130 LANTERN WITH ALCOHOL LAMP AND MANTLE [Cn. V § 213. The management of an exhibition is as for the direct current arc lamp, keeping in mind the general statements in this chapter (Ch. I, § 21-40; § 193). THE MAGIC LANTERN WITH ALCOHOL LAMP AND MANTLE § 214. An alcohol flame burning in the air, is very hot. This has been taken advantage of to heat a mantle to incandescence in the same way that illuminating gas with a Bunsen burner heats a mantle to incandescence. FIG. 72. MAGIC LANTERN WITH THE ALCO-RADIAXT. (Cut loaned by Williams, Brown & Earle}. For the details see fig. 32 and 73. For the best results the alcohol is vaporized, and the vapor burning in a special burner gives the Bunsen flame necessary to heat the mantle. The light is as intense or more intense than gas light with a mantle. § 215. Alcohol supply and burner. — There must be a reservoir for alcohol (95% ethyl, methyl, or denatured). This is connected with the burner by means of a metal tube with a stop-cock. In use the reservoir is filled over half full, but must always have an air space above. Connected with this air space is a force-pump by which the alcohol is put under pressure.
