A species of steatite. It imparts to the touch a peculiar unctuous feeling, like fine white soap. The soap-stone of this country is chiefly obtained from the Lizard, in Cornwall, where it is found in connexion with serpentine, to which it is nearly allied. It is much used in the manufacture of porcelain; also for polishing marble and other stone. It is the basis of various cosmetics, and is combined with carmine to form rouge; it is also found very useful in taking grease spots out of silks, stuffs, etc.
