Artificial India Rubber


A cheap and useful substitute for Indian

rubber is prepared by mixing a thick solution of Glue with Tungstate of

Soda and Hydrochloric Acid. A compound of Tungstic Acid and Glue is

precipitated, which at a temperature of 86 degrees to 104 degrees F. is

sufficiently elastic to admit of being drawn out into very thin sheets.

On cooling this mass becomes solid and brittle, but on being heated is

again soft and plastic. This new compound can be used for many of the

purposes to which rubber is adapted.
