EIN (Embossing Index Number) 010 from McDougalds Price Guide, [At least best I can determine].
DESCRIPTION - Denver toll glass insulator w/ pretty good dome glass. Scattered small bubbles in the dome and a few larger here and there. A light color such as this is harder to come by than the regular Purple or Royal Purple colors. Displays mint. This one has been hit bu a small rock or a BB which caused a ping/chip and a fracture about 1" long from the base. Would look great in your window!

Now for a little background on insulators.........
Insulator History In Brief
Insulators have been used since the very beginnings of man's harnessing of electrical energy. The purpose of an insulator is to prevent the electrical current from 'leaking' away from the wire in which it is supposed to stay. The wire, being a conductor made of copper, aluminum or even steel, allows for easy travel of electricity, for that is what is desired to happen. But since it electricity will always go to the point of least resistance, we do NOT want it going down the pole and into the ground.
The earliest insulators were called Ramshorns because they had an iron head to hold the wire, and it was shaped like the horns on a Ram, a wild bighorn sheep. Overlapping in the time of usage with them were the threadless glass and porcelain insulators. They are what is often thought of when you talk about old and valuable insulators. Interestingly, threadless porcelain are much rarer than their glass counterparts. Yet they are not valued much more, and in fact are sometimes less expensive than glass.
In 1865, Louis Cauvet patented the bright idea of threaded insulators. This was an obvious idea in hindsight, but it made a huge difference in insulator usage in America, and much of the world, from that moment on.
Various substances have been used as insulators, the most common being porcelain and glass. As far as I know, there are no longer any glass insulators manufactured in the US, the last ones were generally thought to have been Kerr in the mid to late1970's. Other materials have been plastic, composition, and rubber, both hard and soft.
These insulators could have been used on old telegraph lines, transmitting Morse Code messages; carrying current along railroads [railway in England & Canada] to operate the signals along the track; they could have been used by a telephone company to give phone or telephony service out in the rural areas of the US. Some of them could even be used for carrying power [high tension] lines across the country. Mostly these are porcelain now, with some older ones of glass here and there.
Nowadays, there are very few of the smaller insulators still up and about on poles. They have been replaced by underground copper cables, microwave repeaters, and the newest method, fiber optic cable. [Which ironically, is also glass, but nearly perfectly clear and with none of the impurities that make the older insulators so pretty and desirable].
Sometimes people call them other names, like transformers, pole caps, pole covers or even arrestors; or use funny spellings like insoluter , insurlater, insultors, insurlaters, inshulators or my favorite incellator. No matter how you spell it or what you call them, these "Crown Jewels" are fun to collect.
Here are some terms used in insulator collecting, and that you might see in my descriptions.
SB = Smooth Base
SDP = Sharp Drip Points
RDP = Round Drip Points
CB = Corrugated Base
CREB = CRown Embossed Brookfield.
* I wrap EXTREMELY well by using; 1) A layer of bubblewrap, 2)Several layers of newspapers, 3) securely taped, 4) placed with LOTS of packing [not eating] peanuts, 5) in a BRAND NEW USPS Priority Mail box that is itself securely taped shut. All boxes are tracked by either delivery confirmation or insurance.
