To enable flame generated by combustion to carry out illumination.

The present luminous liquid for illuminator or a mantle for illumination is so arranged to include Aluminum(Al), Yttrium(Y), Chromium(Cr) and Cerium(Ce). The present illuminator mantle is constituted by carrying luminous liquid for illuminator or baking it furthermore. For the purpose of manufacturing method of this mantle for illumination, a support previously formed in a mantle configuration is employed, an organic fiber sheet is laid so as to be formed in a desired mantle configuration, and under this state, immersed in luminous liquid together with the supporter so as to have luminous liquid impregnated in the organic fiber sheet, then to be dried and baked. In this way, luminous liquid for an illuminator excellent in its luminous brightness and ornamentation can be obtained.
