In a flame, ionization of the air atoms occurs because the temperature is high enough to cause the atoms to knock into each other and rip off electrons. Therefore, in a flame, the amount of ionization depends on the temperature. (Other mechanisms can lead to ionization. For instance, in lightning, strong electric currents cause the ionization. In the ionosphere, sunlight causes the ionization.) The bottom line is that a flame only becomes a plasma if it gets hot enough. Flames at lower temperatures do not contain enough ionization to become a plasma. On the other hand, a higher-temperature flame does indeed contain enough freed electrons and ions to act as a plasma.
That is what a simple google search got me. Maybe take your own advice.
