The Union Porcelain Works, Greenpoint, N. Y., are, it is understood, the only manufacturers in the United States of what is known as hard vitreous porcelain. Their electrical goods are of the same vitreous nature. Others, it is claimed, are more or less open porous bodies, with a soft glaze, which cracks and allows water to be absorbed. Wires cutting; or rubbing against such porous insulators become worn and rough, and the wires break, leading to delay, expense and accidents. There was a time three years ago, Mr. T. C. Smith, of the works, says when cheap insulators were in general use, but their vogue has Gone, and the business in insulators worthy of the name is now steadily on the increase.
