Thanks bigspendur, I agree. I should have included advice to the effect that you should only try this with a totally dry stone. Then begin at the lowest heat setting possible and try to gently seperate the stone from the base every 5 to 10 minutes and proceed up the temp ladder with great care.

Before I tried this procedure, I made up my mind that if the stone broke, I would just glue it together onto the new base and lap it until it was flat. That was a fair amount of commitment on my part. Fortunately all turned out well and the stone is intact.

I still have an Ozuku Sunashi Suita to seperate and reglue to a new base. If that one seperates successfully, I will be two for two and count myself lucky.
