what the! why can't you give answers answers.com
Glowing gases observed during combustion is called a "flame."
There is a lack of oxygen in the flame itself (most probably because of the air holes in the Bunsen burner or of your burning device) this effect would create a luminous flame (better known as a yellow flame). A kind of flame that does not burn as hot as a non-luminous flame (better known as a blue flame)
One should work far enough away from the flame to avoid contact with the flame itself. A person should have enough distance from the flame to keep loose clothing and hair safe as well.
When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.
Because methanol is flammable you need to move it away from any other sources of methanol and other flammable materials before igniting the desired container.
So what is really the answer?

Some precautions are to not wear loose or baggy clothing that could fall or blow into the flame; don't have any combustible or flamable items or chemicals nearby; don't stand down wind of the fire if it is windy; don't get close enough to get burned; never leave an open flame unattended.
Electrons are excited to higher energy levels and their emissions are observed.
During combustion, energy is released. Some of this energy takes the form of light, making the flame visible.
You have to install any antispam program with thoroughful filter adjustment settings.
Sodium of course...
Emission spectrum of the elements placed in the flame. The flame test is usually applied when Sodium, Potassium or other such metals are thought to be present since they give a very noticeable result - Sodium gives orange colour to the flame (as it does to sodium street lighting!) - Potassium gives a lilac colour etc

it burns white, but when mixed with potasium nirtate, it burns purple/violet
Because the flame itself is the hot gas.Every gas(hot) have a tendency to go upward.
