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 chlorate of potash and the
sulphuret of antimony separately in a mortar, and mix them on paper;
after which, add them to the other ingredients, previously powdered
and mixed. No other kind of mixture than rubbing together on paper is
required. For use, mix with a portion of the powder a small quantity
of spirit 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.
