A Few Stones Arrived Today

[Gamma]

One of 3;

A very very - very - hard Nakayama Kita. Hard to the point where lapping it was notably difficult.
I'm not done lapping it here - I snapped this when I stopped to test the stone. I'll let it dry now so I can inspect the top.
First test - it's uber-hard, shockingly fast, and very very fine.
The 2 far corners had to be angled, I didn't want to lose 4-5 mm of the top to clear the chipping.
The top is consistent all around. Tthat patterened portion in the lower left feels just like the rest of the stone.
Which, at the moment, is quite glass-like.

Nice stone. How big is that thing, looks huge for some reason.

 

[Gamma]

The long side in front is about 7.5", a bit over an inch thick.

 

[Bayamontate]

Iromono madness, cool stone.

 

[gumbo]

It looks like a coticule on PEDs

 

[Brooksie967]

You get the coolest looking stones. Nice!

 

[Gamma]

Thanks everyone

Nelson had it right.

In this stone, That red is called Iromono, which means beautiful color.

 

[Obiwan]

Very nice looking stone. Congrats on the new addition.

Thanks everyone

Nelson had it right.

In this stone, That red is called Iromono, which means beautiful color.

Is that because the Colour is there without the presence of su or being a suita?

 

[CanonSterVa]

Very nice.
Will surely have to venture into a new realm of stones...
One Day!

[jpcwon]

Very nice!! I'll be interested to see how it performs!!

Alex - for the early work, I'll be using the typical stamped and unstamped Mikawa Nagura, along with Tsushima and Chu Nagura.

For a Tomo - I have a few to choose from. If you look in the background of the photo above you'll see two that are stacked that have the number 4 on the ends. I used the smaller one last night - it's a very good match. Both of those Tomos are salvaged pieces severely cracked Nakayama Namito Kita Kan Awasedo. I still have to finish rounding off one edge on them but they're useable now. The smaller #4 Tomo is just a hair softer than this new stone, but it's also hard enough to bring up particles from the stone.




My understanding is that Iromono is purely a color-centric characteristic that is most often associated with, but not exclusively to, the Tomae strata.
The presence of Su, whether the stone was a Suita or not - wouldn't play into it.
I had a Nakayama Tomo with Su, i don't believe it was a Suita, but it was definitely 'Iromono'.

Many of the Jnat characteristics are a pattern of some kind - Momiji and Renge - oak leaves and lotus flower, respectively.
Goma - small black dots, Nashiji - looks like pear skin.

Iromono though, is just a color splash. The word also translates to 'colorful laundry' - so when thought about in an abstract sense the characteristic can be visualized more easily. I imagine kids clothing tumbling around in a washer.

What is interesting here - is that the red coloring in the two corners in front both have more of a speckling than a splash-like presence
In the center of the stone, a more vaguely shaped splash is present, but the camera didn't pick it up.

 

[Brooksie967]

Thanks for that Gamma, appreciate it. The speckling is what made me think of renge or momiji specifically rather than just iromono but i totally accept that explanation!!

 

[Gamma]

I haven't ruled out the possibility of there being more to the story yet. Often, with lapping, new things are revealed.
I haven't louped the top yet, there seems to be Goma present at the corners. There could be some 'Su' also.
Most of the stones I get come without lengthy descriptions, stamps, etc - I'm kinda on my own to figure stuff out.
My experience is somewhat limited - so any outcome is possible.


Here's the back of the stone.

Here's the bench-top during the intial testing phase.

The other two large-ish stones are Iwatani - one Kita, one Asagi. The small reddish one is a Hakka Murasaki.
