[QUOTE=alx;1885626]With the risk of reading pickie here, I easily spot two distinct kiita in your group photo. The kanji for "ki" really does mean yellow, but as you have found out, a lot of the stones make a slurry that is yellow even though the stone might looks slightly red or orange. And the yellow kiita stones, their dried slurry usually dries white. The mineral composition of almost all of the Jnats contain yellow sand to a lesser or greater degree. The green asagi have hints of yellow, while the blue and gray asagi show less yellow, but there will be some. Silica is essentially white or clear, it is the clay that is red or yellow or brown, and sand it not 100% silica, Jnats are at the highest 65% silica, the other components make up the "mud" and include titanium and aluminum oxides plus 8 to 10 other components depending on the type of stone. Kiita, true kiita yellow stones are fairly rare, the kiita koppa are just that, bits and pieces. Large full size kiita are hard to locate. And probably more reside in the U.S. now than in Japan because of our active buying these past 25 years.
Hope this helps somehow,

Alex yes a few are easily identified as kiita. Most of mine i think 9 in this pic are actually iromono to some degree so being how I am and wanting to try and understand details that are probably irrelevant since it would be just iromono. I want to try and decipher the base color. After sending some to Steve for his enjoyment I agree that best razor hone is an asagi base color. More green. One or two others maybe also and some are more of a brown which I guess is still kiita at least how most would sell it if there was not iromono in it. I guess I could also dry slurry and see.
And for your enjoyment here is another iromono you may like Alex.
