I have a 5k chosera absolutely love the choseras..My 5k is the older type not the new pro series..I have it for about 4 years. Have used it on many razors. .Its really starting to craze where i can actually feel it woth my fingernail..Do the new pro series present the same problems?
Good to see you posting again,,,,,,,,,,,,,,,,,:tu
Can't answer your question, as I don't own any Choseras,,,,:shrug:
If left wetted for a prolonged time, yes, they will.
What is crazing? Glazing?
Fine cracks in the surface.Quote:

I believe the magnesium binder is unchanged between the former chosera and newer pro versions. I think the best thing to do is to lap it down bit and see if that solves it.
I don't think the choseras need more than a minute of soaking and in this instance now that it already is crazing, I would keep the water exposure to a minimum by just spraying the top with wate and then wiping it with your hand to uniformly distribute it. Then keep on repeating as necessary.
That happened to my sigma II 13k, it is no longer with us as it fell apart when I let it dry out too much. It was my mistake as I wasn't supposed to soak the hone for prolonged periods. I hope yours is salvageable.
I returned a 5K to the vendor for crazing. They replaced it and now the new one is crazing. Weird, Of the 4 Choseras that I own, the 5K is the only one that has crazed. You cannot feel the crazing with your fingernail. I'm not going to try and return the 2nd one. I have never soaked it but splashed and went.
My only experience with crazing was with one of my Shapton pros that was left on a sunny shelf too often thus drying quickly.
I now put them away wiped but not dry.
My 1k was left in the pond overnight once, it didn't craze, just sort of melted into goo. It wasn't severe enough to cause any issues, but I learned my lesson. I just recently added the 3k, and have not had any issue with that one.
I hope you saved the goo!
There'd be a lot of good slurry in there!!!
My 1K Chosera did craze a little after a too long soak. It also turned a white color on the face over the down side when I let it dry on edge after a soak. Still usable but not so pretty.
Some factory instructions said not to soak them.

I never soak them. Just wet them on top and let it sit for 15 mins. My 12k got plain crazy after a soak once. Twisted it!
It did recover, however!

Ouch, never seen one like that before. You can seal the sides with some lacquer, just like a J-Nat and it will be fine.Quote:

i never had such problems with resin base stones and my cheap taideas ha ha ha
Just pulling a little bit ....
The picture of the defective hone indicates delamination, not a crazing effect. Both types of stress deformation can “possibly” be the result of a curing issue (or lack thereof), after manufacturing. Try sealing the sides like Stefan suggested before using it again.. IMO Good luck.

Thanks, the more I thought about it, and I haven't actually thought about it very much as the honing surface is free of defects, I decided to send the vendor the pics...all thanks to this thread. He thanked me and said he would send the pics to Naniwa.Quote:

I use the older Chosera stones used them for a few years, I personally never soak them run them under the tap spray while in use I then dry them thoroughly after use then store them in a cool dry dark enviroment, never had any issues with crazing.
