    Does anyone know the burning temperature of denatured alcohol? I was able to see the "autoignition temperature" for ethanol on wiki as 363 degreen C, but is that the right temperature for burning standard denatured alcohol? The reason I ask is that I am contemplating using JB Weld for a stove project, and want to be sure that it will not light up.

    Thanks

    1) it depends upon how close the flame is to the weld joint. I believe that JB Weld is good up to the mid 400 F range. I thought that the hottest part of the flame was closer to 1400 F but don;t quote me on this. Near the start of the flame, it can't be that hot as aluminum softens (melts) below 900 F (I think).

    2) the bigger issue to me is that I have seen JB welds degrade when exposed to alcohol over a prolonged period of time. This may be due to the fact that most aluminum cans are coated with a varnish and you really don't make a metal to metal bond.

    My 2 cents – Jon

    Interesting. I saw the recommendation for JB weld on zenstoves. I am trying to make the basic side burner stove, and they suggested silicon or JB weld. Sounds like this is moving towards the MYOG forum, I will repost there. Thanks!

    Aluminum melts at 800F but the flame tip never contacts the metal.
    The JB weld is used ONLY at the base of those stoves where it doesn't get very hot.
    If you want something that will grip the aluminum and still take the heat-look into the red high temperature RTV silicone. Available at automotive supply stores.

    Use it only at the bottom and don't expose it to alcohol until fully cured.
