Ochre

Interesting stuff, looking in to it evidently humans have used it for the same thing I have in mind since they got down from the trees. Nothing like rediscovery.

It is a form of "rust" because ochre has iron oxide in it.  To use as a "paint" mix with boiled linseed oil.  I saw this stuff being mined over in the south of France. Parts of Italy are also well-known for this and sienna.   When it is heated it seems to deepen the color; this is then known as "burnt" as in burnt umber or burnt sienna.  Ochre is also considered non-toxic.
A form of this stuff was also used to paint barns and tarps in the colonial days.  It's where the original "barn red" comes from.  Also a "spanish brown".
I'm no chemist but I've picked up a few tidbits in my travels.
Really enjoy your channel!

Looking online I found lots of information on this stuff, its a form of iron oxide, but the most interesting thing to me is its use as a traditional paint in the Scandinavian countries. Fascinating stuff, I have plans for this, but I will have to do some digging in the gravel pile.

Yeah it looks like red clay dirt clods here in SC too. Would probably wash off if used as paint.

I found an arrow head years ago. Showed it to someone that knows more about that stuff than I do. He said it was painted with red ochre. Guess a certain period in time the native Americans did that.

That is RED MUD from the dirt is in clods like that ...here.

Wonder if it would give pine tar a reddish hue ?

I'm thinking baby T Rex droppings!

You could dig up "dog" and send it to the Smithsonian as an "artifact"...lol

Maybe it's Ochre. A red pigment. The Indians used it to pint their stuff.

Red clay and sand mix, maybe .   Thanks
