I once tried forming an F1L set of blades in a microwave and suuceeded in burning a hole in the centre and ruining 2 perfectly good blades.

Joking aside, if the pitch jig is built up, baking in the oven when everything has been well saturated for moulding purposes, it can deform out of shape. Mission not accomplished! I've had this happen recently.

  I find the odor of burning balsa a bit sweet, more pleasant than other
  woods...

  So, yes, I've set fire to a couple of prop blocks both in the
  microwave and the oven. Even with the cup of water in the corner this
  would happen.

  The water is to absorb the energy of the microwaves. It used to be
  relatively easy to burn out the heating element if there wasn't
  something in the oven and a prop blade is almost nothing.

  One thing to be careful about is to make sure that the glue used in
  the form is well dried. I put a block that I thought was completely
  dried (made out of two pieces of balsa with ambroid glueing them
  together), and the heat generated vaporized the solvent in the glue
  which lit up quite nicely. It was a bit funny to watch me try to put
  out the fire without wetting the prop blade.
