This is VERY interesting.
I Always held to the credo, (as verslagen1 said: In general, lighter colors do a better job of reflecting all wavelengths of visible light. Black does a better job of irradiating heat.)
Then, Dave said: “ the wrong kind of paint can also make things hotter (even black) - if they are not good at transferring heat and are applied too thick.”
Sooo with that in mind, (Not Thinking M.C.’s), Would a ’Thick’ Layer, of paint, provide a better, ‘holding’, of the heat? What kind of paint. (Need to be stable at 750-800 f)
Use, two, ‘cans’, (Old Freon cans), cut off two, one a 1/4” smaller in dia that the other. Coat the outside of the smaller one, and the inside of the larger one, with, a ‘heat’ resistance, (2,000 f), ’goo’, (or stove.pipe packing), which is water biased, For melting 50-70 lbs of old wheel weights, on a 175,000 BTU LP burner. It Works, BUT, it takes at least 10 cycles, of heat, to ‘Just’ about 300f, then the goo in-between, boils, and I have to cool down. Want to make them, so they work. with out having to, wait, 6 months, for it to dry naturally, or waste gas and time, to, speed up, the process. (it may be 1/4 - 1/2” thick at spots.)
I make a ‘pot’ up, (with, Frankenstein ’ bolts), then they disappear. Then later, someone tells me, “Oh They Borrowed it”, and I never get it back. Thinking, the, ‘wrong’ kind of paint, liberally applied, then a piece of, ‘(Heat resilience), rope, around the top, ‘may’ do a better job ? And faster ?
