The mode of working these lights is to place one of the powders, for which we shall presently give you prescriptions, in an iron shovel, and apply a lighted match. The powder will begin to burn slowly, emitting a bright red or green light, accompanied by volumes of smoke. Before exhibiting these lights, all others in the room, gas or lamps, should be turned down as low as possible.
If the operator stands behind the scenes, so as to be out of sight during the performance, the effect is what Artemus Ward would call Trooly Grand.
In order to procure the lights, go to some druggist and give him the following prescriptions. He will procure the necessary materials and mix them for you.
RED FIRE.
Forty parts of dry nitrate of strontian, thirteen parts of finely powdered sulphur, five parts of chlorate of potash, and four parts of sulphuret of antimony. The chlorate of potash and sulphuret of antimony should be powdered separately in a mortar, and then mixed together on paper; after which they may be added to the other ingredients, previously powdered and mixed.
GREEN FIRE.
Green fire, when burned in a reflector, sheds a beautiful light on all surrounding objects. Take of flour of sulphur thirteen parts, of nitrate of baryta seventy-seven, of oxymuriate of potassa five, of metallic arsenic two, of charcoal three. The nitrate of baryta should be well dried and powdered; it should then be mixed with the other ingredients, all finely pulverized, and the whole triturated until perfectly blended together. A little calamine may be occasionally added, in order to make the compound slower of combustion; and it is above all things requisite that the rubbing together of the materials should be continued until they are completely mixed.
It may so happen that in some of your parlor theatricals you may wish to introduce a storm, so we will tell you how to manage it.
There are several elements in a storm which can be counterfeited.
