In the Dayton Contest forum this year, VE3EJ presented an interesting
method of testing materials for their suitability as RF insulators.
Put a piece of the material, along with a cup of water, into your
microwave oven.  Nuke it for awhile.  The more the material heats, the
less suitable it is as an RF insulator.
