- I do a burn/boil test of two of the 1/2oz tin burners compared to the 1oz round burner.

Enjoyed that thanks for sharing 👍
👍👍👍 .. interesting.
One wonders what is the 'physics' behind the test results. Flame surface area vs depth of container, etc, etc.
The round tin will obviously burn longer due to it's configuration, thus giving the water time to get up to the boil.
Interesting to know would be at the time that the two square tins took to get the water up to it's maximum temperature before running out of fuel, where the round container would have stood, water temperature-wise.
I think that it's probably a factor of 'efficiency of shape and volume' .. surface flame area and depth of the fuel reservoir feeding the flame, which has an effect on heat output and burn time.
Must do some 'mulling' 🤔 over this one. Thanks for sharing .. take care ..
I was thinking 🤔 along the same line as you. I believe that the extra surface area of the rectangle tins combined with the shallow depth allows too much of the fuel to vaporise and essentially escape from the tin. It’s almost as if the flame can not keep pace with capturing the evaporation of the alcohol, which has a very low boiling point
My stove is a little taller. 1oz tin with 91% isopropyl did 2 cups 64f in 8 minutes. Pretty similar results. Nice part is you can shut it down and save the remaining fuel or keep on cooking. It will burn for 15 to 20 minutes. Beer can stove was under 6 minutes but only burned for 8 minutes with 1 oz of fuel. I have tried many different designs and I am going with the 1oz tins.
I use Klean Strip Fuel denatured alcohol. Have you compared Yellow Heet to denatured alcohol in boil test? Probably not much difference but might make in interesting video ...
I watched a comparison video and Yellow Heat performed a bit better then Klean Strip, also, at least in my area, Yellow Heat is cheaper.
Here's the video, really good.

Nice! I'm wondering if it's the difference in hight that means the two half ounce tins don't boil the water whereas the round one ounce does? Maybe there's an optimum distance to get maximum heat output?
Cheers for testing the two together.
Could be, I'll have to try rising the small tins up and see what happens.
Yes. You need at least an inch of space. I prefer 1.25" to 1.5".
