of the following oxidizing agents: sodium dichromate, potassium permanganate, potassium nitrate, or potassium dichromate (no coarser than granulated sugar).
    Container with tight-fitting lid.
    c. Preparation.
Using a clean, dry spoon, place one of the metal powders or filings in the container to one-third container volume. If metal filings are used, they should be free of grease.
Wipe the spoon with a clean, dry cloth and add an equal quantity of one of the above oxidizing agents.
Tighten the lid on the mixing container, turn the container on its side and slowly roll until the two powders are completely mixed. The mixture is now ready to use and may be stored for months in this tightly sealed container.
    d. Application.
To use this subigniter, spread the material to a depth of at least ¼ inch on the top surface of the thermite which is held in an assembly described under Application of Thermite Incendiary (0307). Spread another igniter, preferably Sugar-Chlorate (0201) on top of this subigniter to about the same depth. Prepare the mixture for ignition with Fuse Cord (0101) or Improvised String Fuse (0102) in the normal manner. The fuse cord should terminate near the center of the igniter mixture. The fuse cord initiates the sugar-chlorate igniter which ignites the thermite subigniter which then ignites the thermite.
For delay times longer than those conveniently obtained with fuse cord in ignition of thermite by this subigniter method, refer to chapter 5.
    Caution: Never attempt to ignite thermite subigniter without at least a few seconds delay fuse. It burns extremely fast and hot, and the user could be seriously burned if he were too close when ignition occurred.

CHAPTER 4
INCENDIARY MATERIALS
    0301. NAPALM
    a. Description.
This item consists of a liquid fuel which is gelled by the addition of soap powder or soap chips. It is easily prepared from readily available materials.
This incendiary can be directly initiated by a match flame. However, if delay is required, the incendiary can be reliably initiated by a delay system consisting of any igniter listed in chapter 3 coupled with a delay mechanisms found in chapter 5.
Napalm incendiary is easily ignited and long burning, and is suitable for setting fire to large wooden structures and other large combustible targets: It adheres to objects, even on vertical surfaces.
    b. Material and Equipment.
    Soap powder or chips (bar soap can be easily shaved or chipped). Detergents cannot be used.
    Any of the following liquid hydrocarbon fuels: gasoline, fuel oil, diesel oil, kerosene, turpentine, benzol or benzene, toloul or toluene.
    A double boiler made from any material with the upper pot having a capacity of at least two quarts.
    A spoon or stick for stirring.
    A source of heat such as a stove or hot plate.
    A knife or grater if only bar soap is available.
    An air-tight container.
    c Preparation.
Fill bottom of double boiler with water and heat until the water boils. Shut off source of heat.
Place upper pot on top of bottom pot and remove both containers to a point several feel from the heat source.
Pour soap chips or powder into the upper pot of the double boiler to one-quarter of pot volume.
Pour any one of the liquid hydrocarbon fuels listed under Material and Equipment above into the upper pot containing the soap chips or powder until the pot is one-half full.
    Caution : Keep these fuels away from open flames.
Stir the mixture with a stick or spoon until it thickens to a paste having the consistency of jam. Do this in a well ventilated room where the vapors will not concentrate and burn or explode from a flame or spark.
If the mixture has not thickened enough after about 15 minutes of stirring, remove the upper pot and put it several feet from the heat source. Again bring the water in the lower pot to a boil. Shut off heat source, place upper pot in lower pot at a location several feet from the heat source and repeat stirring until the napalm reaches the recommended
