>>1426557The color black helps transfer heat better than any other color. White is the opposite, in that respect, and helps hold heat a but better without transferring it. This is why most fridge/freezers have white sides and black heat exchanger coils on the back; to reflect or release thermal energy better, respectively.
Thus, if the cooking vessel is any other color than black then it will help to paint it black a small amount. Though, contact cooking where the cooking vessel is physically touching hot coals won't be enhanced much with black paint added. Anything that has an air gap will be enhanced by black paint. Use matte black.
>>1426522I don't have anything, I like more than anything else, in my pack. I think that is due to the fact, everything in the pack is extremely useful and is normally used to its fullest extent every time I go out with the pack, (except the 1st aid kit of course, never needed it yet.)
