                         Glass insulators were first created in the 1850's for use with telegraph lines. PS The cobalt Hemingray-19 was the most typical of the fancy blues, and made use of to sell for $30 or so, until an unscrupulous and greedy dealer traveled the midwest buying just about every 1 he could, cornering the industry.

 Pioneer Phone Organization in Kingfisher, Oklahoma has a small museum and is in search of red insulators. One particular of the interesting issues about insulators is that they parallel the improvement of electrical energy. The term insulator is also applied more specifically to refer to insulating supports employed to attach electric energy distribution or transmission lines to utility poles and transmission towers.
 Quite a few earlier insulators have bubbles, streaking, snow”, surface creases and other marks of crudeness which was frequent for this form of glass since top quality standards were not normally set as high as tableware. Mainly because of the iron content material in the glass, most of the insulators came out a tiny green, that is the common aqua colour you see and it's extremely frequent.

For new construction they will only occasionally use glass on the higher energy pylons. Glass Insulators are for use on transmission line and shall be of the typical profile cap and pin form.
 A: Insulators are these glass or porcelain points you see on the tops and crossarms of telephone poles. If they had an order for a whole bunch of Cobalt blue candle holders and they had glass left over, they weren't going to waste it so they would put it towards yet another glass item, occasionally insulators.
