Coffee Blackthough little known and not on sale, has been strongly recommended by Bouvier as one of the best blacks that can be used. Soft without being greasy, light, almost impalpable, even before being ground, it gives tints of a very bluish gray when mixed with white, a quality precious for making the blues of the sketch, and dull greens. It is said to dry better than blue or vine black, and to combine admirably with other colours. De Montabert prefers calling it Coffee Brown, giving it as an exemplification of a bluish-brown, but probably this brown hue is owing to want of skill in its manufacture. We have not had personal experience of the colour, but there is no theoretical reason why a carbonaceous black should not be produced from coffee. The mode of proceeding is to calcine the berry in a covered vessel, and well wash the resulting charcoal with boiling water by decantation. In order to prevent the powder, which is of great lightness, from floating, it is made into paste with a few drops of alcohol before adding the water. Next: Frankfort Black Previous: Bone Black
