I found a website with some interesting information on microwaving wood. This may help explain how it can/can not work for your project: http://www.crcwood.unimelb.edu.au/science/wood.html
They have also provided a pdf you can save: http://www.crcwood.unimelb.edu.au/docs/factsheets/microwaves.pdf

Meilie,
This is interesting. It makes me wonder if it would make the process of impregnating wood with a stabilizer faster and more effective. I am going to try this with a piece of mango that I have that needs to be stabilized before I use it.
Thanks for keeping us informed

mmh:
I use a microwave oven to not only dry small pieces of wood but to also to kill any beasties that might be living under the bark on ” bark on ” pieces.
I generally use several short oven sessions rather than one long session, allowing the wood to rest between heatings.
I just dried some pieces of sweet gum branches that I wanted to leave the bark on. The branch was hollow from rot and the microwave oven helped to some the cause of the rotting.
Of course I only dry wood in the microwave oven when the wife isn’t home!

I used the technique detailed in this link (http://www.woodisfun.com/microwavedrying.html) with great success.
Using the bag also reduce the musky wood perfume that the wifes fail to appreciate.
I have successfully dried 1cm crosscuts of branch without checking following this procedure. also used boiling with same level of success, although it discolour the wood slightly (but in theory you can boil larger pieces than the microwave can contain).
The instructor in the woodturning course I am taking say he freeze the wood in the freezer for 24h and then keep it in the fridge. claims he has zero checking and VERY fast drying time. the freezing burst the cells like boiling and the fridge is actually a giant de-humidifier. as this guy turns HEAPS of stuff all the time, I think he probably knows what he is saying. to save space in his fridge he first rough-turn the bowls.
