- Incendiaries are used to destroy all types of flammable substances. In add-
- ition incendiaries can be used to destroy metal structures or used on living
- targets as in the case of flame throwers.
- Incendiaries can be broken down into a few groups. These are petroleum based,
- metal alloys, thermites, metal-salt mixes, and exotics. The choice of
- incendiary depends on the target to be destroyed.
- The petroleum based incendiaries like napalm, use the oxygen from the air to
- keep combustion going. If the fire is smothered it will be extiguished.
- The petroleum can thickened (like napalm) or it can be a heavy oil (hard to
- ignite). Lighter types of petroleum (ligroin) are not the best to use as they
- evaporate quickly and the fumes tend to flash or explode instead of burning
- for a sustained time. Petroleum liquids burn at about 1000 deg. C. and
- release as much as 6 kcal/gm. They are usually used against wooden structures
- and other easily flammable things like people.
- Metal alloys such as magnesium alloys also use oxygen from the air to support
- combustion. In addition they can also use nitrogen from the air and still
- burn. If they are smothered they can reduce the smothering agent and still
- burn. A large amount of water or foam are best for fighting a magnesium
- fire. A small amount of water can give up its oxygen to the magnesium and
- release hydrogen gas. The result is a pretty good explosion. A magnesium
- alloy called "electron" was used during the second world war. This was made
- of about 90% magnesium, 8% aluminum, and the rest zinc and manganese. This
- alloy was strong and produced 2000 deg. C. and about 6 kcal per gram.
- This was used against wood or metal structures.
- Thermites are mixtures of an active metal and a less reactive metal oxide.
- The active metal reduces the less active metal oxide pulling off the oxygen
- and releasing a lot of heat and molten metal and metal oxide slag.
- Thermites are usually used to attack metal targets and are very effective in
- this role. A two or three pound charge can be placed on the hood of a auto
- and ignited. The thermite will burn through the hood and drip molten metal
- onto the engine. While this won't melt the engine it will warp or crack it
- plus it may sever gas lines which will start a secondary fire. Thermite
- formulas a varied but the standard mix is 25% aluminum powder, 75% iron scale
- (iron oxide). Thermites burn at about 2500 deg. C. Thermite is used almost
- exclusively against metal to weld it or melt it.
- Metal - Salt mixtures use a combustible metal and a salt oxidizer. They
- cannot be smothered or extinguished easily. To fight these fires the best
- tactic is to cover the device with sand or shoot them with a water jet. The
- jet will help break up the incendiary and wet any mixture that has not burnt.
- These mixtures are composed of oxidizers like potassium nitrate, metals like
- aluminum or magnesium, and fuels like sulfur, charcoal, or oils.
- These formulas produce a flame when burning unlike thermite and burn very
- quickly when compared with thermite. These mixes can be used in small caliber
- projectiles to make an incendiary shell. Usually the shock of the shell hit-
- ting the target sets off the incendiary. They burn at about 2000-3000 deg. C.
- Metal - Salt mixtures are usually used against easily flammable objects.
- Exotic incendiaries exist that ignite on exposure to air, release poisonous
- gases, or produce a second incendiary chemical. These incendiaries are used
- for special circumstances and targets.

- A Short Study of Arson
-
- An understanding of fires should be acquired if you want to use them to your
- best advantage. A study of the target should be made if possible. Find out
- what materials from the target can be used to start the fire. How long will
- it take the fire fighters to arrive? If the target is a building is there a
- sprinkler system installed? Fire and smoke alarms? Is the building wood
- framed or steel? A steel frame building can be destroyed if the temperature
- of the steel reaches 1000 deg. F. for 10 mins. This destroys the temper of
- the steel. Are the walls hollow? This can spread the fire from the bottom to
- the top of a two story house in about 1 min. A fire can be started in a
- corner of a room. This uses the walls to reflect heat into the room and also
- provides two walls for fuel. Use whatever materials are handy to help feed
- the fire. Make a trip to the library and look for books on fire fighting
- techniques and materials. Study these and learn what the fire fighters will
- use to stop your efforts. You can study chemical hazard lists to find incom-
- patible materials that can make an explosion or fire when combined. If a fire
- is started with good planning it makes little difference if its set with a
- book of matches and a cigarette fuse or an incendiary using high tech bells
- and whistles. An incendiary is more effective than an explosive in destroying
- some targets. Once an explosive goes off the damage is done but a fire builds
- until all the fuel is consumed.
- Here are a few characteristics of common flammable substances:
-
- Wood: Wood contains about 15-35% moisture. The less moisture the easier to
- ignite. At 110deg. C. wood dries, gases start liberating. 150deg. C. wood
- gives off more of these flammable gases. 230deg. C. wood begins to char. 300
- deg. C. carbonization of the wood. Above 300deg. C wood begins to burn.
- Wood is a good insulator and can keep fire from spreading easily if it blocks
- radiant heat. Green wood ignites with difficulty.
- Paper: Paper along with grain products (hay and cereal grasses) ignite very
- easily if dry. If the paper is bundled up however, you will find it is hard
- to ignite.
- Petroleum products: The flammability of petroleum liquids are determined by
- their flashpoint. The lower the flashpoint the easier the liquid is to
- ignite. Those liquids with higher flashpoints may have to be heated before
- they are flammable.
- The minimum concentration of vapors to be flammable for common substances are
- ethyl alcohol-73, acetone-65, benzene-49, ethyl ether-39, gasoline-33 MG/L.
- At 0 deg. C. ethyl alcohol gives a concentration of 34 mg/l and is not
- flammable at that temperature. In contrast ethyl ether has a concentration of
- 780 mg/l at 0 deg. C. and is flammable.
- If you are trying to hide the fact that arson is the cause of the fire, try
- to use what is already on scene at the target. An electrical fire can be made
- by using a razor blade to slice into the insulation of a wire. If the wire is
- the stranded type pull out about 2/3 of the strands and cut them. A fire will
- start in that section of wire. If the wire is the solid type, file a section
- of wire to make it thinner. Arson investigators look for a hot spot in the
- ruins to find where the fire started. This hot spot is usually a section of
- target that is very charred. They especially examine the floor to see if it
- is charred. They look for char trails to see if the fire has been led to
- different sections of the target. A very fast spreading fire will be invest-
- igated as an arson job. They also use sniffers and gas chromotagraphy to look
- for traces of gasoline and other accelerators. An arsonist has to be on his
- toes to fool the investigators.
-
- Incendiary Devices and Formulas
-
- Incendiary Capsule: This device uses a pemanganate/glycerin reaction to make
- a short delay fire. Obtain a large gelatin capsule. Fill the larger side with
- potassium permanganate. Flatten a piece of plasticine to about 1/16" thick
- and press it over the permanganate to seal it into the capsule. Peel away
- the excess plasticine so the chemical is sealed in the capsule by a small
- disk of the putty. Fill the other side of the capsule about 1/2 full of
- glycerin. Take a small splinter of wood (toothpick) and place it in the
- glycerin. Now assemble the capsule but be careful not to press the ends of
- the capsule together very much. When you wish to use the capsule, simply
- press the ends of the capsule together. The splinter pierces the plasticine
- which allows the glycerin to contact the permanganate. The reaction starts
- a short time later and will ignite such things as paper or wood shavings.
- These devices cannot take much rough handling and usually have to be made
- near where they must be used.
-
- Spontaneous Combustion: Most people may have heard that you are not supposed
- to put oily rags in the garbage until they dry out because they may start
- a fire. This is because when oil drys it oxidizes and gives off a good deal
- of heat. This heat can build up in a closed container and ignite the rags.
- If you want to cause spontaneous combustion on purpose it is necessary to
- obtain oil dryers as these cause the oil to oxidize. Check out paint
- shops and see what they have to offer. You may wish to try drying oil which
- is a preparation of oil with premixed dryers.
- Dampen cotton, rags, wood pulp or the like with the oil and dryers. The
- combustible should not be dripping with the oil but it should be moist
- throughout. Make a 1" hole in the bottom of a styrofoam coffee cup and a 1"
- hole in the lid of the cup. Pack the cup with the oily combustible but leave
- a hole going through to the bottom hole. Do not pack the combustible too
- tightly in the cup. Put the lid on and lay the cup down on its side Or put
- the cup on something so that free air can reach the hole in the bottom of
- the cup. In as little as 1/2 hr. to as much as 4 hrs. later the cup will
- burst into flames if the oil is reactive enough. The time delay will depend
- on such things as ambient temperature or air movements.
-
- Phosphorous Delay: White phosphorous is a substance that ignites on exposure
- to air. You can dissolve it in carbon disulfide which gives you a liquid
- that can be poured on to paper or the like. As the disulfide evaporates, it
- leaves behind particles of phosphorous which will ignite the disulfide fumes
- and the paper. Since the disulfide evaporates fast you can add benzene or
- naptha to it to keep the evaporation down. One drawback to using this mix is
- the disulfide smells like sulfur which can give away its presence. Both the
- phosphorous and the carbon disulfide are extremely dangerous to handle. They
- should only be used after you are familiar with them. As a note, carbon
- disulfide fumes can be ignited by the heat of a 60 watt lightbulb. Handle
- with care.
- About a century ago, white phophorous (WP) was added to a glue called Chloral
- Du Pottage. This was a glue made from chloral hydrate. The resulting mixture
- was used to soak a piece of paper that was then placed into a glazed envelope
- and sealed. After the glue dries, if the envelope was opened it burst into
- a violent flame. These fire bombs remained active for about 24 hrs. after
- which the phosphorous was slowly oxidized and the bomb became inactive.
- The chloral glue formula may be found in an old library book called Richard's
- Book of Formulas (or something similar). Perhaps you can bring this device
- up to date by using an acrylic glue
-
- Fireflys: These are simple devices used to blow up a car. One consists of a
- large gelatin capsule that is half filled with calcium carbide while the
- other half contains a piece of sodium metal.(store these in a dry place,
- and not for very long ) 2 or 3 of these can be dropped into a automobile
- gasoline tank. Condensation causes water to form in the bottom of the
- tank. This water dissolves the gelatin which exposes the chemicals to the
- water. The carbide reacts with the water to form acetylene while the sodium
- starts a fire. The resulting explosion ruptures the gas tank and ignites the
- gasoline. Another form of firefly is made of a small cork float. This is
- weighted to keep one end up when floating. On this exposed end a small spiral
- of platinum wire is fixed. A small amount of cotton is placed inside the
- spiral. To use these, soak the cotton with gasoline just before dropping one
- in a gas tank. As the gas tank empties, air replaces the gas used. The air
- and gasoline fumes reach a level that causes the platinum to behave as a
- catalyst which ignites the air/gasoline mix. In trial, the platinum firefly
- has 50/50 success rate. Removing the cotton may increase the probability of
- an explosion at the risk of some danger when dropping the device into the
- tank.
- Note: Some gas tanks have a screen in the gasoline tank so you cannot drop
- anything into the tank until it is pierced. Also when using the sodium metal/
- carbide firefly you may want to pour about 8 oz. of water into the tank after
- putting in the capsules. Instead of platinum wire, you may want to try using
- the element from a catalytic hand warmer. These are the hand warmers fueled
- with a lighter fluid type fuel. Also keep in mind that this device usually
- works as the car is being driven which will probably result in death. If you
- don't wish to kill someone, just use an icepick and poke a hole in the gas
- tank to empty it.
-
- Sodium Peroxide: This is a chemical that releases oxygen and heat on contact
- with water. A small amount of this chemical can be sprinkled on rags or paper
- which will ignite after a time if the humidity is high enough. Mixtures of
- this chemical and powdered metal should be avoided as spontaneous ignition
- may occur during mixing.
-
- Sausages: These where airdropped during the vietnam war. All they consist of
- is a liquid incendiary sealed into a heavy plastic bag. During the war a
- string of these were dropped from airplanes to ignite the target. The incen-
- diary used was Napalm B which is a plastic gel made by mixing polystyrene
- foam with gasoline. Sometimes sodium nitrate and sulfur was added to help
- the burning. A reasonable facsimile can be made up for the purpose of carry-
- ing a small incendiary device. The weight of the filling should be about 4oz.
- A standard blasting fuse can ignite these.
-
- Timed Gas Explosion: Obtain a butane lighter refill. These are the aluminum
- cylinders used to refill butane lighters. Use a paint remover on it to take
- off all of labeling. After the paint is removed, clean up the cylinder with
- some fine grit sandpaper. Now get a large glass jar. Bring these plus a
- bottle of sodium hydroxide (lye,drano) to your target. If the target has a
- gas water heater (or any appliance with a pilot light) this will be used to
- ignite the explosion. Otherwise you will need a candle (try a trick candle,
- one of the ones you can't blow out). Put the jar down next to the heater, and
- put the stripped cylinder in it. Fill up the jar with lye and leave quickly.
- The lye will eat the aluminum cylinder and release the gas in an explosion.
- the pilot light on the heater will ignite the butane and cause an explosion.
- This will take about 10 mins. depending on the strength of the lye. If you
- use a candle, set it away from the jar so when the gas first releases the
- flame does not blow out.
-
- Accelerant: As I said before, arson investigators will look for traces of an
- accelerant especially if the fire is fast spreading. The usual accelerant,
- gasoline, leaves traces that are easy to find. However, if you take sodium
- chlorate and dissolve about 150 gms. in 150 ml. of warm water you will make
- an accelerant that is hard to find. Soak the substance to be ignited with
- this liquid. When it dries the material will be highly flammable. Be careful
- as the material will be highly spark and friction sensitive. The chlorate,
- while not flammable in itself will give off oxygen when heated and make any
- organic material very flammable. When the material is burnt, the chlorate
- reduces to salt (NaCl, table salt). This is usually dissolved in the fire
- fighters water and is very rarely found, Even if it is found, They invest-
- igators will probably not make its connection to the fire. The chlorate
- treated material will also ignite if contact is made with sulfuric acid. This
- can be used to produce an acid-delay. Fill a rubber ballon with about an
- ounce of sulfuric acid and tie off the ballon. Place this ballon on the
- treated substance. When the acid eats through the ballon the material will
- ignite. Make sure the ballon has no holes in it.
-
- Napalm: Napalm is simply thickened gasoline. It burns longer than gasoline
- and is not as explosive as gas. A simple napalm is made by adding two con-
- centrated solutions together. One is a solution of soap (not detergent), the
- other solution is aluminum sulfate (alum). A precipitate results when the
- solutions are mixed. This precipitate is filtered out and dried. This powder
- is usually added to gasoline in about 5 - 15% strength. Another type of
- napalm is made by melting parafin wax and pouring it into gasoline. When the
- gas cools it will thicken up. A form of solid gasoline is made with polyvinyl
- alcohol and formaldehyde as the thickener.
- A thin napalm is used for flamethrowers. Another mix for flamethrowers is
- 25% kerosene, 50% heavy oil, and 25% gasoline. The fuel for flamethrowers
- should not burn up in the travel to the target but rather on the target.
-
- Goop: Goop is an attempt to get the best of napalm and metal incendiaries in
- one mixture. It is made in two parts.
- Part 1
- Magnesium Powder 40%
- Asphalt 20%
- Heavy Oil 20%
- Gasoline 20%
- Part 2
- Aluminum Powder 20%
- Iron oxide 40%
- Potassium Nitrate 30%
- Sulfur 10%
- This is mixed by taking 50% by volume of part 2 and mixing it well with part
- 1. This is easily ignited and produces a large flame plus a lot of heat. It
- cannot be extinguished by normal means and is effective on both wood and
- metal.
- In Afganistan, the Russians were reported to air drop an incendiary "goop"
- that was stable until disturbed (stepped on). Then the incendiary burst into
- flames. This is very likely a WP mixture along with oxidizers and a tar-like
- substance that also kept the WP and the oxidizers from reacting with each
- other. How it was kept stable in storage is unknown.
-
- Thermite: One of the best known incendiaries is thermite. The thermite reac-
- tion was used originally to produce super pure metals but was adapted to
- war uses. The most common formula for thermite is 25% coarse aluminum, 75%
- iron oxide. It is difficult to ignite but once burning it is almost imposs-
- ible to put out. For more information on thermite see my file Thermite.txt
- on the HOTLINE BBS.
-
- Thermite Incendiaries: These mixtures use additional chemicals that help
- thermite ignite easier, produce a flame, or increase the heat liberated
- by the thermite reaction. The thermite makes up 50% - 80% of the mixture.
-
- FORMULA 1
-
- Barium Nitrate 25%
- Iron Oxide 50%
- Aluminum 25%
-
- FORMULA 2
-
- Barium Nitrate 45%
- Iron Oxide 25%
- Aluminum 15%
- Magnesium 15%
-
-
- Metal - Salt: These mixtures are almost used exclusively to load a projectile
- to make it explode into a ball of flame and sparks upon impact. These are
- used against gas tanks and the like. They must be insensitive enough so the
- setback forces of firing the projectile does not ignite the incendiary. Yet
- they must be sensitive enough to ignite when they hit the target. Some
- typical mixtures are:
- FORMULA 1
-
- Potassium Perchlorate 50%
- Magnesium 25%
- Aluminum 25%
-
- FORMULA 2
-
- Potassium Nitrate 50%
- Potassium Perchlorate 15%
- Aluminum 25%
- Charcoal 10%
-
-
- The above two formulas are more suitable for incendiary projectiles. They
- explode more than burn and the flash from the explosion ignites the target.
- Metal-Salt mixtures that burn slower and are more suitable for an incendiary
- charge usually include oil or a wax plus sulfur to slow down the burning.
- The following formulas are examples.
-
- FORMULA 1
-
- Potassium Nitrate 60%
- Light Oil 20%
- Aluminum Powder 10%
- Sulfur 5%
- Charcoal 5%
-
- FORMULA 2
-
- Potassium Nitrate 55%
- Paraffin Wax 20%
- Iron Oxide 10%
- Aluminum Powder 10%
- Sulfur 5%
-
-
-
- Exotic Incendiaries: Some exotic incendiaries are pyrophoric metals, phoph-
- orous/sulfur mixtures, alkyl-alkali metal derivatives, and boron compounds.
- Since the use of these incendiaries require more knowledge than can be gained
- by simply reading a few pages on incendiaries, only a quick review will be
- given.
- Pyrophoric metals are metal powders that are barren of any oxide coating and
- are of such small dimensions that they catch fire on exposure to air. An
- example is made by heating lead tartate (made by adding tartaric acid to lead
- acetate) in a test tube. While you can still smell the tarlike fumes coming
- off, cork the tube. Throw the tube and break it or just open up the test tube
- and the lead will burst into sparks. Pyrophoric metals are made in an inert
- atmosphere to stop oxidation of the metal.
- Phosphorous/Sulfur mixtures form an alloy that is liquid at normal temper-
- atures. The usual percentages are 75% white phosphorous and 25% sulfur. This
- compound ignites spontaneously in the air and gives some nasty burns plus
- releases large amounts of noxious sulfur dioxide fumes when burning.
- Dimethyl sodium is a liquid that is also spontaneously ignites in the air.
- Alkyl metal derivatives are poisonous to handle
- Boron is a high energy metal. Compounds of boron release very great amounts
- of heat when burning. Unfortunately, these compounds are also very poisonous
- and this has limited research in their use.
-
-
- Before making incendiaries, find out the properties of the chemicals you are
- using. Be especially careful of white phosphorous. WP has the ability to
- literally burn its way through your body. To get it out of say your arm,
- turn your arm upside down so the WP burns back through the hole it made going
- in. The burns are very slow to heal and WP is poisonous and destroys the
- liver and bones.
- Safety equipment should be used when making these devices and mixtures.
- Invest in a good face shield, leather gloves and aprons will protect against
- flash burns. A leather skull cap will help protect your hair. These and
- other equipment may save you from injury or death. Remember, it is your
- responsibility if you try using any of this information.
