Thread: Chosera 1k drying time

You do not need to worry about it, it will not cause any damage to the Chosera stone. Just store it in a safe place and you're good to go =)

Any chance the stone dried too quickly ? In the sun?, Air con ?

My 320 grit Shapton Pro is always mottled with water stains. Hasn't hurt it yet but my 12k did get some hairline cracks. Pretty sure it was drying in a sunny area.

My shapton gs 16K has developed those checking cracks/lines. I can't feel them, so I just take it as it's part of it's aging process like our lines & wrinkles.

Three days after the honing session

Soaking Chosera's will ruin them.

I can tell you by experience that soaking them for a couple of hours & even overnight...will NOT ruin the 1K. Hasn't ruined mine in several years anyways.

The Chosera's are naturally very thirsty stones If you don't at least run them under the tap for a minute or two just spraying them with water seems to have little effect they need water to work, In my opinion the most important factor is how you dry them out I clean mine off with the Nagura stone supplied or lightly lap with a diamond plate, run under the tap wipe them dry and then store them in a strong cardboard box with holes drill in it and leave in a cool dark place.

Here is what this seller of Chosera stones says...

http://www.fine-tools.com/naniwa-chosera.html


"IMPORTANT NOTE on storage and lubrication: Chosera sharpening stones are bound with magnesium and so have more cutting particles per unit of surface than resin-bound stones. But magnesium-bound stones are much more sensitive to prolonged exposure to water as other types of stones. So Chosera stones should NOT be left to soak in water for prolonged periods and must be stored dry. If this advice is not followed the stones can develop hairline cracks or the binding material can be leached out of the stone. It is more than enough to pour a little water on the surface or briefly dip the stones in water, they do not need to be soaked. If you are not sure that you can keep this always in mind, perhaps because you have a number of different kinds of sharpening stones, it may be better to opt for the more tolerant Super Stones."

It is on the Internet, so it must be true. I wonder why my stones haven't evaporated. ..Or maybe experience doesnt count.

My advice Scott is to just give it up, I have come to the conclusion that my Naniwa hones be it Super Stones or Chosera are "Special" perhaps yours are too...

I will contact the manufacture and get their advice and reply once I get it. Not trying to get everyone pissed off. Just trying to give fact based answers. The experience of one or two is not enough of a sample to make a fact based statement. I've seen enough threads about cracking Chosera's to take the side of caution and try to find more info.
