I did a test this morning in Northern Illinois. The temperature had dropped to minus -24 degrees. BbbRrrrr that's cold.
I used a " SS StarLyte" stove with one ounce of HEET. The second match ignited the stove. The capillary action of the ceramic fibers in the burner portion brings the fuel to the surface where it has plenty of oxygen to ignite.
Once the stove is lit, you can't blow it out. Snuff it out, yes.
