In contrast to an ordinary flame, the reaction is not vigorous and releases little heat, light, or carbon dioxide. The differences between "hot" and "cold" varieties are fairly plain: When a cold flame ignites, it might only kick out heat hotter than its surroundings by a few tens of degrees Celsius, while a hot flame spikes the temperature by thousands. Efficiency goes down at lower temperatures providing the fire with adequate oxygen and good air circulation from an outside source. The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 C). As this is true for all forms of light, its application is seen in fire, or when an object is heated up. The coldest flame color will be black since the flame is so weak that.

Copper sulfate dissolves in rubbing alcohol and produces pure green fire. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 C). If there are no electrons available for bond formation, the substance cannot form a solid. Propane gas, like firewood, contains carbon compounds. Temperature. You can read a lot more about cool flames on that page. Acetylene burns at 3100*C in oxygen while 'Cool' flames, resulting from certain chemical reactions can exist down to 400*C. but a human would still experience that 'cooler' temperature as quite hot.
