Grinding stone
« on: August 07, 2018, 08:53:30 am »
I want to make a prehistoric point out of a piece of jade.
I acquired some green stone supposedly jade, but not as light and transparent as the stuff you see in museums, in Yucatan Mexico.
It wasnt very expensive and I love the green.

So, now I need something to grind it on.
I saw this beautiful ancient grinding basin, and I would like my grinding basin to be just as beautiful.

What kind of stone is good for grinding my jade with Mohs hardness of 7 to shape.
I read that mostly limestone is just, and then I was wondering how it can grind the harder jade, does it have particles in itsself with more hardness?

There are some different varieties of limestone available around where I live (south of the Netherlands, near the Belgian and German borders). But which do I choose? The hardest? The coarsest?

I started with the coarse first and then went to finer limestone. The limestone I used had sand mixed with it and I kept it wet. I hunted with the jade points the first time I hunted in South Carolina. They will get sharp.

Jade cant be knapped?

I will assess the knapability, but the hear say is that its not the best to knap with.

Perhaps grind it to shape the knap the edge to get sharp? A hybrid point?

Can you not grind a sharp enough edge like with bone points? I know it won't be as "sharp" as a knapped edge but will it be sharp enough for hunting?

It will get sharp enough to cut skin. Pat, don't you remember the ones I had when you, Steve and Tom hunted at Cade's. I shot at those deer with it across the road and the arrow broke when it hit the tree?

Eddie, id love to see some pics of your jade points. Why choose jade? Is ut expensive, is there a specific quality needed to make them? I love the looks and idea, and want to make some also.

Sleek, I left the points in SC and I think Hillbilly has them now. There is different qualities of jade and it's all not expensive. the stuff in Montana is fairly cheap. I have black, brown and green jade. And I made them just to see how sharp they would get.

I needs to be a lot thinner to hunt with. The thing about getting jade very sharp is to polish the edges with water and do not get them hot if using a wheel. If they get hot or dry the edges will pop or crumble.
