The microwave I have in my workshop has a defrost setting,I tend to nuke it on this setting for 30 seconds,then let it cool for 2 minutes,weigh it,then repeat until the weight stays the same.Oh and remember on thick pieces of wood you might not feel the heat on the first couple of cycles,as on a molecular level microwaves vibrate the individual cells,which causes the heat and microwaves cook from the middle outwards,not from the outside inwards,so if you don`t do the cooling cycles you can have a fire on your hands where the wood burns from the middle outwards.Remember the higher you have the setting on the microwave the longer the cooling cycles have to be,to be safe I`d double/quadruple the cooling time for each 30 seconds cooked,30 Secs/2 mins,1 min/4-8 mins,2 mins/8-16 mins cooling.This just my way of doing this,just to be safe.
