How much are old glass electric insulators worth?

On average, these glass insulators tend to sell for around $20, though there are special instances where insulators can sell for significantly more than that. Generally, the insulators that sell for more are rare, either because of their manufacturer or their color.

Are electrical insulators worth anything?

Color – The color of the insulator typically makes the most difference in value. For example, an aqua colored insulator might be worth $5, but a cobalt blue insulator might be worth $300!

What glass insulators are worth the most?

How do you determine the age of glass insulators?

The first number (MM) is the mold number, and the second number (YY) is the year (plus 1900) when the mold was made. Thus, “23-42” is mold 23, which was made in 1942.

What is the rarest insulator?

The rarest insulator I own is a Fry Glass insulator. It’s the same kind of opal glass they used on their tableware, called oven glass, because it did very well with heat changes.

How much are glass insulators worth?

What can you do with old glass insulators?

Old glass insulators are a popular item for numerous craft projects, upcycling projects, decoration projects and the fact that they are very cheap and relatively easy to find makes them a great material for DIY projects – lamps, succulent planters, garden lamps, table decorations, etc.

What is a vintage insulator?

Vintage Glass insulators were first produced in the 1850s for telegraph lines, then for telephone and power transmission lines. They insulated and protected the wooden poles from the electricity coursing through the wires. They are made from glass, porcelain, or composite polymer materials (non-conductive materials).

Do they still use glass insulators?

During the 1960s, 1970s and 1980s many of these lines were dismantled as technology advanced. Today, a few lines using glass insulators are still in service, but are only a tiny percentage compared to the heyday of open wire communication.

Are Purple insulators rare?

Collectors rate them according to age and rarity of color. Clear, aqua and green glass are the most common. “The rarest are glass insulators in purple, light green, deep amber and those that are threadless,” says Judy Tackett of Attic Delights in Orange, who collects insulators.

How do you date an old insulator?

Look at the insulator and try to find a date.

If your insulator:

  1. Has drip points, it was made during or after 1909.
  2. Is light aqua or green, it was made in Brooklyn, no later than 1908.
  3. Is dark aqua or green, it was made in Old Bridge from 1906 to 1921.
  4. Is light blue, it was made from 1915 to 1921.

How do you clean vintage glass insulators?

Use white vinegar to remove water residue and accumulation from years of the insulator weathering on the pole or lying in a field. Pour white vinegar in a deep bowl, and let the insulator soak overnight. Brush its teeth and threads the next morning. Rinse with clear water to remove the vinegar.

How old are ceramic insulators?

Porcelain insulators had their start when local potteries began making telegraph insulators in the 1850’s and 1860’s. These crude early pieces were usually threadless and were produced in much lower quantities than their glass counterparts, and few have survived the years.

What did glass insulators do?

A: Insulators are those glass or porcelain things you see on the tops and crossarms of telephone poles. Their purpose is to insulate the electrical wires they carry, so that electricity (or telephone calls) don’t all leak into the pole and into the earth. … Insulators were invented to fulfill this need.

What is a Hemingray 42?

The Hemingray 42, a telegraph pin insulator produced by the Hemingray Glass Company, is widely found in North America. Formerly. Gray & Hemingray. Gray, Hemingray & Bros.

What is a pony insulator?

“Pony” insulators, often no more than 3 1/2 inches in height, were used for lower voltage lines, while “Power” insulators for high-voltage purposes were much larger, sometimes weighing more than 30 pounds. The most common style is the “Signal” variety, used for communication and secondary power lines.
