Hello, i see you joined in Jan. I am sure you picked up on some of the etiquette here? If you would like some help then you need to give as much detail as possible. A far pic on a stone does not provide much information with the caption "ID Hone Needed"... Tell us where you got it? Get close up shots after you clean it, with and without slurry. Does it feel gritty, or fine? Glassy?
Right now i can tell you it is a rock on a board... Black rock... Old board..
Thanks I am a newbie at all this, I got this stone on e-bay for $35, it is a very old stone, very very smooth and is a whetstone, will this help some?
It's all good. Thanks for mot taking offense to my well intentioned ribbing. Can you get a close up of the slurry?
Is it soft or hard? does it have oil on it? smells like oil? slurry color?close up of the stone itself? did you lap it? Dimensions?
Sorry for the slow response, it procuces a nice creamy off white/brown slurry, no oil smell just earthy. I have gotten other responses from other sites that it may be a Charney Forrest hone, never heard of it, thanks.
I very much doubt that this stone is a Charnley Forrest since they are usually green with other colors and use with oil,Quote:

This photo is not very good, the stone is greenish in color but not hard to produce a slurry and I have not used oil. thanks. The stone has real fine reddish streaks.
From what i heard a CF produces a pinkish slurry!!Quote:

Post more pics!!Quote:

Are you the owner of the stone? The photograph that you have posted looks remarkably like that of a seller.
If so, post pictures once lapped, with clarity, wet, dry and with slurry. Otherwise its like posting a brown paper bag and asking what kind of liqueur is inside.
for a I.D you'll need to post better pic's
Wrong. I does not produce pink ish slurry. Even if you slurry just red streaks in them it is not pink.
Ok then well talk to Modine cause he clearly stated in a post that it does slurry to a pinkish color!Quote:

Adrspach (Stepan) probably has more Charnleys than any other member here. He has even quarried his own, which is quite awesome seeing the quarry has been shut down!
What you might find is that the slurry can look as though it has a pink tint to it where there are red streaks and or blotches in the rock, as the slurry is really a milky white colour and not fully opaque; the red features of the rock exhibiting an illusion that the slurry is pink. This has been my experience with one sample.
Good information, so its ok to say that the slurry can be pink like Modine said. Nevertheless it is not our quest here on this threadQuote:

Unless there is more information it will be quite difficult.
I suspect it rather depends on the actual stone!Quote:

I have taken numerous examples with just a few streaks of red in them, but these ones don't seem to influence the colour of the slurry at all - which is only sensible, as the red must represent a tiny fraction of 1% of the surface area of the hone. Most of the ones I have tried fall into this area.
However, I have a few with enormous swirls and streaks of red, even large circular areas of red, and these do give a pinkish/brownish tinge to the slurry - which again is only reasonable, as the ones of this type I have used would have around 25% or so of the surface area made up by red patches.
If you abrade a red brick, you get red brick dust, common-sense, no?
One type I used to have was a softer variety and gave a poorer finish than the others. It had speckly bandings of red and some swirls of red. I didn't expect the slurry to be much different than usual, but this was decidely deeply pink/red. Upon further examination the red areas were much softer than the green areas, so I suppose the green particles in the suspension actually abraded the red areas more, bringin more red particles into solution than would otherwise have been the case.
Everyone seems to forget at times what we have all agreed about natural stones - they each vary from other examples of the same hone, making each one somewhat unique, so only very broad outlines can be given: outlines, not rules!

For some reason when I was playing in them when I was cutting and grinding with my grinder specifficaly in red/brown parts there was a lot of red dust. However when I tried same place to make slurry it was just white. Why I do not know.
I do know hone hwich does make red slurry and is green with red banding where red is very soft and in the quality of edge can be bellow CF.
lacking better pictures and a test drive
my guess is that this is a carborundum hone
from the late 40's or 50's perhaps a fine one
but not razor fine. My dad and the farmer
down the hill had one a lot like it. Berrys
hardware had a bigger one by their register.
Perhaps one that has been used with oil for a long
time... (does water soak in or run off). The oil is
perhaps gummy almost varnish like.
Do audition it with some steel and see how it
acts. My wager is that it is a worthy
hone for pocket knives and kitchen knives.
If it is well seasoned, clogged and glazed with oil
it could hone a razor in a pinch with one or
two wipes down the length.
Stepan - I think the one you are referring to is a Moughton - alternate red and green bands, quite soft, unmistakable smell (a bit like wet plaster) and a fair bit below the "grit" (...I know, I know... :) ) of a CF - perhaps equivalent to 7k - 9k. It is surprising to see how tinged with red the slurry is, even with a less than 50/50 relationship between red and green stripes.
I think most slurries look whitish due to the opacity of the material that is in suspension in the water - you aren't getting that overall polished effect that reflects the light evenly, but a lot of finely divided matter that bounces the light back in all directions. I have seen one or two CFs that made such a copious amount of red slurry it looked like blood in it, but they had very soft red areas with black centres. I would imagine that red and green being opposite each other in the colour wheel that the slurry would go a milky brown colour (red+green=brown), but like you the majority of the CFs I have tend toward a milky murky green tinge, probably because there is so much green matter as opposed to red.
I have cut rubbers on a large water-cooled diamond wheel and have noticed the red spray spreading when going through the red areas, though. The water probably helps here, making the red particles more reflective than if they were just dry dust.

Neil
Yep. Spot on.
Sorry I am too simple to understand all those posh words. I only go by my limited personal experience.
I am very interested to see one of those soft CFs. Please let me know if you will get across one.
They are only words, Stepan - if they don't get my meaning across then they aren't that clever either. Now, what you do: locating the quarries, visiting them, getting your own bits of rough rock and turning them into hones - that's clever.
Neil words are fine but my knowledge is not great. I am sure people already noticed that English is not my first language. That is also the reason why I am not realy enjoying academic research about hones and would rather walk few miles and look for the knowledge manualy. I am sure you know what it is when you sitting in ruin of old slate dressing works and imagining what those workers used to do around you or when you find at local carboot sale somebody selling part of rockery or a ball of crud which fits to what you looking foor. That is where for example my Moughton is from.
