The mode of preparation is the same as for solid paints, except that in order to give the rouge more consistency, less water and gum-tragacanth mucilage are to be used.
For moulding the rouge into sticks, round tin moulds about 2½ inches long and of the thickness of a finger are used. To facilitate the removal of the rouge sticks, the inside of the moulds is rubbed with a rag moistened with olive oil and wrapped around a thin stick of wood. After removing the sticks from the mould, they are allowed to dry superficially, and next wrapped first in tissue paper and then in tinfoil, one end, however, being left free from paper and tinfoil. They are finally labelled and packed in paste-board boxes.
White stick paint is prepared in the same manner as stick rouge, with the exception that the carmine is omitted.
Rouge en feuilles.—Prepared talc 1¾ ozs., carmine 2¾ drachms, olive oil 10 to 15 drops, spirits of sal ammoniac about 50 drops, pure alcohol 5¼ ozs., distilled water or rose water 8 ozs., gum-tragacanth mucilage 1¾ ozs.
The carmine is first rubbed fine, then the olive oil, spirits of sal ammoniac, and gum-tragacanth mucilage are successively thoroughly triturated with the carmine, next the talc is added, then the water, and finally the alcohol. Mix all intimately in a mortar with the pestle. The whole forms a fluid which, by means of a fine brush, is applied to a square piece of white card board, so that a circular disk the size of a silver dollar lies in the centre of the paper. The application of the rouge to the paper has to be repeated three or four times, allowing one layer to dry before applying the next. When the last layer is dry, the rouge is smoothed by laying a piece of tissue paper upon it and running the broad side of a paper cutter over the tissue paper. In packing, a piece of tissue is laid between the separate pieces.
Liquid Paints. Liquid paints are chiefly used by actors.
Liquid rouge.—Rose water 1½ quarts, carmine 1¾ ozs., Extrait rose No. 1, 1 lb.
Heat the rose water, without allowing it to boil, in a glazed earthenware vessel, add the carmine, previously rubbed fine, to the hot rose water, and stir the fluid with a clean wooden spatula until the carmine is completely divided. Then take the vessel from the fire and add a tablespoonful of spirits of sal ammoniac. The latter imparts to the rouge a brighter red, but not too much of it should be used, as otherwise the rouge acquires a bluish shade, and besides the odor of the spirits of sal ammoniac is not exactly agreeable. When the rouge is cold add 1 lb. of Extrait de rose, mix the whole intimately, and filter through white filtering paper into a clean glass bottle. The rouge has to be protected from sunlight.
White liquid paint.—Fine zinc-white 3 lbs., rose water or orange water 3½ quarts.
