H. C. Fry Glass Company, Rochester, Pennsylvania

CERAMIC SECTION TO HEAR TALK

ON NEW INSULATORS OF GLASS

The H. C. Fry Glass Co., Rochester, Pa., are developing glass insulators to be used on electric transmission lines under high voltage conditions. The glass used is similar to the ovenware glass which this company has had on the market for some time and with which they have had such a great success. They are also making spark plugs using a similar glass.

The glass has the properties of low expansion, high melting temperature and high insulating qualities for the electric current. E. H. Hughes, of the H. C. Fry Glass Co., will give a short talk on the properties of this glass and in general of the requirements of insulators for high tension lines at a meeting of the Ceramic Society to be held (Friday) March 16th, at the Bureau of Mines Building, Forbes Street, Pittsburgh. The meeting will be proceeded [sic] preceeded by a dinner at the cafeteria, and those who do not care to attend this dinner will have an opportunity of participating at the meeting by coming in at about 8 o'clock.

The Westinghouse Electric Manufacturing Co., who manufacture porcelain insulators, will be represented by R. E. Arnold, of their Research Department, who will tell the Society something about the properties and requirements to be met by the insulators that they make.

E. H. McClelland, Technology Department, Carnegie Library, will be at the meeting, and will inform the members where they can find data relating to porcelain and recent practice in insulator design and their testing for high voltage currents.

This meeting should be of interest to ceramists in the glass and porcelain branches, as well as to the electrical engineer and physicist, and the officers of the Society extend a cordial invitation to anyone who may be interested.
