Concrete in Flint

[timothy prouty]

I picked up some Flint from Amazon and it has concrete in it will that interfere with frizzen or will it chew up the frizzen thanks

 

[coloradoclyde]

That's impossible...
You can put flint rock in concrete but you can't put concrete in flint...

Are you thinking of chalk?

 

[M. De Land]

Chert and flint are a 7 on the diamond scale so I doubt you will find much that wears out a frizzen any faster.

WELL it look like concrete and that what they say on the net

 

[Coot]

I have seen garden walls in England that were made of flint nodules used just as regular rocks & mortared together. IF your flint came from tearing down such a wall, it may well have "concrete" (mortar) on but not in the flint. :hmm:

I have a few with what looks like concrete on them but I suspect it is the outer covering of the nodule. I have broken open brown grainy covered rocks that were really flint nodules.

 

[Coot]

The nodules often seem to have a very thin white "shell" covering part of them.

Do a GOOGLE search - concretions in rock.

 

[M. De Land]

Yes, this is known in knapping circles as the cortex if I remember correctly.

I suspect it is the outer covering of the nodule

Yep, it's from the outside layer. The nodules look like they are covered in concrete when naturally found, and a lot of folks mistake them for something else.

Flint rock occurs in limestone beds. Your inclusions and coatings are limestone--not concrete.

THANK all's for the info I was confuse because it look like concrete in there it was a light gray I'm just wondering will it still Spark like Flint or should I break up the parts and throw them out I pick up some black English Flint from Amazon it was a 15 lb Rock for 40 bucks

Now the full story comes out.
See above for the appearance of nodules.

Correct!...and the flint is within the limestone or chalk ....not the other way around....also the limestone or chalk is softer than both the flint and your gun's frizzen.

Concrete is a man made material, it is not found in nature.
Soooooo, finding it in flint is impossible.

Maybe this will help....

Here you go, a concretion coated flint nodule.

 

[coloradoclyde]

Which is a "concretion"...The white stuff?
The black stuff?
or both?.... :wink:

 

[Black Hand]

White coating is a chalky substance while the gray/black is flint....

 

[coloradoclyde]

Both are essentially "concretions"....the difference being that the flint was formed by microcrystalline silica filling a void within the surrounding material. This filled void becomes a nodule of flint.

 

[Black Hand]

This is a definition problem:
Concretion was read as Concrete...

HEY thanks for the info I injoy the video :bow:
