Side B , By 1900, Hemingray had develop into a world leader of glass insulator manufacturing. Incorporated 1870 in Covington, Kentucky company produced glass bottles, jars, oil lamps, light globes, tableware and insulators. Right after discovery of natural gas in east-central Indiana, Hemingray Glass Co. located factory right here, 1888, and contributed to considerable industrial development of Muncie and state. No matter whether you are a collector or hunting for details on glass insulators, we are positive that with the details dished, you now know how worthwhile glass insulators can be.

• That’s what tends to make collecting insulators so interesting… all these rare experiments are out there.
• If however, an insulator is in good situation, it will fetch a larger cost at auction.
• I reside and grew up on the NYC man “airline” and a lot of the insulators are soooo varietied.
• The glass insulator is 1 of a lot of man inventions.

The massive insulator with the word “OHIO” embossed on it is a CD 302. Search google with additional info on the “CD 302” energy line style insulator made by Hemingray. I reside and grew up on the NYC man “airline” and a lot of the insulators are soooo varietied. The one I initial ask of is my Hemingray-42 but the quantity two is flipped over.. What are these four clear insulator owens Illinois cluster sets time frames?

My father gave me a Micky Mouse insulator in a milk electric blue. Most came in electric blue, but mine has so considerably milk glass in it, it’s practically opaque, and I consider it is a single of the only ones out there. Later on the suppliers decided clear insulators were more sensible due to the fact they attracted fewer bugs and heated up significantly less. There have been a few exceptions later on, when porcelain started taking over for insulators and they attempted to duplicate the colors.

The most well known color amongst collectors is Colbalt blue. That’s one particular of the colors Hemingray provided for their insulators, there are thousands of them out there. But they are so well known they are all snapped up right away, everyone desires them. To make insulators they made use of a lot of cullet, or recycled glass, and each batch of glass has some kind of cullet in it because it was a lot additional workable.

If it has round drip points, it most likely dates sometime involving 1924 and 1930. These dates are not “written in stone” but are as close to correct as collectors can be at this time. None of the aqua 42s have any variety of production date codes on them. Just after about 1933, the 42s had been mostly being produced in clear or off-clear glass, and by that time, date codes were coming into use. I am guessing you are speaking about a smaller clear “spool” insulator produced by Owens-Illinois, it is classed as a “CD 1049” and was created in the 1950s or possibly into the early 1960s.



Although the practice of collecting antique glass insulators only dates back roughly fifty years, it is a very well-known pastime, specifically in the United States. My father-in-law passed away not too long ago and he was a collector of glass and ceramic insulators. In all probability had close to 100 of them in excellent situation with many styles and colors which includes glass and porcelain insulators.

Are Clear Glass Insulators Worth Anything?

Threadless insulators made amongst the early 1850s to 1860s expense extra than insulators with thread and later models. Sadly, there are just about a couple of of them left. He initially designed them to safeguard homes against lightning strikes, but that changed when Samuel Morse invented the telegraph in 1837.

They usually bear a “shop letter” above or below the embossing on the front or rear, and/or with a letter on the dome. The shop letters recognized are A, B, C, D, E, “upside down L” , G, H, I, J, K, L , M, and backward N. There appear to have been at least 3 or four slightly distinct molds manufactured for every single letter except the upside down L. They are pretty popular with collectors because of the wide colour variety and the shop letters. The “HEMINGRAY – 42” style of insulator was the most common type produced by Hemingray, produced over a period of at least 40 years. Most of the earlier examples were produced in aqua , “Hemingray Blue” which is a bluer shade of aqua and shades of off-clear .
