Talk about context dependence! And reinventing FIRE. Excerpt: "Ordinary, visible fire burns at a high temperature between 1500K and 2000K. Heptane flame balls on the ISS started out in this "hot fire" regime. But as the flame balls cooled and began to go out, a different kind of burning took over. "Cool flames burn at the relatively low temperature of 500K to 800K," says Williams. "And their chemistry is completely different. Normal flames produce soot, CO2 and water. Cool flames produce carbon monoxide and formaldehyde." science.nasa.gov/science-news/science-at-nasa/2013/18jun_strangeflames/
