Title |
Black Porcelain Super Ignitioniter |
Description |
The object is a black cylindrical porcelain ignition igniter, which tapers towards the top. The top of the igniter is open, allowing visibility into the inside. The top, bottom, and interior of the igniter are all white, with the bottom featuring a small central hole that provides a glimpse of the inner workings. Surrounding this hole, the area is slightly elevated. There is an embossed inscription that encircles the hole on the bottom, reading "SUPER IGNITIONITER. EG." Notably, the "EG" portion of the inscription is upside down, adding a unique detail to the piece. Accompanying the item is a note that reads: "VITREOUS ELECTRICAL INSULATING PORCELAIN. THIS illustrates a railway signal base of 'Nu Blac' body and glazed black. This material was developed in order to meet an increasing demand for a material that could take a good uniform black glaze and have high dielectric and mechanical strength. Many manufacturers are now substituting this material for others because it does not show discolorations due to handling in assembly. This material can be molded as easily as our regular white electrical porcelain. Manufactured by THE STAR PORCELAIN COMPANY. TRENTON, NEW JERSEY. Established 1899." Although the note references a specific porcelain material, this item does not appear to be the same piece discussed in the note. According to the Potteries of Trenton Society and D.V. Abramson and T. Karschner's book An Inventory of Historical Engineering and Industrial Sites, Trenton, New Jersey, The Star Porcelain Company operated in Trenton, New Jersey from 1900 to 2002. The company was known for its specialized manufacturing of electrical porcelain, which led to rapid growth during its first two decades. By the late 1970s, they were still producing electrical porcelain before eventually ceasing operations. According to Reliance Potteries, porcelain insulators are crucial for power transmission systems. Their primary function is to prevent electrical current from leaking or short-circuiting, as porcelain is a non-conductive material. Some advantages of porcelain insulators include their ability to withstand both high and low temperatures, minimal environmental impact when disposed of, and their superior electrical strength compared to polymer insulators. Given these benefits, porcelain insulators remain a reliable choice for distributing electricity safely across power systems. Citations: Abramson, D.V. and T. Karschner. 1978.
