I was hoping to capitalize on someone else's experience.  I haven't got a 
design in mind yet that I am confident will not involve the fire 
department.  I will keep it on the back burner, though!  :-)

There was a discussion, I think on this list, about just what flash point 
means.  It doesn't mean that it bursts into flame at 105F.  It means it can 
support combustion at 105F.  Below that, you can put a cigarette out in 
it.  Otherwise, parts washers all around Arizona would be bursting into 
spontaneous flame.  At least, this is the explanation I was given.  I am 
not at all confident of my facts on this subject, so don't consider me to 
be an authority.

I do remember a story about someone attempting arson by putting pots of 
gasoline on the stove.  Fire Department arrived to find boiling gasoline, 
but no fire.  Apparently, people smelled the gas.

I did find this on the web, at http://www.ilpi.com/msds/ref/flashpoint.html

Flash Point Definition

     * Flash point is the lowest temperature at which a liquid can form an 
ignitable mixture in air near the surface of the liquid. The lower the 
flash point, the easier it is to ignite the material.

       For example, gasoline has a flash point of -40 degrees C (-40 F) and 
is more flammable than ethylene glycol (antifreeze) which has a flash point 
of 111 degrees C (232 F).
