Abstract
26,758. Harrison, G., [Black, W., and Richards, H. S.]. Dec. 4. Stone, artificial.-A natural appearance is given to the surface of artificial stone consisting of sand or particles of limestone or granite united by cement by treating the stone at a temperature of about 80‹ F. with hydrochloric or other acid, and afterwards neutralizing the acid remaining on the surface with sodium carbonate or other alkali. The treatment removes the cement from around the particles of sand &c. on the surface of the stone.
