that should be closer to "albin", considering that both come from the mineral hæmetita, is "almagre morado" which was perhaps acquired by Diego Rivera in Spain and employed by him in a burgundy colored shirt in a figure in his fresco located in a stairwell at the San Francisco Stock Exchange Building in San Francisco, California.
