How To Boil the oil out of a Norton Crystolon

On my ACE Hardware coarse stone when I use vasoline and oil on it and start grinding. This releases a lot of mud. I believe this helps in cutting. So, I usually leave it and allow it to help with the cutting as I shape the bevel. When done and ready to move on, I'll then clean this off the stone. DM
 
Hi,
I understand you wanted to use water and not liquid oil as lubricant, but
Why did you want to remove the preloaded grease (solid oil)?
As far as I know, the grease doesn't exactly interfere with using water
 
I've decided to go all water stones or diamonds, so I don't really want any chance of the oil in the stone leaching out and contaminating other water stones in my work area, stone holder, or stone storage container. Also, by removing the embedded oil, the Crystolon should retain water better. Honestly, if I were starting today from scratch I would avoid the Crystolon and just buy a coarse SiC waterstone (in fact I just bought a 60-grit Manticore from @FortyTwoBlades, which can be used as a pure water stone). But I already had the Crystolon, and it's a nice cutting stone for the $, so I was trying to find a way to still leverage it effectively. This was a pretty simple way to to do that.
 
I think for me, I would go straight oil stones. And would not care if the stone came pre-loaded. Just use it and store it in a separate box. As I could benefit from it loaded, especially with the coarse stone. I would use mineral oil on the diamond plate as well. Having to pre-soak a stone takes more planning and splashing. In areas where I have to clean up after each use. Plus, the wear and dishing of the water stone eats away
at economy. Just my thinking. DM
 
Tom, it likely was a JUM-3 twin grit. As I usually start out on the coarse side of that stone. Then go to the fine side and strop the burrs off. Depending on what the owner tells me he mostly cuts w/ it. If he says he uses it to cut hay bale twine and castrate calves. Then I'll take it thru that format. DM

That was an impressive looking bench stone David. You are without a doubt the best free-hand sharpener I've ever seen and I'm in my mid 60's. :thumbsup:
