Thread: Shapton 15K question

I just want to add that I soaked my 12k shapton in water overnight with some other waterstones and I got a big surprise. I know that shapton says the stone will not absorb water, and soaking is not necessary and is ineffective, but I had to experiment.

The results are that after soaking, much (slurry) was washed off. when I pulled the stone out of the water, I had a very fine slurry on my hands and when I rinsed the stone under running water, I could see some slurry in the running water. when the stone was totally clean under running water, I had a very course texture. I will now have to lap this stone again.

Also this stone took the diamond edge off of my DMT. The DMT is now worn out. I guess the ceramic used in the shapton is too hard for the diamond impregnation of the DMT.

I will not purchase anymore of the shapton stones. I am sure I am doing something wrong but this stone is not for me. I will stay with my nortons and belgiums.

I am very interested in other members opinions.

Was the 12K stone you have the half stone? If so, I agree bad stone. I had one, I threw it away.

Don't let that stone mar the pro series of stones, these are very, very good.

Actually, due to the binder in these stones, you are not supposed to soak them at all. Its not that it isn't necessary, it isn't recommended at all, for the reasons you described below.

I have never heard a "horror story" from a natural unless, by some reason, the incorrect natural was chosen.
