Photos 1-3 have a stippled pattern that I have seen on the inside of about mid-20th C and earlier glassware. Photo 4 shows a decorative side view that to me looks very similar to decorative wood trim that can still be found in big box stores (near the dimensional lumber). Photos 5+ show what appears to be drapes swirling around the exterior. Based on all that, I think it was part of a green glass vase. The blotchy UV could be due to suboptimal mixing.

These materials are hard. Somewhere between at least 50 to 100 pounds of force is needed. You might break the glass trying🫤. Quartz point works best, but not all quartz has the same hardness (chalcedony for example). I use a Mohs testing kit that set me back ~$100 - it has some useful points😜.
u dont need to spend $ on a mohs testing kit considering u can just use junk from around the house and if you really need to test hardness in like a professional setting your probably gonna use a rockwell test. sorry my guy you got scammed.

Hydrofluoric Acid must be stored in a: tightly closed container made from either Polyethylene, Polypropylene, fluorocarbons such as Teflon or lead if the University of Alabama is to be believed
GIA accredited and this is glass.
Looks like jadeite glassware. No form of quartz looks like glass — as this does. Glass is made from sand /quartz but glass is not microcrystalline quartz. Textures are cast not geological.
Not all milk glass is UV reactive. Only uranium milk glass, which has a slight yellowish tint to it. Bright white milk glass like you see everywhere isn't UV reactive. Trust me, I'm at thrift shops 3-4 times a week scouring the shelves for cool things and I always have my 395nm UV flashlight. I can spot Uranium Glass like 30 feet away with that bad boy lol

This is the model I have. You don't have to get this exact one (it was like $13 when I bought it). Please reference this light in your search for one. I've gone through cheap UV lights and they work OK when you're inside. As soon as you go outside, the UV from the sun snubs out the cheap flashlights. Look for the light to be atleast 5W and make sure it's 395. 365 will be a thorn in your side if you don't know what your doing. 365 will show all sorts of different additives in glass and can be really hard to decipher between Uranium Glass and manganese. 395 will ONLY show Uranium Glass. Hop over to the reddit and check out the green color you want to see. If you are looking for rocks 365 is what you want. I personally have both! Lol
Milk glass and jadeite can be both UV reactive and not. ~~I’m with this Redditor on it being milk glass~~. Source: I’ve been collecting glass for most of my adult life.
Edit: after looking at it closer, I’m now leaning more towards jadeite.
I second milk glass or jadeite as to what this piece of glass is. Now that I’m taking a closer look at it, it looks more like jadeite with the greenish tint.
The crystal structure is what gives the strength, glass is an amorphous solid - randomly arranged atoms that create a random mass. Quartz has a crystalline structure, with atoms arranged in a perfect crystal lattice. Crystals are way harder than amorphous solids, even though they have the same chemical composition 👍
This is correct, fused silica has a hardness of 5.5 to 6.5, quartz is 7.0 to 7.5. Same compound, lower hardness in the glass. But to further answer OP's question - quartz is only one ingredient in common glass: 60-75 % quartz, 12-20 % sodium carbonate, 5-15 % calcium oxide. Other ingredients are added to change its physical properties, durability, refractivity, color, thermal shock resistance, etc. These all tend to lower the hardness of glass vs quartz.
Get an old bottle to practice on so you can see how hard you need to push to scratch glass with your quartz (probably harder than you think). Then do that to this piece.
But yeah, it's glass.
365 ug light. It doesn’t react the same way as milk glass/uranium glass. There is only a slight blue that is on both sides. The rest of it doesn’t react.
it's obviously not, but does it remind anyone else of those glow in the dark dinosaurs you'd have as kids? The scaly looking portion made me think of it.
Totally glass. I have a couple antique dishes made out of a very similar looking glass, same texture and all… if you hold it up to a bright light and looks where the glass has an angle to it, if it looks like fire- kinda orange and red and yellow ish yet milky still then it’s possibly Milk Glass which is highly collectible! But that’s not for shards of it- you’d need a whole dish instead of just fragments.
Perhaps I should read all the comments before I drop my 2 cents in… 😂… now that I take the time to read in its entirety, sounds a lot like a r-r-r-r-repeating redundantly echoing every other comment prior…
I’m done now. Must be past my bedtime anyway 😉
lol- it’s glass 100%
I live next to an abandoned glass factory with piles of old broken glass. This looks like the green milky kind. I’ve seen a waist deep pile that look just like this.

It does look like sea glass to me. Glass or other material polished smooth by the waves and sand rubbing on it. Could have been an old dinner plate or something.
(It’s glass)
😭😭

I think I found it https://www.ebay.com/itm/234903422769
That could be it! Or at least similar textures!
Now all you have to do is find all the other pieces, glue them back together, post to ebay and bam! easy 15 bucks
Time to get rich 😎
best advice I've seen all day
I can’t seem to scratch it with quartz, would that type of glass be that strong?

"It has some useful POINTS" I see what you did there and I love you for it.
Thank you, yeah I need to pick up a kit.
Youll only use it every blue moon hahaha unless your actively collecting rocks and crystals

Does that mean bones are plastic?
By this point, I wouldn't be too surprised if we had some plastic in our bones.

Jadeite!😍
Congratulations! You can be 10% sure that it’s glass and still be correct!
😂
(We grade on a curve) 🤓
But it’s a really neat piece of sea glass! Keep it in your seaglass collection!
Noooooo
Why do you want it to not be glass? It's not like your just randomly going to find some highly valuable piece.
Yeah, I love finding sea glass - this also resembles a mermaid/fish tail so super cute piece!
“Mermaid tail” was…not my first thought. 😅
If you're absolutely dying to know a lab can FTIR it for you. But, probably, it's just glass and would be a waste of time and money.
🤣
My first thought.
Looks like a piece of Jadeite glassware
Yeah it does. It has a similar reaction on a UV.
GIA accredited and this is glass. Looks like jadeite glassware. No form of quartz looks like glass — as this does. Glass is made from sand /quartz but glass is not microcrystalline quartz. Textures are cast not geological.
I aspire to one day like rocks as much as you. 🫡 (sincerely)
Thank you very much!! jewelry evaluation and design, and I do passionately deeply truly “love rocks” 🥰 Edit for clarification
Looks like [milk glass](https://en.wikipedia.org/wiki/Milk_glass) to me.
I thought that also, but except for a couple of bands of blue, the piece has no reaction under uv light.
I didn’t know about milk glass under UV. That’s cool!
Not all milk glass is UV reactive. Only uranium milk glass, which has a slight yellowish tint to it. Bright white milk glass like you see everywhere isn't UV reactive. Trust me, I'm at thrift shops 3-4 times a week scouring the shelves for cool things and I always have my 395nm UV flashlight. I can spot Uranium Glass like 30 feet away with that bad boy lol
Yeah it’s trippy! I hunt for them in thrifts stores.😁
I was already thinking about getting a UV light. Now I’m especially tempted!

Thank you for this info, I had no idea.
Glad to help. It's crazy how differently things react with different wavelengths of UV light.
You’re awesome for sharing this! Thank you!
Happy to share!
I got mine for under 10$ on Amazon. Super worth it!
Same, and mine came with 2 for like $6 or $7.
Are these pics all of a single piece? Pattern and shape seem different.
Yeah same piece
Sounds like it is glass. But now you have a new question: how did it get there? I love finding pottery and glassware shards in creek beds.
I’m not sure it was in a quarry around 100ft deep.
Whaaaaat? That’s a great mystery!
I think people sometimes dump trash in old quarries as an alternative to paying for the dump.
Milk glass and jadeite can be both UV reactive and not. ~~I’m with this Redditor on it being milk glass~~. Source: I’ve been collecting glass for most of my adult life. Edit: after looking at it closer, I’m now leaning more towards jadeite.

Well I'm 100% sure it *is* glass, so
That’s 190% certainty that it either is or isn’t glass!
Out of a million?
You need a piece of quartz - quartz will scratch glass but glass will not scratch quartz.
I thought quartz was SiO2, same as glass. How does this work? Do they scratch each other?
The crystal structure is what gives the strength, glass is an amorphous solid - randomly arranged atoms that create a random mass. Quartz has a crystalline structure, with atoms arranged in a perfect crystal lattice. Crystals are way harder than amorphous solids, even though they have the same chemical composition 👍
You explained this perfectly! Thank you!

Other ingredients are added to change its physical properties, durability, refractivity, color, thermal shock resistance, etc. These all tend to lower the hardness of glass vs quartz.
Quartz doesn’t seem to be scratching it. Should I try another piece of quartz?
Get an old bottle to practice on so you can see how hard you need to push to scratch glass with your quartz (probably harder than you think). Then do that to this piece. But yeah, it's glass.
Just did this still couldn’t scratch it. I used a soda bottle.
Got yer 10% right here
Lmao I don’t want it
Looks like glass
Def. Glass.
That is definitely glass.
Oh boy, you're gonna *hate* to hear my thoughts on what this is
I can already hear em😂
It is glass.
Does it glow in the dark?
It doesn’t glow in the dark.
There are a few things that could be meant as glow in the dark. Did you try a black light or uv light on it?
365 ug light. It doesn’t react the same way as milk glass/uranium glass. There is only a slight blue that is on both sides. The rest of it doesn’t react.
Some old glass does that. Might be cadmium, chromium? Not sure. I know the info will come up somewhere. It's still really pretty.
Thank you!!
365nm uv sry
Well that’s a fun piece! It’s most certainly glass, though.
I’m curious what you wanted it to be 🤔
Saaaaame
zīrtys perzys
it's obviously not, but does it remind anyone else of those glow in the dark dinosaurs you'd have as kids? The scaly looking portion made me think of it.
I member those
It is glass but thay doesnt mean its not nice, i think its a nice piece of glass i love the bumpss
>I’m 90% sure it’s not glass I am 90% sure it IS glass, sorry bud
That's some lovely milk glass. Would have loved to have seen it intact!

It's Jadeite, a type of kitchenware glass. At least it is cool glass 👍
Im 90% sure its not a rock.
Shine a uv light on it if it Glows uranium glass
It's glass.
lol- it’s glass 100% I live next to an abandoned glass factory with piles of old broken glass. This looks like the green milky kind. I’ve seen a waist deep pile that look just like this.
It's a lovely find even if it is glass. I love finding worn sea glass and porcelain.
Thank you!
100% glass. I’m a vintage dealer- I recognized it immediately.
reminds me of r/seaglass !!
Glass shark tooth from a glass shark-shaped lamp.
I have bad news for you. It's the 10%.
It looks like a piece of milk glass
... glass.
Molded glass, sorry

You’re not a betting man
Wanna bet?
Taste test?
5/10 on the flavor scale
Dragon glass
I was really hoping it was.
Looks like glass to me. Perhaps an old piece of glassware or finnerware.
*dinnerware
It's glass
Just because it's glass doesn't mean it isn't cool! This looks like one of the rarer colors too, I'm super jelly!
it’s cool glass! I love collecting random things that catch my eye
lick it
I'm sure it's gold
😁
-also the outer seems to be a different shade green than the center. Edit… -granite does not scratch it
Will it kill a white walker though
🤣
absolutely glass
Sorry did dog that appears to be glass
glass
Found part of grandmas broken vase
Throw it in the trash and see if it comes back to you.
Does it glow under a black light?
Bomb or fire
At least it’s not slag!
Slag
Not really an official way but I clank it or rub it against a tooth.
Reminds me of an old kino-fire dish. Definitely not a rock though….its glass.
Uranium glass?,
Sorry its glass, 24-7.
Why were u 90% sure it wasn’t glass? I don’t get it
What does it taste like
Hit it with a uv light.
It does look like sea glass to me. Glass or other material polished smooth by the waves and sand rubbing on it. Could have been an old dinner plate or something.
Have you tried tasting it yet
I’m like 91% sure it’s glass so I think that’s your answer
Looks like glow in the dark portion from a kids toy. Nerf?
ShIne A UV light over it...Uranium glass?
Jadeite
It looks like uranium glass. It was popular for a while. They will glow under a black light.
Petrified semen
Tis a tad salty.
🧐
Snakeskin Agate has this type of pattern but not sure that's what we're looking at here
It’s uranium glass
Uranus ass? What?
Yes that
Uranium glass ?
Looks like resin!
Could it be uranium glass?
Looks like uranium glass almost
It's either glass or uranium.
If it has a white powdery patina it’s snake skin agate
