- Microwave drying is a fine art, and not always successful even with infinite
- patience. Some woods just don't seem to take to it. But here's what I do
- with (usual) success:
-
- Get two large zip lock plastic bags and put your piece inside one. Close
- the bag.
- Put it in the microwave on the *lowest possible setting* and zap it for 30
- seconds. Take the bag out and look for condensation on the inside of the
- bag. If none, zap it again for 30 seconds. (It helps to keep a log of your
- power setting, time, wood species, and condensation results.) Keep this up
- until your have condensation that totally obscures the visibility of the
- piece inside, or until the piece feels almost hot.
-
- Once you get to this point, open the bag, turn it inside out, and transfer
- the piece ot the second bag. Let the first dry for a while as you use the
- second. When the piece has cooled to normal temperature, repeat the whole
- process. Continue with this sequence until the condensation stops after
- a period of cooking that normally produces condensation.
-
- As you gain experience and build your log, you may be able to increase
- cooking time (and/or power) to speed things up. But start slowly
- at first, and I'd suggest cooking a waste block of the wood species
- you'll be turning so you don't wreck a good piece as you gain experience.
-
- GOod luck.
