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: ua-cam.com/video/yAhmBnVOFNE/v-deo.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!
Your voice is so soothing. I've been having a lot of difficulties with my mental health lately, which makes it harder for me to sleep, and this video is helping (that's not me saying it's boring, because I do find the topic of gems fascinating, but because your voice is so relaxing, it's helping me calm down). Thank you.
My first thought on hearing about the glass sponges: I DESPERATELY WANT ONE OF THESE IN MY HOME! My second thought: ...and it is all the people thinking like me who make such wonders endangered or extinct in nature. I'M A MONSTER.
@@SephirothRyu I hadn't heard about that, but there is a guy on YT who rescued a lobster from the "selection" tank. The lobster seemed to be pretty chill. 🦞
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.
Man, Michael--your delivery is so good in this. This isn't normally a topic I would be terribly interested in, but the way you spoke about it really let me follow along and absorb the knowledge. You were giving me shades of Levar Burton and other classic knowledge-presenters...of course with your own Michael Aranda flavor, too...it was really good.
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.
Has anyone else noticed that Michael never stumbles over his words? Like, ever. I don't know how he manages this. I would never be able to read a script so perfectly. 👍
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!
Thanks for sharing your knowledge of these little know natural phenomena.. they are indeed reflective of the ease with which nature creates it's wonders. your enthusiastic presentation was fun and engaging.
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.
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.
*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.*
(I posted content!) OPAL: 138nm to 241nm is the silica particle size range for precious opal AND it only forms that diffraction grating if there was an electrical field on the amorphous gel forcing the silica to ionize as it settled. My opalized snake head, along with the precious bones, teeth & wood casts from the Virgin Valley mining district in Nevada, USA, proves opal fossils also come from America. Check out the fee digs where people actually do find HONKING BIG BRIGHT black precious opals on vacation at the recreational mines.
@@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
The killer fulgarites I have to sell were made in a fine dust down in AZ. And the Vulcanite i dont have to sell came off the needle on top of Mt Thielsen in Oregon.
You can find opalized shells in Southern California off the 241 freeway near the landfill. I’ve found and still have them so Australia isn’t the only place.
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.
I hope it is someday possible to farm those cool glass sponges. Maybe it was through generations of cultivation get it so that they grow to at least a foot or two in less than 5 years. Or honestly I would settle for a reliable way of it's showing which ones are dead so that the dead ones could be collected from the seafloor. All very highly regulated of course but it would still be freaking cool to have one
@@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. ;)
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.
Geography fail! In the section on moldavite, the star on the map is over Moldova. It should actually be over the Moldau River in the Czech Republic.
I noticed. Thank you for correcting it.

you're not a monster, the fact that you thought twice about it shows you care about endangered species
Only if you actually do it.
I like that they are basically able to "domesticate" crabs.

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.

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.
Did you hear about the guy who put root beer in a square glass?
He made beer.

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.
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!
5:37 The moldavite inset doesn’t point to the Czech Republic; it points to somewhere between Odessa and Moldova.
This is fascinating stuff! We really need a Crash Course: Geology to bring all these Earth Science topics and systems together!
When you said living glass I immediately thought of diatoms.
Apparently they're crystalline
@@jasper3706 If you watched Into The Microverse's episode on diatoms Hank Green referred to them as basically living glass.
And me of X-men

I'm a flintnapper. Thank you so so much for finally talking about opal! I have been waiting for this video since the opal found me. Yep it found me.
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.

The burning hairs of nettles (Brennnessel in german) are also made silica. Also grass stores tiny glass particles in its structure (phytolites).
Obsidian is actually a fusion between a diamond a pearl a garnet and amethyst
