Siegfried's forge appears to be built of rocks, but really consists of an open framework covered with canvas. The top is masked in by painted work. On the top of the forge are two incandescent lamps, and at the front three more of these lamps have red globes and are on two circuits. They are lighted and dimmed as required for the effect on the artist-smith's face. Gas is supplied by two pipes, one jet is kept going constantly, lighting the large rose burner which gives the effect of the flame when the gas is turned on to it.
Steam furnishes the smoke and is turned on by a stage hand.
A shelf underneath the forge. When the heated sword is thrown into the trough steam is admitted to it by a stage hand, producing a very natural effect. It is the creation of Mr. Siedle, the property master, and is thirty feet long. The head is particularly terrible. The jaw, tongue and antennae are all movable.
