I often wondered about this, also. My husband, who runs the Electron
Microscope Facility on our campus uses MW and swears by it. If cooking
tissues was truly a problem, it would show up in EM like a sor thumb.
From what he has told me, if your tissues are cooked, then turn down the
wattage. He uses his MW at the lowest wattage possible and in a fraction
of the time it takes with traditional processing, he gets beautifully fixed
a processed tissues... good enough for Nature magazine.
