Amandine.

Almond Cream.—Melt ten pounds of purified lard in an enamelled iron pot or a porcelain vessel, and while increasing the temperature add little by little five pounds of potash lye of 25% strength, stirring all the time with a broad spatula. When fat and lye have become a uniform mass, 2¾ to 3½ ounces of alcohol is gradually added, whereby the mixture acquires a translucent, crystalline appearance. Before the alcohol is added three-fourths to one ounce of oil of bitter almond is dissolved in it. The soapy mass thus obtained is called “almond cream” (crême d’amandes) and may be used alone for washing. For making Amandine take of—

Expressed oil of almonds10 lb.
Almond cream3½ oz.
Oil of bergamot1 oz.
Oil of bitter almond1½ oz.
Oil of lemon150 grains.
Oil of clove150 grains.
Oil of mace150 grains.
Water1¾ oz.
Sugar3½ oz.

In the manufacture the following rules should be observed.

Effect the mixture in a cool room, the cellar in summer, a fireless room in winter. Mix the ingredients in a shallow, smooth vessel, best a large porcelain dish, using a very broad, flat stirrer with several holes. The sugar is first dissolved in the water and intimately mixed with the almond cream. The essential oils are dissolved in the almond oil contained in a vessel provided with a stop-cock. The oil is first allowed to run into the dish in a moderate stream under continual stirring. The mass soon grows more viscid, and toward the end of the operation the flow of oil must be carefully restricted so that the quantity admitted can be at once completely mixed with the contents of the dish. Well-made amandine must be rather consistent and white, and should not be translucent. If translucency or an oily appearance is observed during the mixture, the flow of oil must be at once checked or enough almond cream must be added to restore the white appearance, under active stirring.

As amandine is very liable to decompose, it must be immediately filled into the vessels in which it is to be kept, and the latter, closed air-tight, should be preserved in a cool place. By adding ¾ ounce of salicylic acid, amandine may be made quite permanent so that it can be kept unchanged even in a warm place.

We have described the preparation of amandine at greater length because its manufacture requires some technical skill and because the preparation of all other cold-creams corresponds in general with that of amandine.
