Thought I'd better share this, so no one burns there house down. I was drying some spalted maple in my microwave on Saturday, and had a new "dumb Swede" experience. By the way, I've done this before, with no problems. Long story short ( I'll leave my wife and daughter's comments out) several of the pieces caught fire. I had the microwave set on high - won't do that again - 20% next time. I lost a couple of nice brush handles, a knife handle, and a couple of pen blanks. It was damn nice spalted maple, too! Luckily, no real damage to the microwave, or the house, for that matter - although it still smells a tad smokey. So, new rules - don't leave the microwave unattended and don't do it on high. Still not sure if it just got too hot, or if there was some resin in the wood that caused it. Another unexpected learning experience.
