Glass Insulators 002

What the heck are they?

You’ve seen them. What are they? Well, back in the day, they were installed high upon the cross-arms of wooden utility poles. They’re insulators. As my public service, I’ll share a little bit about insulators, so that, if you put some in your place, you’ll be able to tell people what they are. And no, I wouldn’t bring up the subject at a cocktail party. Unless you see me there.

This pretty one has multiple skirts and a slotted head.

These glass (and porcelain) insulators were used by the telegraph, electric power, and telephone industries. They were made by the same companies who made art glass: beautiful objects of decoration, and useful objects such as pitchers, drinking glasses and tableware. They were contracted to produce glass insulators. Here are two examples of art glass: a family piece of EAPG, and a stock photo of hobnail glass (I had a piece, but stupidly sold it!).

My 1891 Beatty EAPG Pattern Glass Feather Fine Cut spooner from my mother’s family, is beginning to turn purple with age (chemical changes).

This vintage hobnail glass toothpick holder has features similar to the following insulator.

I’ve displayed this one on its side to show its hobnail-patterned base.

Due to conductivity and/or interference issues, you don’t want to just nail a wire to a wooden pole. You need something between the pole and the wire. That’s where these “crown jewels of the wire” came into play.

Many people, including me, collect them for their beauty. We also collect them simply because they’re interesting objects. I’ve never climbed a telephone pole to string wire; I’ve never gone “searching for an overload”, like the Witchita Lineman; but I think glass and porcelain insulators are really special.

Purple majesty.

Insulators can be found in many colors. But there is no color coding involved. Basically, the colors don’t mean anything. I think it’s great that they come in colors, for no reason at all. — Well, there is one reason: since glass houses made both glassware and insulators, they would use the leftover glass from their art glass-making process to produce insulators. Which does account for some insulators’ exotic colors.

Here’s a rather complex one.

They were made in many different styles, depending on what kind of wire they went with, and how the wire went around/through them. Many different companies made them. I don’t collect any certain company’s product. I’m not a nerd about it. I just like having pretty, unique things in my décor.

Porcelain insulators.

I don’t know much about the porcelain type of insulators. I only own a few. Most of the ones I see come in basic brown; and I’m looking for something different. (Last September, I passed up a chance to buy some beautiful off-white porcelain ones at a Puyallup, WA antique mall. I don’t live near Puyallup; I am still kicking myself.) I did manage to learn that porcelain insulators were introduced because the protective properties of porcelain proved superior to glass. But I don’t know what that means! I’m an art collector, not an electrical engineer. But glass ones, which were first made in the 1800’s, for telegraph poles, were eventually phased out — by the 1970’s  — making them rare. Porcelain insulators are still being made. For the beginning collector, porcelain can be more affordable.

Treasure house?

You may have seen some of these insulators in an old man’s garage. But take them out of the garage, dust them off, put them in an out-of-context spot in your abode, and you have an attractive conversation piece. I can’t show you a photo of one of my insulators against a minimalist, industrial-design background, because I collect hundreds if not thousands of vintage items. I’m not into minimalist, industrial design. But if you have that kind of décor, insulators would go nicely with it. — I believe the #1 way to employ them in a modern interior is to convert them into pendant lights. This is becoming quite common. Turn one into a pendant light, and its value can go way up (unless you do that to a very rare example — those should be left as-found).

Just a small part of my folksy/homespun/rustic décor, with insulators, which I use to camouflage my blah-partment.

Old blanket, old insulators.

These are displayed on my beacon blanket which I’ve had since 1952. You can see how I’m into the true vintage feel.

I wish the hues of this beautiful cream-colored one would come through in the photo…..

Where to find them: antique malls, flea markets, auctions, second-hand stores, garage sales. Isn’t that where you find anything cool?

Here is another cream-colored one; a really wild one.

I’m putting photos of as many of my good ones as I can squeeze in here….

The wires attached to this one make it unique. I’ve seen these used to hold photographs.

If I see a one I like, and I can afford it, I buy it. I’ll buy an imperfect one (cracked/chipped) if the price is right, and it’s pretty. As with all of my collections, I’ll rescue a damaged item, in order to give it a home. You can expect to pay $3-5 for simple, generic insulators (clear or aqua); the prices go up from there. The most I ever paid for one was $15. It was the purple beauty seen in the photo #6, above, that I found twenty years ago at a Seattle second-hand store known as J T’s Attic. It remains the only purple one I’ve seen in person. I’m so glad I bought it. (Oh, BTW, I want to stick this in here so that I don’t forget: prices will be higher in Portland, Oregon.)

Domed top.

How I got into collecting: I started collecting insulators in the late 1980’s. While “antiquing”, I would see them sitting on the shelves. For something so pretty, and interesting, they were always priced reasonably. I started picking them up. I slowly amassed a small collection. I’d say most of mine are from the 1920’s-1950’s. — One day when my wife and I went to a local auction, I noticed that a whole box of them had been placed in the auction. I took a good look at them at the auction preview, found them to be in great condition; and later that day, I picked them up for a song! The auctioneer, after hitting the gavel, said, “Nice buy!” Well, she didn’t usually make comments. So I will take her word for it. — I got a nice buy! That purchase really bulked-up my collection.

Modern times.

This modern-day utility pole is outfitted with modern-day insulators. The old glass ones are for collectors and repurposers, now. — It looks to me like they’re using a variation of the porcelain or ceramic ones here.

I can’t help but wonder how long telephone poles/wires will last? I can’t imagine anyone having a land line ten years from now. I recall visiting with a young friend back in 2002 or so. He told me he only had a cellphone. I thought how odd that was. Now, of course, I only have a cellphone. This has been the case for five years…. I’d love to see all of those poles and wires gone. I’m a photographer; I’ve had more photos ruined by wires.

Ruined by wires!

I looked it up; basically, we still have telephone poles for economic reasons. Electric companies use the wires to deliver electricity to our homes and businesses. It’s very expensive to bury the wires. — Although, that’s being done more often. I think the poles will eventually go. We’ll have to collect photos of telephone poles….

Ruined by wires AND pole! And the car doesn’t help….

Dug up in London.

Update: With a little help from my friends: 1) My friend Gray, who lives in London, and who produced my 1960’s band’s retrospective CD (The Velvet Illusions’ “Acid Head”) actually dug these up in London, about twenty years ago (see above). He recently shipped them to me, as a gift. They’re porcelain, and very different from anything else in my collection.

Space Age beauty.

2) My friend Clyde, who has a vast knowledge of vintage items, sent this Space Age beauty all the way from Tennessee, as a gift. I think its design is fabulous. With its double-ringed top, this mid-century insulator was mainly used on rural telephone lines. Per the Hemingray Info website, “This style was used for swapping the positions of two lines. This would reduce the interference that would otherwise be caused by two lines running parallel to each other for too long a distance.” — I haven’t been able to add many insulators to my collection lately. But thanks to kind, generous friends like Gray and Clyde, I’ve added these excellent examples, which I will treasure.

BTW, I haven’t listed all of the names and ID numbers of these insulators. I’m tryin’ to keep this fun, casual, non-nerdy. Yes, most of ’em have names and numbers on them. If that interests you, you can always leave a comment and ask me for that info.



There’s only one song which can accompany this story:

I took all of the photos for this story, except the one of the ruby glass toothpick holder. And, then, my camera broke!
