At what temperature can ethanol be considered dangerous?

Hi everybody, I’m doing a science experiment where I’m pouring 100% pure ethanol into a bottle, placing that plastic bottle into a pot,and placing the pot onto a stove, and raising the temperature to 30-40 degrees C. I’m not sure if this is safe, b/c the bottle says that pure ethanol should not even be exposed to sunlight for long amounts of time.
please consider your response carefully because this is a potentially dangerous experiment, and I am taking all responses seriously.
Hmmm……I agree, but I am taking precautions:
-hot plate (plastic, no fire/sparks/etc.)
-under a hood (ventilated)
-fire-hazard gloves (thick, does not catch fire)
-glassware

    Oh…NOT a good idea.

    The flash point of ethanol is 13C. Heating it beyond this in a closed container may cause an explosion even in a water bath. Any time it is above 13C, the vapors can ignite with very little provocation.

    Please do not do this…I do not want to read about it in the paper or see it on the news.

    At ~55F (13C) your plastic pot will explode. If it ever reaches 30-40 degrees C, we will all know EXACTLY WHO YOU ARE because we will see you on the news, and shortly thereafter you will receive a “Darwin Award” for having blown yourself up and thus preventing the passing down of whatever genes it is you possess that make you oblivious to the obvious risks of deliberately heating fuel beyond its flash point!

    When is your wake?
