The Empire China Works, of Green street, Greenpoint, Brooklyn, have issued a new price list of hard porcelain electrical supplies. It illustrates their various specialties and novelties, and gives information as to price, etc. The hard porcelain used by this concern is a very superior material, suitable equally for glazed and unglazed insulators. It is the porcelain allowing the body to be made of the same material as the glaze, and both to be made vitreous in the same heat. It is perfectly non-conductive throughout, and is remarkable for its strength and general applicability to electrical purposes.
