This is really a fragment off a large coral head. The ancient chipped surface is facing us and has been stained by the enviro over many years. All Suwanee River Florida. Oh yeah,many heat treated.
Black coral out in the middle of the river stuck in the 'ancient' black muck. The stain is deep,sometimes to the center. Arrowheads are surface stained. Maybe 1/16 of an inch deep depending on porosity
Because they were exposed to the black muck less years probably. This one was tumbled longer to remove the outer coating to the 'black' base color. Red=heated
This is out of focus. It is a beauty. The high spots were ground of w/Chinese grinders to expose the butterscotch base color. Red=heated. It is 8 ounces...
This color comes out of a life in the high sand and/or white clay above the staining influence of river water and accumulated black mucko. Not heated
It is pure like a virgin.
This is a another from sand and is pure till i heated it to 600F and brought out some redness in the skin.
All i can say is it was heated. That base color is about the norm before the enviro injects iron salts or 'muck of dung' into the coral silicification. This one did not absorb well due to low porosity(dense as hell)
In the south we would rudely say "You Ugly" before getting into a fight. Well this is ugly
I have learned to collect the splinters. They are well colored and hardest of the hardest. Saving them for jewelry.
This one is sawn so you can see the base color. I am seeking other base colors than the common white. Notice the corallite texture runs throughout.
sexy black morsel not heated
heated got orange
This is the initial slurry when tumbling the white coating off. It is soft limestone till it hits the silicified white limestone. No grit used and tumbling for about 2 weeks. Then segregated by coating thickness.
The coral on the left has the original skin. On the right is partially tumbled. This coral comes from a location about 150 miles further south. But all the coral has skin like that in the left bucket.
