Thread: clean oil stone maybe Charnley

Hello,
I have bought at a flea market in U.K this stone...

I think it is a Charnley but i'm not sure... confirm at this regard will be appreciated...it is very smooth and hard...
The stone was having strong kerosene smell..at home i washed it with very hot water and soap for dishes...now it absorbs water and seems to be cleaned...but still i have doubts about real color of this stone...maybe is required a more aggressive cleansing treatement before lapping? If so what can i do?

lap it flat on one side and then the color of the stone can be seen better.

I can't really tell what color that is either... Charnley's that I've seen are green with red inclusions, but I've heard they can be greyish as well (lower quality Charnley's?). What color is that one?

Is it just me, or does that look like wood?

That looks alot like pics that Sham posted of his Charnleys. The photo made the stones look white with the red/purple streaks but when I got one of them from him it was a greenish color. Whatever it is it is a beauty. Howard once posted that oven cleaner was quite effective at getting old oil out of a stone.

it is most likely charnley. Of course what we are seeing from the picture.

I have already tryed lap one smallest side with abrasive paper...main color is always the same: olive green...and of course, this stone has veins or stratifications that make it similar to wood...

olive green indicates a Charnley. Nice piece.

The very best substance for cleaning oil is Vulpex Liquid Soap. It isn't a particularly dangerous product, but it is best to wear rubber gloves when using it, as it can dry your skin out very quickly.

FYI, it is the grey coloured Charnley Hones that are generally considered to be the most desirable, as it is this colour that is typical of stones from the Whittle Hill quarry which was one of the preferred sources. The greener stones are often prone to hard inclusions which can have an adverse affect on an edge.

Kindest regards,
Alex

Thanks for pointing out my mistake, Alex. I've edited my previous post.

I don't disagree but just to point out that the olive green/purple streaked CF I have is a great stone so some of them may have inclusions and some of them do not.
