My 2 stones of the day.

[Tchuko]

I bought 2 old wodden boxes with stones in it.
Was funny because the guy was selling them for the antique coffers.
That is what I got.



Stones are 2 inches large by 7.5 and 8 inches.

I followed the instructions here and tried the easy off oven cleaner.
The oil started to thaw almost right away.
I did not let the easy off for long, 2 minutes max at time. This stuff is strong and I only wanted a surface cleanup.
Both stones cleaned up nicely and it took around 10 minutes to remove the old oil on it.



This is the first stone and I don't know what it is. Had a sticker one small side but the Cleanup destroyed it.
Its a porous stone and still smells oils after 2 boilings.

Any toughts on what this stone might be?



The second one got me excited.
Im almost a hundred percent sure its a coticule.
I did not boiled it and its pretty non porus.
The only problem was the banana shape.

So Here goes the lapping time!



The stone made some strange "fractal" slurry as both sides where joining in the middle.
The small "trees" where growing bigger and bigger.



Et voila!

Took me more than an hour of lapping but I think it was worth it.
Can't wait to try it.
I will also try to find a bout to make some slurry.
