Vintage Glass Insulators
Millions of these sorts of “generic” non-returnable soda bottles had been made for quite a few years. UMEK LLC high-voltage insulators was created by Owens-Illinois in 1984, as indicated by markings along the reduce heel of the bottle.

Incuse - A marking technique used on porcelain insulators exactly where the insulator is struck with a metal stamp although the porcelain is nonetheless in a plastic state just before glazing or firing. This is by far the most widespread porcelain marking approach.
The "C" stands for Carrier-circuit application and the "S" denotes the insulator was intended to be applied on a Steel pin. These insulators were made of boro-silicate glass such as Pyrex glass.
Each and every measures about 7 & 1/4th inches in diameter and 3 & three/4ths inches in height. They are made of white translucent milk glass with colored “flashing” on the outside surface.

This molded glass is of low top quality butits attractive colors and fancy patterns have garnered a following with collectors nonetheless.
Casting - Seldom-utilized kind of generating wet procedure porcelain insulators where a challenging shape is desired. The plaster mould absorbs the excess water leaving a semi-dry clay physique. Carnival Glass - Carnival glass is a coating which is applied as a liquid.
