The manufacture of glass insulators began in the mid 1800s to meet the requires of the technology of the time. The objective of glass insulators was to insulate the electricity and telegraph wires from the wooden poles. With the development of technology glass insulators were made use of for telephone wires and electrical wires as well. https://umek.pro/products/iec-standard/open-profile The period 1920 to 1950 is the peak in the production of glass insulators, millions per year were manufactured, and nowadays most of the insulators are from that period. At about that time electrical businesses began to use porcelain insulators and by the 1970s glass insulators were no longer in use.
- Due to the fact then, hundreds of unique shapes and sizes of insulators have been developed to suit varying functions.
- Some appear like inverted thimbles, other individuals like mushrooms, nonetheless other people have odd-hunting projections that served to hold wires. https://umek.pro/products/iec-standard/fog-type-profile
- Katonak very first stumbled upon a bunch of insulators at a flea market in Colorado Springs in 1983.
- The Brookfield enterprise was among the top producers of glass insulators, with most of them coming in a blue-aqua color.
- The cone-shaped insulators had been deliberately made to stop dirt and dust from gathering on their surface.
This is on the base of a smaller green glass jar, possibly for an ointment. You have a whiskey bottle or decanter produced by Owens-Illinois Glass Organization. Please see my web page on that corporation, and scroll down to the COMMENTS section see the reply by “Carol” exactly where information on whiskey bottle codes liquor permit markings is pointed out. (Any related bottle with a “D-code” such as “D-9” or “D-126” can automatically be assumed to have held whiskey or some distilled liquor). Can you tell us something about the wood employed inside the insulators.

Mold quantity “33” on the base of an emerald green soda bottle produced by Owens-Illinois, Inc. Millions of these sorts of “generic” non-returnable soda bottles have been made for a lot of years. https://umek.pro/company/production This specific bottle was made by Owens-Illinois in 1984, as indicated by markings along the lower heel of the bottle . William Franzen & Sons- W F & S MIL marking on base of amber beer bottle. Most insulators are generally discovered in a really dirty situation, usually coated with a layer of gray or black “train soot”, or dirt and grime accumulated over several, several years of service in the outside environment.
Then telephones took over and got well-known, and there was the Rural Electrification Act, which attempted to offer power to all these farm individuals. So there was a major insulator boom in the early element of the century, they had been generating them by the millions. The most common color amongst collectors is Colbalt blue.
Whitall Tatum No 1 Antique Glass Insulator P1l
This silicone is the longest unchanged formulation in the business currently, is field established and laboratory tested, and remains the backbone of the MPS insulator solution line. This smaller glass insulator comes with two lines of threading. This allows you to use it in far more than one way, producing it a much more sensible and valuable insulator than most. The peacock blue glasses are the most sought-soon after among collectors.
