Using 1.5oz of Crown brand denature alcohol, I got a burn time of 26 minutes. As the sun fell, the lack of lights outside allowed the alcohol to show flame without any salt added. All the flame came out of the jets. I'm make another where I'm add the walls of the fuel cap a little higher so when I fill the jets with alcohol none of the alcohol drips down the side and onto the ground.

It is one of the blessings of wilderness life that it shows us how few things we need in order to be perfectly happy.-- Horace Kephart
