FOR PREPARING A BRILLIANT RED FIRE.
Weigh five ounces of dry nitrate of strontia, one ounce and a half of finely-powdered sulphur, five drams of chlorate of potash, and four drams of sulphuret of antimony. Powder the sulphuret of antimony and chlorate of potash separately in a mortar, and mix them on paper; after which add them to the other ingredients, previously powdered and mixed. For use, mix with a portion of the powder a small quantity of spirits of wine, in a tin pan resembling a cheese-toaster; light the mixture, and it will shed a rich crimson hue. When the fire burns dim and badly, a very small quantity of finely-powdered charcoal or lamp-black will revive it. This light is used in finale scenes, where the subject is heroic, national, or martial.
