I LOVE ❤ this channel! Super excited that I correctly identified botryoidal and dendritic properties. However, the last specimen looked like a petrified pickle.😂
The round one was maybe an old clear glass marble, a common find in creeks/washes. It would explain the millions of bubbles he saw before he polished it as well. Also might explain the fracture in it.
I have an interesting rock that I found in the desert of Saudi Arabia. It's round, with a concave depression on the bottom, and it's vitrified, with a fairly smooth surface.
I'm not aware of that mechanism. dendritic crystal growth is something we can recreate in a laboratory, so we don't need to invoke an exotic process like lightning. also lightning would melt the rock; in fact there are naturally occurring rocks called fulgurites which are known to be generated by lightning strikes (and they aren't dendritic)
Looks a bit like a codmarble, often found by Scottish mudlarkers, though smaller.....but everything's bigger in the US, ha Thanks for Geology conversations, great show.
The round ball is glass, they were used as a gravity stopper for 18th century water bottles that were being stored or shipped, the neck of the bottle was pinched and the ball served as a stopper 👍👍
Just looked him up. This definitely looks like his style. 23:07. You can barely make out an F, following Bart. Looks like it could say Forbes. Good call
The younger man: If it was done in the 1800s they didn't have conventional paints back then... The elderly man: Or brushes... Da Vinci and all other European Renaissance and Protorenaissance painters: Mind you? Care to elaborate on what we didn't have exactly before the 19th century?! Were we drawing our masterpieces with a lettuce leaf and chicken poo?! Seriously America? Culture and art existed long before your country!

1) Chalcedony rose; 2) a marble; 3) priceless Red Bartifact
That first rock looks like fire agate which can have some flash in it like opal does. There are sites in the Mohave where this can be found.
Not a "fire agate" but certainly agate/chalcedony, which are varieties of micrcrystalline quartz.
I love the painted sandstone! 🎨
I want to see more rock ID videos! I pick up rocks on the beach frequently and have NO idea what they are.
The betrothal one I find them like that and some are fire agates
I think the important thing to acknowledge is: finally someone who doesn't think they have a meteorite LOL

Chalcidony Rose with fire agate inclusions (manganese), marble or glass door knob pull, dendritic art, fused rhyolite.
“Botryoidal”…a word that seeing it spelled out is of little help to pronounce it!🤣. Great content!! Learn lots per episode. Thanks.

Could lightning be involved in the sandstone branches?

@ very interesting.
Ok but what if I really truly believed it was caused by lightning because I feel strongly it to be true? How about now? 🤭😝

interesting! so it may be an antique!
@@tectonic_city yes, mudlarks love to find these bottles , especially with the glass ball still in it👍
The cucumber looking stone looks like a tool which is used to chip stone to make arrowheads and spear heads.
Bart Forbes, Western painter from the 80's.?
Just looked him up. This definitely looks like his style. 23:07. You can barely make out an F, following Bart. Looks like it could say Forbes. Good call
I Don't know the artist but based on the style and colors etc it's not very old.
I knew that last one was volcanic! 😊
First one looked like fire agate, without visible fire. If so, the red would be iron oxide
Preconceived notions die hard
I think it might be a piece of a broken mural, demolished and built over. Fancy bank building mural.
put a light behind the orb How can you see anything without a light!I am alot older than you are!
What if you wet the quartz ball with water to get a better look inside. The outside looks pitted like an old piece of beach glass.
the frosting would still make it difficult
Dude..as a scientist you could have given a better simple explanation of fractals. They are pure mathematics. Not some "hippy" thing
