If the carbon/soot coating is too thick, it will act like an insulator as compared to bare metal. I think in the solar industry, they are using black anodized metals such as aluminum, which is a very thin black coating.
If your scoutmaster was like mine, we kept the kit as clean as possible to avoid getting soot on the rest of our kit, to force us to clean our tins out so we didn't get the squits and thus to engender an attitude of 'look after your kit and it will look after you'. Tins didn't have to be shiny, but they couldn't transfer gunk onto anything else. I agree your scoutmaster probably had a thing for shiny pots. Mine didn't want someone with the squits on a Kinder Scout two nighter.
The blackened pot gains heat quicker from hot coals. It does not work with just a blue flame, there must be a radiant heat source. With a small bundle of twigs to make a brew, the difference could be important to whether your tea is pallatible or not.
I painted the bottom of my snowpeak 700 ti black with engine paint. After painting I shaved 30% of my boil time. Wonder why we're getting different results. Where's Bill Nye when you need him. I wonder if theres a difference between titanium and stainless as far as benefit of a coating of smut/paint. Interesting vid as usual!
I have been waiting for this one. If it makes you feel better I was betting it would make a difference and the pot with the soot would take longer to boil. Still going to try and keep my pot clean but perhaps not shinny! Thank you for posting this.
Interesting, why not use the GSI on the wood stove 5-10 times and boil 2 cups of water..... and try again to see the difference. Most likely will you not have used the GSI only 1 time in open fire.....
However it shows that there is no difference actually for a one timer.
Thanks for presentation, looking forward to a sequel ;)
Great test ever since your black spray paint test I have wondered about a blackened pot from burnt on soot. Next time I will ask instead of just wondering.
The dark color would help pick up more heat from an infrared source. At least, that's what they taught us in fire training. The burning alcohol puts off little to no infrared heat. A campfire will put off quite a bit from the coals. Maybe try it on a different heating source. An electric stove maybe?
Hey Hiram :) Awesome review as i was out yesterday with my Volcano stove and the cup got very blackened. I thought about hmm what is heating up the artic? The shiny snow is reflecting the heat back, and the problem now is that there is so much water there, the water gets a darker color or reflection, heating up the articsea. So i was thinking hm maybe the blackened cup will help get warmer faster while the shiny cup will just reflect much of the heat back to the burner and the ground?
My mess tins are ancient. One is blackened to heck and back after {harumph} years of being used on all manner of stoves and open fires. The other tin is spotless.
500ml of water at 10C on my stupidly fast Nova running full tilt on a kero/naptha mix. Both tins gave a 2:35 to violently rolling boil.
As an aside, with the Nova mounted in a Trangia 27, it takes longer to prime and get to full heat than it does to boil 500ml.
All I can imagine a well blackened pot doing is dispersing the heat. Would maybe help more in a frying pan. Even then, I doubt it would make much of a difference.
I love Sally Ann Shopping, Value Mart, Discount stores, Thrift store, 2nd hand store..shopping rocks.

Every time u heat on wood it leaves another layer.You wont see much of a difference till you get alot of coating on the pot
