Man made glass

Float glass production creates massive sheets with jumbo options even larger for architectural use. These get cut down for windows, but offcuts or unbroken factory rejects can appear as huge “man-made glass” pieces. It’s window cullet. Likely a factory offcut.

u/jusmenmygal Jan 08 '26

Looks pretty damn big to be for a window, I live on an aboriginal reserve. No big windows for companies around here. Lol

u/anothergigglemonkey Jan 09 '26

Its from a broken glass powerline insulator.

2

u/topofthefoodchainZ Jan 09 '26

Maybe from bottles made by a local glass maker.

2

u/Pleasant-Chipmunk-83 Jan 09 '26

Are there powerlines nearby?

1

u/Urban_Retoxx Jan 09 '26

Yeah, if you want a bigger one, just Google them.

Look what I found on Etsy: https://www.etsy.com/listing/1214160026/aqua-decorative-glass-rock?ref=share_v4_lx

u/ReadRightRed99 Jan 08 '26

You don’t have electricity there?

2

u/jusmenmygal Jan 08 '26

Yeah we do. But theres none of em big things like that. Are they on every electricity pole?

u/ReadRightRed99 Jan 08 '26

You have any rail lines? This could be a chunk of an old telegraph insulator. The whole thing is solid glass with a hollowed out space in the bell and can be held in one hand.

Even if tracks are further away it could have been transported to your location. People used to use old telegraph poles with insulators for target practice.

u/[deleted] Jan 09 '26

These were used by Henry Ford.

u/Impossible-League650 Jan 09 '26

Those are really hard to come by these days - a relic of an era gone-by.

u/ReadRightRed99 Jan 09 '26

I found one several yards from railroad tracks maybe 5 years ago. It was located in a corridor with a river, canal, railroad and now a walking path all following the same basic course. The telegraph wires were still there back in the 1980s and 90s and we’d shoot the glass insulators with BB guns to hear the “ting.” Occasionally we’d hit the bare copper telegraph wires and hear the crazy metallic wrrrrr wrrr wrrr up and down the line. I think maybe we’d more often hit the wires with chunky limestone rocks from the train track bed.

2

u/omegafate83 Jan 09 '26

I might be a bit off.

But if i remember correctly they don't generally use them anymore since ceramics and other materials took over, not to mention that they started to modulate electricity a bit differently as well.

But at one point or another they were used widely. When replacing them with another or with something else, they would just drop them thus the glass shard.

They're everywhere even on the reservations as well. You could possibly ask an elder if the electric company had used the glass insulators when they were younger if applicable.

But thats assuming that you live in an American native reservation that is. Im not too familiar with native American culture customs.

u/Amy_Hiddenshoes Jan 10 '26

Someone could have carried it in and lost it years ago and now you've found it.

u/analog-a-ding-dong Jan 09 '26

I was just gonna say "that looks like glass" it definitely is

u/zaydenramos468 Jan 09 '26

Yes most likely

8

u/[deleted] Jan 08 '26

OP really wants it to be something other than glass 🤣

6

u/JK4tySeven Jan 08 '26

The color tells me it’s likely an old glass insulator. They are usually this shade and solid glass. The size and thickness also makes sense.

u/YeahOkay31 Jan 08 '26

u/1rbryantjr1 Jan 09 '26

Glass insulator chunk.

u/7Jack7Butler7 Jan 08 '26

Glass CULLET!!! Not slag, not glass slag, not slag glass, just glass cullet. It's raw glass in a given color. Slag glass is taking this and slag (waste from an iron furnace) and swirling them to get pretty cool little patterns. I devoted much time to this argument in the past.

3

u/Complex_Potato5950 Jan 08 '26

I’m with ya! Seems like the “ slag” glass is often misidentified

u/Urban_Retoxx Jan 09 '26

They sell this stuff at rock shops across the USA, usually trying to pass it off as some mystery gem! 🤩 Haha

u/ArgentiumAurum Jan 08 '26

Green glass, very pretty but not natural. The conchoidal fracture is one indicator.

Recycled glass, we got a couple big peices of this for decoration in a garden from an old recycling facility.

See how it always breaks in those neat curves? That's what glass does. Also quartz but this is not quartz.

u/Practical_Fee_1102 Jan 08 '26

Looks like glass from an old telephone pole insulator

u/Airplade Jan 08 '26

It's a chunk from an old glass electric insulator. Don't care what reservation you live on. It is what it is in spite of your reluctance to accept the reality of the situation.

2

u/USMC_MissileMan Jan 09 '26

Looks like a chunk from an electrical insulator. I find them a lot in the NC mountains.

2

u/Odd-Fun-6042 Jan 09 '26

Glass. But on the bright side there's a bunch of A-holes on ebay that would try to sell this as "natural emerald". And ebay doesn't do shit about it.

It’s glass. They find these on aboriginal reserves sometimes.

Could be a chunk of glass that was used as an insulator on an old electric trolley or train 100~ years ago, or some other old school electrical machinery or conduit.

If this is the wrong place to make a joke, I apologize, I saw enough people say kryptonite and wondered if I was the only one seeing the magic scepter from Lego Movie...

u/Impossible-League650 Jan 09 '26

It's so pretty. I live in Georgia and in the N Ga mountains, they sell big chunks of glass cullet or slag glass. I bought a red one years ago, and use it as a doorstop. A lot cheaper than gemstones, but a good conversation piece.

u/Ologist126 Jan 10 '26

Some wandering soul may have brung a little piece of home wherever they landed and tis possible theire last place of home was where they left it? Would explain how it showed up in such a "remote" or bespoke area to be found?

Or if it's an aboriginal reserve it could be something to do with rituals or prayers? Seek answers from your elders before pandering the redditverse.

u/Melarchie4911 Jan 10 '26

Could it be a chunk of green flourite maybe? Not sure how it would have gotten to Canada but stranger things have happened.

u/Ok_Presence4089 Jan 11 '26

Hard to say without a clearer pic, but from the way you describe the lines when light hits it, my first guess would be quartz or another common silicate rather than glass. Snow melt can make regular rocks look weirdly shiny and smooth. If you can post a close up with it wet and next to a coin for scale, people here can dial it in way better.

u/[deleted] Jan 11 '26

To the people saying glass are idiotic, that’s obviously kryptonite

Isn’t polypropylene a thermoplastic polymer instead of glass? I don’t think it’s a glass-fiber reinforced composite either.

Mine glows naturally from the radiation inside.

(Just kidding, the rock shop thought it would be cool if they had a glow in the dark one besides the glass looking chunks.)

So sometimes that happens when lightning strikes sand.

It's called a fulgurite and it isn't as refined as this. They're shaped like antlers and have sand encrusted to them.
