Behind the Scenes of an Opera-House, by Gustav KobbÃ©.
Two light-properties in “Faust”â€”the fire-cup and the spark-emitting sword of Mephistophelesâ€”are worth describing. The fire-cup is a goblet in the bottom of which are chlorate of potash, red fire, and sugar. Above these is suspended a thimble three-quarters filled with sulphuric acid and so delicately balanced that a slight movement causes the acid to drip on the powders and to ignite them, the fumes of the sugar leaving an agreeable taste upon the lips of the singer.
The method of causing the sparks to fly from the sword is as follows: Two wire-gauze plates connected with electric wires are placed upon the stage at the points where Mephistopheles and Valentine are to stand. A metal socket is sunk into the heel of the right buskin of each of the singers, and a wire of the same color as their costumes is attached to each socket, wound around the leg and passed through the belt. Standing upon the gauze plates they, as they draw their swords, slip the ends of the wires into the hilts and, when the swords touch electrical connection is made.
The flash of Wotan’s spear when Siegfried cuts it through with one stroke of his sword is produced by an explosion of gun-cotton in the spear and ignited by electricity, the electric wire passing through the weapon.
