❤ good advice 👍 brother

What if it has bubbles on part of it but that part doesn't look like glass at all and the glassy part doesn't have bubbles? Are there other stones that look similar or is it slag?

Wow!!! Thank you for the information I have been looking

Thank you! This is so incredibly helpful! You can only get some much from 2D drawings in a textbook.

Everything checked out that what I found is slag....except light was shining through the thin edges.

I would love to see a video IDing the differences between slag and chalcedony.

I bet a lot of people see your japanese maple in the back and think its 420 😂

When rocks don't have legs, who put the slag glass in to these absolute nowhere places?

Raaaah! You mean it’s NOT a diamond! You just crushed all my hopes and ego! Jk. lol

I need help I am a rock hunter that has acquired a very good collection. My favorite is obsidian and others like it. That glassy look and smooth. I wish we can talk other than here so I may send pics. I am a beginner and I would like to send you pics of my collection. I have one peace that no one knows what it is. At least here in El Paso,tx. I found a gem I thought and was told it may be a diamond but it is not. Also it is so tiny but the luster and shine is one like a diamond. I was told it may be a nice quarts or diamond quartz.

This is RADDDD!!!!!!

It's unfortunate that there won't be any more episodes of Primal, but I really enjoyed the series while it lasted.

30 yeas ago I went fossil hunting on a beach near Parksville BC Canada and found, on the graveled sand surface in plain sight a charcoal black well worn and rounded 2 inch rock (likely from being buried in the shifting sea soaked beach sand for untold time) with a recent broken end of black shiny circular obsidian like fractures and light could shine through it with a clean dark golden greenish colour quite likely broken by a previous fossil hunter then discarded it before I encountered it . The area was a popular beach area with scenic hills, cliffs and forests and the black rock was at the back edge of the beach on top of the coarse sand. Recently It was confirmed to be obsidian by a local archeologist after showing it. I would think that rock is an ancient human sourced artifact possibly centuries even thousands of years ago . Im sure that beach area was as popular a place for ancient native peoples as it is for the present local public and tourists alike. Obsidian was a highly valued commodity among many ancient native tribes and is not sourced in my area, it likely was traded and traveled hundreds or thousands of miles by foot and canoe from the mainland to reach my area.

Fix subtitles in your video. Auto-generated is korean languqge.

I ruined my son’s day by making him watch this video 😂

Thank you for this! I did not question if I had obsidian. But I have "bog iron", hematite, limonite, pyrites with large black crystals in them once you split them open. pieces poke out the large balls. There are smaller pieces with smaller ones. The black glass has copper gold shimmer through a loupe- but also tiny circles. It is beautiful in the hematite and limonite. Found on Western shore of the Chesapeake bay I went back and got more they are so beautiful inside! And its so fun to split them and see whats in there!

I found some really black crystal in the side the beach. Looks like obsidian, but no Vulcan here in Massachusetts

I thought you’d like to know I originally found your video via Google, but I didn’t see a way to click Like or add a comment, so I went onto KZfaq, and searched for your video again. Good production quality, great choice of background music, amazingly great attitude! Favorite parts: savoring the moment inside the crater, the fact that I think I heard you call it a sink hole, and your closing suggestion to stop watching, get out there, etc. Brilliant! Keep up the good work!!

Excellent video. I learned a lot.

Excellent. this was helpful. I finally understand the shapes of crystals. Thank you so much.

The piece i found has a trait from both obsidian and slag and im confused The edges let light through but there is just one air bubble (its more oval) on one side of it

Awww. I knew it was more likely that I’d win the lottery than find obsidian in the UK but I found a few pieces of basalt too, and with the place I found it being a footpath made from excavated materials to make way for a housing development, I thought I might have got lucky. There’s bubbles, bits of dirt and even iron/steel “bearings” in it. I can still knapp it though so happy days.

that shit is worse than rabies on steroids 💀

7:25 Thanks, because of this we had to return the fake ones.

so what do you think of zincite, an industrial byproduct

Thanks for this, I've been scratching my head over some big-ass chunks I found lately (1000 miles from the nearest volcano, but 100 yards from the old foundry!)

This was very helpful in understanding the differences between crystal systems! thank you very much.

this was actually helpful, well mine can pass light at the edge so it must be obsidian.

I've read that what makes obsidian isn't the fast cooling but the lack of water in the flow. The evidence was the Big Obsidian Flow in the Newberry Caldera in central Oregon. The size of the flow is such that it would have taken some time for it to cool yet it is obsidian clear through. Obsidian is chemically the same as pumice without water that causes the frothing. You can find in the flow obsidian that has some frothing similar if not the same as scoria. Thanks for solving a mystery for me, I have some of the opaque green glass you showed that I got in an estate sale. I knew it wasn't obsidian but didn't know was it was

Maybe you could make a video about the difference between quartz vein and aplite

Great video, there aren't any good videos about aplite on KZfaq

Drugs are bad kids Mkay.

Slag glass CAN BE totally clear and let light pass through. I’m a glass artist and have use totally clear colored slag glass in my pieces. When I’m looking for slag glass for my pieces, I specifically look for beautiful CLEAR pieces. So don’t take transmission of light through a piece as defining whether you have found a piece of obsidian or slag.

Hope someone sees this what if it's varrying colors of green all the way from black that show green when put to light all the way to a yellowish green and everything in between the bigger pieces have no bubbles but all the smaller lighter pieces do only inside them not outside and there very smooth

I have green slag with black flakes in it when put over a light. I thought it was Williamsite but slag makes more sense. No one has been able to tell me why it has black flakes though.

Serendebite vs obsidian difference?

Tom Green vibes.

Well, I guess since we lived less than a mile from a gas and coke plant when I was a kid, the BEAUTIFUL BLACK VOLCANO ROCKS we would find on this big hill in our neighborhood were most likely poisonous slag glass. Niiice. 😮 Wonder how that mountain of slag got there right in the middle of an entire neighborhood of houses 😂.

Very often I used to find slag from antiquity and even older, over 2000 years old, and it is completely identical in 50% of cases to black obsidian. With this slag, some specimens are enriched with inclusions of peridot, which is full of sparkling dots, like yellow-green opal or zincite. This slag must have the same value as zincite crystals, which are actually the same slag in the zinc production process. These beautiful pieces must be officially valued and have a price like obsidian or even more.

english isnt my mother tongue, but you made me understand about the crystal systems, thank you so much !!

8 minutes in and this guy single handedly cheered my day up from dread and taught me what my proff couldn't in 2 hours. Ur the best

I have a piece that matches every description of green obsidian, except it has small visible bubbles on the inside. I read that sometimes bubbles visible to the naked eye can be trapped in lava flow, during crystallization. Mine is completely transparent and nearly translucent. I also read that the inclusions that cause the thin flowing bands, in green obsidian, can cause its green color. Moreover, in my research, I read that those trapped bubbles can cause its green color. Is there a way I can send you pictures or videos to examine? I'm completely devastated, as you said. It matches every description I've read, including lythiophysae.

HaHaHaA .. I already have a rainbow n a snowflake obsidian as a pendant .. rainbow obsidian was cut n drilled while snowflake obsidian was given as gift n made into a double terminated point 🤔 BUT their efficacy / effect differs since rainbow tend to be dark , blunt , glossy while snowflake Might be a bit differrent in texture due to its snowy flecks known as 'christobalites' formed alongside dark obsidian 🤔🤭🤔🤭🤔

Welcome back! Can’t wait to see the new content you talked about, but I know balancing that with school can be hard. Take your time, one of the things I like about your videos is the energy and how genuinely passionate you are, the last thing I want is for it to seem like a chore than something you enjoy doing.

Great info, but there are slags that do have some translucency. Leland Blue is a great example of that.

Thank you so much for this helpful information! I’m a little disappointed my mound of obsidian I thought I fumbled upon was in fact flag 😂 Oh well! I’m glad to know the truth!

I live in Ohio and kayak along the Ohio river for arrowheads and native artifacts. I’m just now getting into geology. I found a ton of slag glass that is black with tiny golden veins. Looks beautiful. Makes sense with all the steel making that happened in the region

Great to still see you Rockin and Rollin ! 🔴
