Re: Delamination of roughed bowl blank

Ric Taylor
I used to microwave wood but it has been a long time since I tried it. I only did small pieces, never a roughed bowl.

When something is microwaved, it is cooked/heated from the inside out, the center is what gets hot. What I did was a process that was mentioned on many forums at the time. I used the defrost cycle and turned it on for 20 seconds, then let it cool for at least 15 minutes, usually more. This required many cycles, and with other things going on it would usually take a couple of days. I had success but in the end I decided that it was too much hassle and I quit doing it.

My WAG is that your friend may have used a power setting that was too high, and didn't allow enough time between cycles for proper cooling.
