    So it's either slate or PHIG according to you guys. Difficult to determine and since I'm new to all of this, trying on my only razor doesn't seem like a good idea...

    I did some research on those (Caligraphy sets) and they were made of slate....Making it not suitable for honing...

    Phig, C12ks, etc...are not slate...Slate can not be used for honing.

    But how to be sure? From what I have found, many chinese rock types have been used for making Suzuri's. Also, suzuri's are used to grind down a solid inkbar into small particles of a very specific size and that, in my opninion, implies that they could have certain capabilities one would loke for in a honing stone.

    Hi Zib, I think that is not true. The Frankonian is a slate, the Dragons Tongue is a slate, the back of a coticule (if itīs not a bbb) is slate and can be used for honing,
    slate used to be a very common sharpening stone in the long gone days

    Look at that website, the slate mine that produces the welsh dragonīs tongue

The recipient was supposed to be filled with an ink base and than worked with another stone to release its beneficial components (something whispers "slurry" in my head):

    These are ink stones.
    Often made of slate....

    They are slightly abrasive. Mine is about 5k grit (SWAG).

    The ink sticks are compressed and glue rich carbon black
    and by rubbing the stick on the slate ramp in the pool
    you make ink that you can then brush on paper. They
    are common in Japanese and Chinese art and craft shops.
    Select the best ink stone for the practice of Japanese calligraphy.

    Fancy carved ones are expensive...

    There is no reason not to lap the back of one flat and
    try it.

    EDIT:
    Many slate hones are used with oil.
    Slate like silt stones can be very hard to
    almost soft. They can be sandy and
    coarse or fine as silk.

    Thuringian or Esher or a Mueller are all slates
    of various quality and hardness.

    Many slates and silt stones can
    be further hardened in a kiln.

    A key difference is that slate splits
    where other hard meta siltstones
    need to be cut. But split can be
    thick like a flagstone or thin like a
    roof tile.

    Slate under the felt of a billiard table
    tends to be be coarse and sandy gray
    while the old good black board slates were
    wonderful smooth and fine.

    Color can be blue, bluegreen, red, black...

    You are right Lesslemming, even the yellow-gray Belgian coticule from the Ardennes is slate. A very special, in fact a unique kind of slate with microcrystalline garnets... but still a slate.

    Slate, flagstone... these are very generic descriptive words for meta sedimentary
    stone that can be split. They can be sandy mud stones intercalated
    or just very fine siltstones that split well. And there is no need to split
    into thin roof tiles. Big old slabs are fine too.
