EMPIRE CHINA WORKS.

INSULATORS.—The exhibit was of highly vitreous hard rubber porcelain insulators and ware for insulating purposes,—insulator knobs, bushings, cleats, circuit breakers, push buttons, cut-out bases, switch bases, buttons or tips for electric lamps, etc. The goods are liquified by subjection to the operation of baking to a snowwhite heat whereby the ware is made non-conductive throughout and becomes the best of hard porcelain whether glazed or unglazed. This porcelain ware was in use in the Exposition in the switches and cut-outs furnished by the Bryant Electric Company of Bridgeport, Connecticut.
