Why does my candle have a blue flame?
When a flame does not get enough oxygen, it tends to undergo "incomplete" combustion, resulting in larger exhaust products (usually carbon compounds). This causes the exhaust to look more orange due to incandescence. As the flame becomes more saturated, its color turns to blue.
Who discovered fire?
Homo erectus Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 2.0 million years ago (Mya). Evidence for the "microscopic traces of wood ash" as controlled use of fire by Homo erectus, beginning roughly 1 million years ago, has wide scholarly support. Is green fire hot? A green flame is just as hot as any other kind of flame, except it has color added to it, due to the presence of a "contaminant". The contaminant may be copper, barium, thallium, barium or Niobium, in order for the flame to show a green color.
