India Rubber Shoe Blacking.—Raw india rubber is given as a constituent of several shoe blackings. Formulæ are given as below for paste and liquid blackings.

I. Paste blacking: bone-black, 20 parts; molasses, 15 parts; vinegar, 4 parts; sulphuric acid, 4 parts; caoutchouc oil (as given below), 3 parts.

II. Liquid blacking: bone-black, 60 parts; molasses, 45 parts; gum arabic dissolved in water, 1 part; vinegar, 50 parts; sulphuric acid, 24 parts; caoutchouc oil, 9 parts.

Caoutchouc oil is made by dissolving or digesting virgin rubber 55 parts in linseed oil 450 parts.

Waterproof Composition for Boots.—One ounce of virgin rubber cut into pieces is digested in enough oil of turpentine to form a stiff paste. In applying heat take great care lest the contents of the vessel become ignited. When homogeneous, which condition may be brought about by rubbing in a porcelain mortar, as described in chapter XII., it is mixed with 5–6 ounces of boiled linseed oil. This gives an ointment almost of the consistency of butter.
