Electrical Notes from Europe

A new process for making an insulator which is said to resemble ebonite has appeared on the Continent. Powdered tan bark is mixed with one-third of sulphur and the whole is heated until the sulphur melts, when the mixture is well stirred and then cooled. It has the form of small, black grains. These are put in a pressure mold and heated from the outside; this gives a block or a piece of insulating material of any form. The new insulator is said to possess many of the properties of ebonite.
