Re: Moisture content by oven-dry method - woodcentral.com

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.
