What is the rarest glass 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. It was a popular kind of glass, but their insulators didn't sell well. via
Are old glass insulators worth any money?
Old glass insulators can range in value from $2 up to over $400. Like other antiques, glass insulators are evaluated on several criteria: Age. Rarity. via
What is the value of insulators?
Insulator price guides generally give a range of values (e.g. $20-30). The high end value is usually Mint (no damage), and the low end value would be Near Mint (some damage). More extensive damage would be valued even lower. via
What can I do with old glass insulators?
When did they stop using glass insulators?
As the telecommunications industry changed, the insulators began to be dismantled in the 1960s. via
How much is a Hemingray 42 insulator worth?
What Are Hemingray Insulators Worth? Because the Hemingray-42 insulator is one of the most common, they tend to be an affordable collectible. Most sell for under $10. via
How do you clean old 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. via
How do you drill holes in glass insulators?
Use diamond bits to drill your glass, not carbide bits. Use diamond hole saws to drill holes 1/4″ and larger or to drill holes in thick glass like glass block or wine bottles. Use plenty of lubrication/coolant to keep your drill tip cool and the hole clean. Use less pressure! via
How do you date Hemingray insulators?
This can be found on all Hemingrays right up until they stopped manufacturing insulators in 1967. In this version the mold number is to the left of the dash, and the date is the two digits on the right side of the dash opposite the mold number. via
What do the numbers on glass insulators mean?
All Hemingray insulators since 1933 have had mold and date codes on them. In the Price Guide, these are generally referred to as [Numbers and dots] and [Number]. The last digit (plus 1930) is the year the insulator mold was made. Thus O-4 means the mold was made in 1934, O-8 means 1938. via
How do you identify glass insulators?
The CD (Consolidated Design) numbers basically identify insulators by their shape and profile, regardless of exact embossed markings, glass color, or base type. via
What is a Hemingray insulator?
Hemingray was the world largest manufacture of glass insulators. The earliest Hemingray insulators are likely lightning rod insulators from the late 1850's. On style we know of is the CD 732.2 “Floyd Patent” (May 14, 1867 - Patent No, 64,654) it had a pin that snaps in o a groove at the very top of the insulator. via
How do porcelain insulators work?
Power lines and other electrified wires transmit high-voltage electrical energy along suspended wires. While the wires themselves typically contain no insulation, certain spots along the electrified wires require insulation. via
How do you make a hanging light of electric glass insulators? (video)
What is a ceramic insulator?
Ceramic Insulators Ceramic insulators are ceramic materials used to insulate electrically-conductive materials or temperature-controlled enclosures. In the context of electrical insulation, ceramic insulators are usually limited to the insulation of electrically conductive materials on an industrial or municipal scale. via
