French Buhr?

If one may take a few minutes of your time and consideration?

Ohio is a Clay Shale Sandstone State with Glacier Erratic...........

Believe this might be French Buhr? While it looks like Chert it isn't, and it's not native to are area, unless it was from a Glacier Erratic

Local research suggests it came form an area near outside of Paris France.........A nearby Grist Mill existed in 1820 which later became a sawmill around 1852, then a steam mill in 1890 and by 1900 was completely gone.....

Thou this was located about 150 yards up form that location......

French Buhr was used in the millstones which was preferred over sandstone......

A friend of mine thinks this is my best discovery to date this year................Had to move these stones a 150 years back down the river to the road........

That was at least 125 pounds........With the gear at 30..........He pushed for me to bring these out.............

Since a Adena/Hopwell site existed 50 yards away from the discovery he thinks it's Native American.........

They are rough on the other side and not the same thickness.........

Not native American. They look like parts of a broken unused grist mill stone. The cross pattern on one side of the stones looks like the working side of a grinding stone for a grist mill.

They might also be axle housings for the overshot wheel on the millrace.

Or they could be both. A broken mill stone reused as an axle housing when the grist mill was converted to a sawmill?

@ Clay Diggins Thank you for your reply......

Apparently French Burh was loaded on unto French ships as Ballast (extremely heavy for there sizes) jettisoned on the American East Coast and then ships were reloaded with cargo back to France..........

Stone Masons/Millers took the pieces and put them together with an iron ban.........These stones cost more than the property and grist mill itself........Being 1820 it was hauled by a boat wagon to are area.



Support of being parts to Millstone:

Correct match of pieces...........We were having a really hard time with these cuts and irregular shapes.........There must have been a master template
