Occasionally an person mold can be identified by studying and comparing insulators that were developed from it more than a considerable stretch of time. Adjustments in the mold, such as re-cut (re-tooled) engraving, repair, or the addition or erasure (“blotting out”) of the engraving can be found upon quite close inspection of the insulator. Thus, the comparison I’ve produced to the coin collecting hobby, with the a lot of slight variations in coin die design and style details, as revealed under close scrutiny by really serious collectors.

They also have the numbers 7,8,10,11,12 and feature a dot at the top. The CD 141.9 Emminger’s glass insulator is an all-time classic collectors, even seasoned ones, drool at the word Emminger’s. In addition to the dome-shaped major, the insulator comes with a hollow top to the dome’s interior.

• There were plants all over the spot, transportation and fuel had been a big factor.
• History reveals that glass insulators came to life in the early 1850s via a man referred to as David Brooks. glass insulators for sale
• These Montreal Telegraph glass insulators are slightly taller than the regular insulator but have a milky hint if looked at meticulously.
• The Hemingray Glass Corporation made the DC 151 H.G.Co.
• I believe it is less costly to manufacturer and mechanically they are a little stronger.

Often, all your piece desires to sell is the name behind its production. Preferred manufacturers are directly proportional to well-liked demand due to the fact they’re commonly renowned for creating good quality things. When dating a glass insulator, make positive you count all the dots about the year code and add them to the date of the mold manufacture. Doing this will enable you figure out the precise production date.

So I asked him about them and it turns out all the original insulator collectors have been linesmen. They’d go out and do a job and there’d be an old pole with antique insulators on them. They’d swap out the old ones with the new ones and to everybody else, the old have been just junk. So my neighbor knew a lot of other insulator collectors and it just went from there.



As long as the insulator performed it’s duty adequately, the color and minor imperfections in the glass had been of tiny concern. These “marks of crudeness and age” now add to their value and charm to collectors of antique insulators. When the telephone providers would take down a pole, they wouldn’t save any of the insulators, they would just throw them in a hole in the ground. So there’s a lot of the old uncommon desirable stuff out there, been buried for years. Generally the guys who uncover the old ones do a lot of research on where poles made use of to be and they’ll spend lots of years digging around.

Glass Insulator Values

The most typically used glass insulator cost guide has been published for many years, in several editions, initial by John & Carol McDougald, and in additional current years by Don Briel. A quick search of the world wide web will bring up web-sites where those books can be purchased. As I’ve described elsewhere on this web site, my key purpose right here is to concentrate on the background and history of the glassware being discussed, not on values or costs. This website is not intended as an appraisal supply so little attention has been offered to values. Nevertheless, given that the subject of values does come up generally when people create to ask about insulators they’ve identified, I really feel that it is greatest to address the concern in this article.



Sometimes you’d even get swirls if they didn’t mix it properly. There’s a batch of incredibly good green insulators created by McLaughlin in Vernon, California. He got a truckload of green gin bottles and melted them down and produced a batch of insulators.
