The incandescent gas burner consumes the gas with a non-luminous flame in which there is no decompo- sition of the hydrocarbons, and the heat produced is employed to raise to incandescence a foreign body introduced into the flame. The difference between the amounts of light produced per cubic foot of gas by the two styles of burners is thought to be due to two principal causes. In the first place, the sub- stances of which the best incandescent bodies are made, namely, thoria and ceria, in the ...proportion of from 98% to 99% of thoria to from 2% to i% of ceria, convert a larger proportion of the heat into light by converting the heat into the light rays which yield the greatest illuminating effect for the smallest expenditure of energy, that is, those forming the portion of the spectrum in and around the green, while the carbon particles in the luminous flame give off principally rays BURNERS AND FITTINGS. 493 falling in the red and yellow portions of the spectrum, the lighting value of which is comparatively low.
