Potassium ions produce a lilac flame in a flame emission photometer. The presence of potassium in a sample can be detected by observing this characteristic color emission when the sample is introduced into the flame.

A red flame has a lower energy than a blue flame, if the color arises from the photon radiation of the flame itself due to the flame's temperature. However, some inorganic ions emit red light when introduced into blue flames, and this kind of red flame does not necessarily have a lower energy than the original blue flame.
When hydrogen is introduced to a flame, it burns with a pale blue flame that is almost invisible in daylight. The flame produces a lot of heat but relatively little light. Burning hydrogen produces water vapor as a byproduct, making it a clean fuel source.
It is an American selection, found in Minnesota, of Salix alba, the white willow introduced in the Americas.
If nothing is added to the mixture and no flame is introduced externally it is called spontaneous combustion.

When the air hole of a flame is opened, more oxygen is introduced to the combustion process, resulting in increased fuel burn rate and heat output. This typically leads to a hotter flame temperature due to the enhanced oxygen supply supporting more vigorous combustion.
To safely put out a sterno flame, carefully cover it with a metal lid or snuffer to cut off the oxygen supply. Do not blow on the flame or attempt to extinguish it with water. Wait for the flame to completely go out before moving the sterno container.
