Thanked: 202For 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.

Thanked: 3164Stepan - 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.
Regards,
Neil

Thanked: 202Yep. 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.

Thanked: 3164They 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.

Thanked: 202Neil 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.
