        Just wanted to note that not all waterproofing increases
flammability; I had occasion to do similar tests on commercial materials,
and found that the CFAI-84 fire-retardancy spec is worth looking for when
selecting tent fabric.
        One sample of 10oz I worked with simply refuses to take fire (I used
a torch), even when saturated with wax (like a candle getting knocked into
it), dripping with alcohol (the alcohol burned off leaving the sample
untouched). Sulfuric acid didn't touch it, and boiling it for a half hour in
water did nothing to the waterproofing; water still beads-up on the sample.
        In fact, the final test was to fire a crossbow bolt at it; the shaft
went thru, but it stopped at the fletch. :-)

        Bottom line: If your tent fabric burns at all, take a fire
extinguisher with you.
