Abstract
4202. Marx, F. Feb. 27. Lithographic stones, artificial.-Relates to the manufacture of artificial stone free from pores, and specially adapted for lithographic purposes. The materials employed are finely-ground calcium carbonate (marble or limestone), and burnt magnesite, together with a solution of magnesium chloride. In certain cases the burnt magnesite is re-converted into carbonate by means of carbonic acid. The commercial magnesium chloride is purified by exposing the solution to the open air for 10 or 12 days, whereby the sodium chloride, magnesium sulphate, &c. crystallize out, and the clay &c. are deposited. The dry materials are fed into the drum a through the funnel b, and the solution of magnesium chloride is placed in the vessel f. The drum contains mixing and grinding balls p, which are prevented by a grating e from passing out when the materials are discharged. The drum is closed, and the air is partially exhausted by a suitable appliance n. Liquid is admitted from the vessel f, and the pipes are disconnected and the drum rotated. A mould l is placed in a casing h, which is exhausted by an appliance m so as to produce a still greater vacuum than that in the drum a. Communication is established between the drum and the casing h, the materials being transferred to the mould l, which can then be removed from the casing. The stone is allowed to solidify in the open air
