I know that there are many people who have had good luck with with the new starlyte stoves designed to work with the Caldera Cone. I found when I used grain alcohol rather than denatured alcohol the bottom of my evernw 500ml pot was covered in soot. The burn appeared to be quite aggressive with lots of orange flame.
Use of the original Trail Designs 12-10 also resulted in quite a bit of orange flame, however, no soot was produced on the bottom of the pot.
There are those who have said that adding a small quantity of water to the everclear can result in a cleaner burn. By chance, has anyone managed to get clean burns this way on the modified startlyte?
