UtilityFlame was originally developed s a firestarter for the military. Unlike the old trioxane that was toxic, UtilityFlame is water soluble, non-hazmat, smokeless and odorless. It’s a gel format that burns hot (blue flame) and can boil water in as little as 3 minutes. Not only that, but it works up to 10,000′ and has a shelf life of 30 years.
