Physicist Wolfe (?) said at the turn of the 80’s that there is no ionization in flames. He was implying that this is not empirically verifiable. As any physicist would agree, flames are 3rd state of matter very near the 4th called the plasma state and whether ionization occurs or not is anyone’s guess. Therefore, it is reasonable in this context to say that it does although not at the ideal conditions of thermonuclear fusion of high temperature, high density, high pressure, and long occupation time. Nonetheless, taking the whole universe, it exists almost entirely in the plasma state with occupation time lasting billions of years although stars and galaxies are separated by great distances of matter empty space. This again is an assumption hard to verify by experiments.
If someone struck a wooden cigarette match it cannot be helped but noticed that the hottest portion of the ignited gas is at the tip, defying gravity, but surrounded by cooler, broader, and lower region in the shape of a tear drop. Relatively, the hot part appears bluish while the cool part appears reddish. The blue corresponds to high frequency and short wavelength. The red corresponds to low frequency and long wavelength. Beyond the blue would be invisible ultraviolet (UV) radiation of higher frequency and shorter wavelength. Beyond the red would be invisible infrared (IR) radiation of lower frequency and longer wavelength.
The hottest of all flames would then corresponds to the highest of frequency and the shortest of wavelength in the region of gamma radiation (g) of the electromagnetic spectrum. Taming g would be more difficult than taming UV or IR, since gis one of the component of natural or unnatural radioactive decay, the others being alpha (a) and beta (b) radiation. Secondly, it requires localizing and isolating in the infinitesimal region of space-time but not as pure high energy or high frequency waves but as the infinitesimal separation of matter and antimatter in the forms of positive and negative electrically charged elementary particles.
