Drying small pieces in microwave
You can dry lumber in a microwave oven, under certain conditions. 1998.

Is it possible to dry small pieces of wood (1x1x10) in a microwave? I have found some unusual woods that are small in diameter, could be useful for small crafts.
You can dry wood in a microwave oven but there are a few problem areas. First, you need to use very low power to avoid burning the wood. This means a long time in the oven, which means money if the tube burns out. You also need a carousel tray. Then you need to control the moisture content so that it doesn't over-dry the wood. This might be very difficult, as each piece will dry at a different rate. Finally, you need to dry each piece so that it isn't touching another piece of wood--if they touch, you will get burning. So, I guess that the answer is that you can dry wood, but not with much quality consistently.

Comment from contributor A:
Your advice is right. My house burned down because many small pieces of wood burned. Don't leave the oven!
