Ebonite is formed by the incorporation of sulphur with twice its weight of caoutchouc by means of heat and pressure. As it is hard and takes a high polish it is much used for manufacture of combs, buttons, and other articles, and owing to the fact that it is easily electrified, and a poor conductor of electricity, it is also largely used in the manufacture of electrical apparatus.
