A fine, white pigment composed of calcium hydroxide, and calcium carbonate. Lime white is produced by the long-term slaking of lime in water or air to form a thick, white, alkaline paste. It was used for fresco painting because it hardens to form a cohesive film without the aid of a binder. Lime white reacts with proteins, such as egg white, or casein, to produce a tough, insoluble film.
