Melt these together. When the metal has cooled, a piece the size of a silver quarter can be melted and taken into the mouth and held there until it hardens. This alloy will melt in boiling water. Robert-Houdin calls it Arcet's metal, but I cannot find the name elsewhere.
The eating of burning brimstone is an entirely fake performance. A number of small pieces of brimstone are shown, and then wrapped in cotton which has been saturated with a half-and-half mixture of kerosene and gasoline, the surplus oil having been squeezed out so there shall be NO DRIP. When these are lighted they may be held in the palm of any hand which has been anointed with one of the fire mixtures described in this chapter. Then throw back the head, place the burning ball in the mouth, and a freshly extinguished candle can be lighted from the flame. Close the lips firmly, which will extinguish the flame, then chew and pretend to swallow the brimstone, which can afterwards be removed under cover of a handkerchief.
Observe that the brimstone has not been burned at all, and that the cotton protects the teeth. To add to the effect, a small piece of brimstone may be dropped into the furnace, a very small piece will suffice to convince all that it is the genuine article that is being eaten.
To cause the face to appear in a mass of flame make use of the following: mix together thoroughly petroleum, lard, mutton tallow and quick lime. Distill this over a charcoal fire, and the liquid which results can be burned on the face without harm.[2]
To set paper on fire by blowing upon it, small pieces of wet phosphorus are taken into the mouth, and a sheet of tissue paper is held about a foot from the lips. While the paper is being blown upon the phosphorus is ejected on it, although this passes unnoticed by the spectators, and as soon as the continued blowing has dried the phosphorus it will ignite the paper.
Drinking boiling liquor is accomplished by using a cup with a false bottom, under which the liquor is retained.
A solution of spermaceti in sulphuric ether tinged with alkanet root, which solidifies at 50 degrees F., and melts and boils with the heat of the hand, is described in Beckmann's History of Inventions, Vol. II., page 121.
Dennison's No. 2 sealing wax may be melted in the flame of a candle and, while still blazing, dropped upon the tongue without causing a burn, as the moisture of the tongue instantly cools it. Care must be used, however, that none touches the hands or lips. It can be chewed, and apparently swallowed, but removed in the handkerchief while wiping the lips.
The above is the method practiced by all the Fire-Eaters, and absolutely no preparation is necessary except that the tongue must be well moistened with saliva.
Barnello once said, "A person wishing to become a Fire-Eater must make up his or her mind to suffer a little at first from burns, as there is no one who works at the business but that gets burns either from carelessness or from accident."
