I wish you would stop "Powerpoint Slide"ing your videos. When you post the words you are saying as part of your video... and then say those words, its redundant. If I wanted to turn on Closed Captioning, I'd do that. Rendering the words and then reading those words is useless. I'm in meetings all day and when a person is saying the exact words that are on the screen as the words are on the screen is terrible. Stop the Powerpoint Slide Video style. PS: i like the content and the presenter, just not the delivery method.
The Virgin Valley Opal Mining District in Nevada has Black Precious Opal fossils too. Usually Twigs, like this one: th-cam.com/video/yAhmBnVOFNE/w-d-xo.html , to trees and rocks, but also animal bones and casts. I also have a Facebook Group for Swordfish Mining about the valley and its mines and gems. You can even pay some owners to mine their claims. (How about the little glass beads without any inclusions in the ice cores?)
The one thing this channel lacks is more visuals for the things they’re discussing. Sometimes what they’re talking about would be awesome to see, but all we get is text on the screen of exactly what they’re saying. I think adding more images or even video clips of what you’re talking about would take these videos to the next level!
Fun fact: One thing many people don't realize is that if you're wearing an opal ring, and you reach into a freezer, your opal can break, and sometimes even shatter. That's because of the water in them. Water expands when frozen. Opals are very fragile.
This is a great video! it reminds me of the time hurricane sandy hit my state, during the clean up some (idiot) guy tried to cut off a branch that was leaning on a live power line and ended up severing the line itself. when it hit the pavement it melted the asphalt and now I have small pieces of asphalt glass that was left over after it was safe to go near it.
Talking about glass, could you guys talk about trinitite (nuclear glass made after the trinity nuclear tests) minerals like chernobylite and the potential for nuclear waste containment by using glass/making more inert glasses? I've watched nearly all of sci-show's episodes and love your channel. Thank you for all you guys do to bring science to the masses!
frogster eighteeng does foam on freshwater lakes also contain diatoms? I have noticed that, on the small lake in NE PA where I live, different times of the year will have (slightly) different foam form when strong winds blow, but I never gave it enough thought to try to look anything up, but seeing your comment piques my curiosity, and different diatom growth at different times of the year could explain it.
I remember in my first year of college, my bio professor brought in one of those basket sponges to pass around. I was amazed; until then, I always thought of glass as something man-made. They're really cool!
This is one of the most concise and succinct descriptions of SiO2 natural glasses. Thank you, I really enjoyed this video. Some less common types of volcanic glass are of a mafic nature known as Sideromelane & Tachylite. If there are other glass nerds out there let me know if you know of other natural glasses out there.
*This morning I woke up wondering how mirrors are made, I watched several videos on YT, continued onto several videos of how glass is made... and now I sit down and see this!!! When reflecting back on the situation, I find the coincidence funny.*
The opal tech. is getting pretty advanced in lamp-working. You can't use natural opals the water content is to high they just blow up, but you can encase synthetic opals; greens, red, blue, white, RGB.
@@fahrinurlaub01vg Or for schizophrenics, and some others on psych meds. I've seen that a lot but there's no obvious pathology going on. Not that you could diagnose from a few minutes of a video. BTW, I probably blink more than you do. Females blink more than males, so I think I'm more common than I even realised. ;)
There is an error in this video! At 4:24 the video says "but Australia is also home to the only known specimens of opalized fossils", which is not the case. Opalized fossils can be found in Nevada in the form of opalized petrified wood.
Haha another reference to Blue Planet II. They seem to have found quite a few new things while filming like those venus flower baskets trapping (or sheltering) krill where they can happily live and breed away from predators.
One my uncle's used to let us play with his obsidian collection he gathered near the volcano in Mexico city. Taught me how Aztecs made weapons from this glass . Pretty cool stuff
@@JustAnotherAccount8 so you think. Common opal is found abundantly here and all along the west coast. Why can't opalized Shell be here, too? Do some research, do some science. You are laughable thinking you speak for all of science. Ha ha ha
I was gonna suggest Tektite formation sounds very similar to Fulgurites of course being mechanical in nature rather than mechanical, then the Fulgurites bit comes on :D
Actually early circuit boards did not use glass as they were FR2 type construction IE Compressed paper and resin with copper traces. Modern really high frequency PCBs are still ceramic and cheap ones are still FR2. And by high frequency I do mean these days 200GHz+. It was not that long ago they needed to be used for 1GHz hybrids.
That was fascinating. I saw a movie, I think it was Sweet home Alabama. The male lead made glass sculpture by standing star pickets into the sand just before a lightening storm. The steel stakes were hit by lightening and after cleaning etc sold as sculpture. Is this possible or is it just a movie stunt.
Glass is great, just sucks when it breaks ;p I have a shard of glass in my foot for over 10 years now and it can't be cut out. Its too tiny and they are not even sure where exactly it is. As much as i hate glass, i also love it hah
Thanks for the info! It's impossible to find good, well sourced pics and info on some of these, the good geology sources always get drowned out by sites with names like "healingcrystals.net"
Can fulgurite be synthesized? You would think we would have the ability to direct enough heat energy at wet sand fast enough to mimic the result of a lightning strike. 🤔
Which, if any, naturally occurring glass can end up looking close to a flat clear sheet of glass - that we may could then make windows in our house from? thanks

1: Obsidian (0:53)
2: Opal (2:13)
3: Tektites (4:33)
4: Fulgurite (6:23)

They left out "Trinitite" which is the green glass formed from the test of the first Atomic Bomb at Trinity Site, (north of Alamogordo), New Mexico.

opalized fossils are probably my favorite natural occuring objects!
Mine, too! They combine to of my major interests! Plus, they're just darned beautiful!
I've always loved opals. I'm glad they reached this list.
So Minecraft lied to us. You have to remove water from lava to get obsidian.
it kind of didn't at the same time you need to cool lava fast to get a glassy structure
Also obsidian isn't really hard to break, it shatters pretty easily
However it does have the sharpest edge known to man.
@@jasper3706 I think their just being super careful so they don't shatter it. That is my reason for why it takes so long to break in Minecraft.

an 8 story high glass sponge? picture please
Yeah, so far, I only heard 1 story about them. Where are the other seven? And in which one does the sponge get high (and on what exactly) ?
@@DreadX10 haha
I would LOVE to see a pic also!
I love opals, never knew how they were created though. I learn something new with every video they upload, this is such a fascinating channel.
5:37 The moldavite inset doesn’t point to the Czech Republic; it points to somewhere between Odessa and Moldova.
I saw a meme with this guy that said "If the year 2005 was a person" and now I can't get it out of my head.
Celephaith he looks like every punk rock frontman ever lmao
i thought they'd mention diatoms (single cell alge with glass bodies instead of cell walls).
Are diatom cell walls amorphous silica (glass) or crystalline?
@@TJStellmach I just looked it up, they seem to be crystalline , so not technically glass link.springer.com/article/10.1007/BF03051518
@@austinfernando8406 Honestly having a crystal body is significantly cooler than having a glass body
Another thing cool about diatoms is that the silica is a major ingredient in sea foam.

Obsidian is actually a fusion between a diamond a pearl a garnet and amethyst

But so are Venus flower baskets I guess 😍
No it is not poopsie. Diamond, garnet and Amethyst are all minerals, pearls are byproducts of living processes and Obsidian is Glass.

The burning hairs of nettles (Brennnessel in german) are also made silica. Also grass stores tiny glass particles in its structure (phytolites).
