Place the carmine into a pint bottle, and pour on it the ammonia; allow them to remain together, with occasional agitation, for two days; then add the rose-water and esprit, and well mix. Place the bottle in a quiet situation for a week; any precipitate of impurities from the carmine will subside; the supernatant "Bloom of Roses" is then to be bottled for sale. If the carmine was perfectly pure there would be no precipitate; nearly all the carmine purchased from the makers is more or less sophisticated, its enormous price being a premium to its adulteration. Carmine cannot be manufactured _profitably_ on a small scale for commercial purposes; four or five manufacturers supply the whole of Europe! M. Titard, Rue Grenier St. Lazare, Paris, produces, without doubt, the finest article; singular enough, however, the principal operative in the establishment is an old Englishman. "The preparation of the finest carmine is still a mystery, because, on the one hand, its consumption being very limited, few persons are engaged in its manufacture, and, upon the other, the raw material being costly, extensive experiments on it cannot be conveniently made."--DR. URE. In the _Encyclopedie Roret_ will be found no less than a dozen recipes for preparing carmine; the number of formulae will convince the most superficial reader that the true form is yet withheld. Analysis has taught us its exact composition; but a certain dexterity of manipulation and proper temperature are indispensable to complete success. Most of the recipes given by Dr. Ure, and others, are from this source; but as they possess no practical value we refrain from reprinting them. TOILET ROUGES. Are prepared of different shades by mixing fine carmine with talc powder, in different proportions, say, one drachm of carmine to two ounces of talc, or one of carmine to three of talc, and so on. These rouges are sold in powder, and also in cake or china pots; for the latter the rouge is mixed with a minute portion of solution of gum tragacanth. M. Titard prepares a great variety of rouges. In some instances the coloring-matter of the cochineal is spread upon thick paper and dried very gradually; it then assumes a beautiful green tint. This curious optical effect is also observed in "pink saucers." What is known as Chinese book rouge is evidently made in the same way, and has been imported into this country for many years. When the bronze green cards are moistened with a piece of damp cotton wool, and applied to the lips or cheeks, the color assumes a beautiful rosy hue. Common sorts of rouge, called "theatre rouge," are made from the Brazil-wood lake; another kind is derived from the safflower (_Carthamus tinctorius_); from this plant also is made PINK SAUCERS.
