Papier Mache. This substance is made from the pulp of paper, or of old paper ground up with size, and moulded into various forms. A mixture of sulphate of iron, quicklime and glue, renders papier mache to a great extent water-proof, and the further addition of phosphate of soda contributes to make it fire-proof. A concise history of the manufacture has been published by Mr. Bielfield.
