![588. To PRODUCE COLOURED FLAMEs, which, in dark, are very curiously reflected by the faces of the spece tors.—To do this, certain substances are mixed wy burning alcohol. A beautiful rose-coloured flame is p; duced by inflaming four parts of alcohol, poured a one part of muriate of strontia, in a small iron ladles An orange-coloured flame is produced, by burning spii of wine, on muriate of lime deprived of its water of cr tallization.—A flame having a fine green tinge, is ° duced by burning alcohol on boracic acid, or nitrat copper.—A yellow flame is produced, by burning ale on muriate of soda, or nitrate of potass.—NOTE. It sho be observed, that the ladle ought previously to be war and ought to be kept heated while the alcohol is burni The salts remaining behind, after being dried, may; used for the same purpose again. 589. A Mera wich Bursts INTO FLAME WI THROWN UPON COLD WaTER.—Place a piece of potass: of about two grains weight, upon cold water in a bas: —the effect is deseribed:+ at 60. ; 590. EXHIBITION OF THE POWERFUL DETONAT PROPERTIES OF ALL MrxTuREs OF INFLAMMABLE BO) WITH CHLORATE OF Potass.—NOTE: In the perfe ance of experiments with chlorate of potass, proceed » cautiously. Never use more than the prescribed qua ties. Let the hands be covered with stout gloves, keep the mixtures, and vessels containing them, as fé possible from the face. Chlorate of potass must neve kept ready mixed with inflammable bodies ; for such 1 tures sometimes explode spontaneously. Process 1.—Rub two grains of chlorate of potass | a fine powder in a mortar, and add one grain of flo» of sulphur. Mix them very accurately, ‘by well tritu ing them in the gentlest possible manner; and then, ing collected pha’ mixture to one part of the mortar, } the pestle down upon it suddenly and forcibly—a detonation, accompanied by a flash of light, will inste ensue. 591. Process 2.—Let the mixture of the salt and) phur, just described, be wrapped in some strong ]](https://iiif.wellcomecollection.org/image/b22027634_0212.jp2/full/800%2C/0/default.jpg)
