To work thin sheet transparent celluloid into different shapes, it is pressed with heat in a hydraulic or other press or mould, and allowed to cool gradually. A French recipe for non-inflammable celluloid consists in dissolving ordinary celluloid in acetone in about the proportion of 25 grammes of celluloid to 250 grammes of acetone, and dissolving pulverised magnesium chloride in alcohol in the proportion of 150 grammes of alcohol to 50 grammes of magesium chloride. Then mix the two solutions so as to obtain finally a pasty mass, containing, say, 20 grammes of the magnesium chloride for each 100grammes of the celluloid. An uninflammable material, similar to celluloid, was invented in 1896 by Cadoret, of Paris, which he claims to be a substitute for indiarubber, celluloid, leather, oilcloth, linoleum, mother-of-pearl, tortoise-shell, amber, ivory, etc., and which is capable of being moulded, drawn, or made into threads, aud in the form of plates, tubes, and cylinders, or soft and silky threads resembling silk in appearance, and can be dyed in various colours. It has another peculiarity - that while the dies or rolls are cold, there is no polish on the surface of the rolled sheet or moulded article, but with heat and pressure the polish of the mould is given to the pressed article.
This material, to which the name of "textiloid" has been given, can be made as transparent as glass.
