John and I discusses this yesterday. I sometimes do the same thing but use a microwave. the downside of using the microwave is you can't just put the wood in there and leave it unattended. It can catch fire. I do many short cycles. I simply hit the button for 30 seconds and go do something else. come back when I think about it and do it again. If the wood doesn't feel too hot I go to 1 minute cycles. The advantage of a microwave is it dries the wood from the inside out which in theory reduces checking. I have done this a lot on box blanks. I have done an occasional bowl but don't do it often because it takes so long. John's method has the advantage of being able to stack a bunch of blanks in there. Mine is more of very few or even just one.
