Prelude: This guide is by UK-SWAT of tM. This is the introduction page of the pyrotechnics section of the Militant Hand Book- a project started by The-Militia. My intention is hopefully help you all, please read and post your thoughts and criticisms.

INTRODUCTION

What is Pyrotechnics

Pyrotechnics is the art of fire, it is using knowledge of chemistry, resistant materials/design and creativity in order to create effects using chemicals and other materials. The actually word Pyrotechnics does expand into several fields such as high explosives (HEs), fireworks and special effects (SPX). This guide shall teach you about the firework field of pyrotechnics in order to give you a footing into the pyro world.

So who are you?

I am UK-SWAT, I have learnt from various sources and have been to many sites mostly teaching myself about pyrotechnics. As of this date (26th May 2007), I have just over 2 years of intense learning about pyrotechnics. To put it simply for you- the time for you to learn to create basic devices such as rockets (motors) and firecrackers (salutes) will be much quicker, providing that you read this well and also because I will be giving a list of sources to you.

As you can see I reside in the United Kingdom- does that mean that it is super hard for me to be supplied? No, the UK is one of the best places for basic pyrotechnics, I personally plan to move to America to eventually become a special effects technician or a pyrotechnician, that is my goal. Personally you shouldn't try to aim for my goals, pick your own targets. Most pyros do this as a hobby.

How will you teach me?

There is no such thing as a definite list of facts and figures that you must learn in order to practise pyrotechnics. Writing a list like that would be difficult and most likely have mistakes in it, the best way for me to teach you would be simply to give you a set of projects which in them selves have deliberately incorporated skills into them. For example, a project on making a basic rocket propellant (RP propellant) will teach you several skills: calculating ratios, how to mix chemicals safely, how to slowly wet chemicals and how to granulate and dry chemicals.

This is no straight forward 1+1=2 style of learning, it will gradually teach you and make you aware of the world of pyrotechnics. For example, there will be a term system in this book, this means that special pyro terms are highlighted, and you should learn to use them. These will be highlighted like this: Pyroterm. One particular example is the word: Firecracker. Use that word around your friends if you wish but the appropriate term is Salute. I shall no longer use the word firecracker in this guide in order to teach you not to use it.

Can't you just teach me to make a quick bomb out of house hold materials?

No, you can fill a film canister with match-heads but that is boring and as far as I'm concerned does not count as true pyrotechnics. You will however after a month of learning be able to produce decent salutes and rockets. They are more fun than "match-head bombs".

I wanna get some revenge though, I'm just gonna skim through your book to find the best way

If you want to do that, then you are on a sure fire way to kill yourself, pyrotechnics when done properly is for effect and fun. Not for carnage and revenge. It's acceptable if you wish to have a little late night fun whilst launching fireworks where they are designed to be (in the air), but that comes once you are fully confident with the device you are using. [Device: Any pyrotechnical finished item, for example rockets, salutes, smoke bombs etc.].

Ok, so what IS the point in reading this if you wont teach me to make a quick bomb?

There isn't, however you may still want to read this if you want to learn pyrotechnics. It only takes you one successful device for you to get hooked onto pyrotechnics, trust me. Making a bottle rocket fly high and fast gives a much greater satisfaction than watching a match-head bomb go off.

So erm... what is this match-head bomb you keep talking about?

Match head bomb is the term I use to describe any "salute" made using match heads, sparklers or those snapping caps. Sometimes I will refer to them as "kewl-bombs". A kewl is a person who thinks he knows about pyrotechnics when in reality he just plays with match-heads. He has most likely read the anarchist cookbook.

Anarchist cookbook?

Basically a kewl book that teaches you to make "cheap bombs", the badly written and unsafe information in that book will most likely get you killed rather than teach you to make "cheap bombs". Half the shit in the book doesn't actually work. You can find loads of fake versions of the AC (anarchist's cookbook) on the Internet but the genuine version if hard to find, don't bother reading that book. The amount of misleading crap in the book is surprising.

Well that was a mouthful, so I think that I am ready to start doing pyrotechnics, what's the first thing I should do?

If you haven't already, read all of the introduction rather than skipping down to here, it's for your own benefit, trust me.

Anyway, starting on pyrotechnics will take you a good month before you have the tools, knowledge and supplies to do something decent. Now there are things you can do to help you get started, collecting! Literally collecting items will help you in pyrotechnics greatly, rather than collecting random crap that you think will be useful, just refer to my list of things to collect:

- Plastic mallets and light hammers
- Drill bits and drills
- Electric motors
- Spoons, dowels and other things for mixing
- Metal rod and hollow rods
- Cotton string
- Things to store tools and chemicals in
- Ziplock bags
- Plastic and thick cardboard tubes
- A glue gun
- Craft paper
- Plastic storage containers.
- Lighters/sources of ignition
- Sieves and old strainers
- Meshes
- Icecream tubs and other stackable tubs

Most importantly.... Money!

Print this list or memorise it, just start collecting!

Now there are a couple things you wont find lying around your house, because pyrotechnics is a niche hobby it means that you wont find half the things you need on sale at Tesco/Walmart. So it means that you will have to look into a serious investment for pyrotechnics. Here is a list of the most important items:

Scales

Seriously, this should be the first thing you EVER buy. Scales are the most important tools in pyrotechnics because they are used to measure out the chemicals in a composition accurately so that it burns correctly.[Composition: A mixture of chemicals that can be dry mixed or binded together] You cannot measure things by volume or by eye. For example, adding too much charcoal to BP will cause the burn rate to drop significantly, bad enough that you pretty much cannot use it. Scales are essential, there is no two ways about it.

Any old postal/kitchen scale wont do, you MUST have scales that measure in 0.1g increments. That means that it should be able to measure something like 23.6 grams, it is essential to invest in a good set of scales that should last you sometime. Now I've seen ridiculous prices for precision scales on the internet, up to their thousands! That isnt nessasary, a good 20 american dollars or 10 british pounds will get you a good set of scales, from my favourite place. Ebay.

Search "0.1g scales" on ebay, here is a picture of my scales, small but reliable. You should aim for a scale like this:

http://i11.tinypic.com/4lqq0c8.jpg

Good set of scales, always use them, INVEST IN ONE, ITS MANDATORY! Bare in mind that cakecups actually weigh 0.2-0.4g, its just that I set my scale to ignore the weight of it. Buy a model that will measure up to at least 150g.

[b]Protection

When working in pyrotechnics the most important factor you must consider is safety, you must always be asking yourself whether what you are making will ignite in your face and if so what will happen. In order to make such judgements you need to have the right protection for individual tasks. During this book I will point out obvious mistakes to avoid but there are a few things that you need have handy.

When working with most powders you need to be aware that they can be so fine that they can float, especially chemicals such as high mesh aluminium or charcoal. You need to have a dust mask on for most tasks. Now dust masks can be simple cheap paper ones that you get from the builders discount or they can be more expensive ones that you can use for handling solvents. That doesn't mean you have to be as extravagant as this guy:

http://i206.photobucket.com/albums/bb185/UK-SWAT/smoothe.jpg

But anyway a standard dust mask like this is suitable for most applications:

http://i206.photobucket.com/albums/bb185/UK-SWAT/dustmask.jpg

Whilst saving your lungs is all fine and helpful unfortunately it isn't the only piece of safety essential, you need a good pair of flame retardant gloves. Heavy duty builders gloves and good quality paintball gloves serves the purpose pretty well. Whilst I personally hate wearing such constricting items such as most safety gear I also know what happens to people who don't. I'll make this short and sharp, don't wear safety gear? You risk this:

http://i206.photobucket.com/albums/bb185/UK-SWAT/rocketburn.jpg

He decided he was too "manly" to wear proper safety gear and a rocket he was making ignited and burned his hand pretty bad. Not only can he not use that hand for a good while but can you imagine the excruciating pain that not wearing basic safety gear can cause? If you still wish not to wear appropriate gear, then close this book and give up on pyrotechnics. Safety is mandatory. Even I have had a device light too quickly, I was testing a small batch of BP and the fuse failed. This meant that the fuse burnt way too fast, if it wasn't for my paintball gloves my finger tips would be looking more like cigarette butts right now.

Whilst these are the two main pieces of safety equipment that you must have there are a few additions that will be needed for different projects. Along with these protective items there is also the obvious rule about wearing old clothes, seriously. I decided to pump some stars whilst wearing my good hoodie and I got it covered in aluminium dust.[Pump some stars: The easiest process used to create cylindrical shaped stars, stars are small pieces of composition that burn brightly when lit and are used in a lot of amateur fireworks].

Grinding

Now, this is an important subject in pyrotechnics. In order for things to work, the particles must be of a certain size, if you paid attention in science class you would realise that the smaller particles are, the faster they burn. In terms of pyrotechnics that rule is true but can alter slightly, it will be explained when necessary. So in order to grind down chemicals to be appropriate particle sizes you need the right equipment. Please note what chemicals have been in what grinding apparatus in order to minimize accidents and contamination. [Contamination: foreign bodies or substances in a pure substance- like getting bits of charcoal in your sulphur]

For most chemicals that you want to quickly grind down you will use a standard mortar and pestle, they are available from most cooking stores and are cheap and effective ways to quickly pulverise things. My advice to you is not to go for traditional wooden mortar and pestles but to rely on ceramic and porcelain ones instead- this is because that wood scratches and dents easily and is hard to clean. For those who do not know what a mortar and pestle is here is a picture of a suitable one for pyrotechnics:

http://i206.photobucket.com/albums/bb185/UK-SWAT/mortar.jpg

Now after a while I got pretty tired of crushing things by hand, it was tedious and took a good 30 mins of work to produce something half decent so I upgraded to the next best thing, coffee grinder. This automated grinding machine will pulverise what ever you need within a few seconds, I use it for almost every safe chemical and it makes green mix real fast.[Green Mix: The very first stage of producing black powder, its just the right chemicals thoroughly mixed together] You can pick up a cheap new coffee grinder from guess where? Ebay! Should be priced from ?12-?16 or $22-$30. I got mine for ?12, here is a picture of it:

http://i206.photobucket.com/albums/bb185/UK-SWAT/coffeegrinder.jpg

Before someone does something stupid please note that this is an electric coffee grinder. Manual grinders are just a waste of money.

Fuse

Fuse, it is important to find a stable supply of fuse because of the importance that it serves in pyrotechnics. Fuse in general is used for everything from testing small batches of composition to being the fuse that links up your cake.[Cake:Several starguns linked together, star gun, a tube that launches a burning star high into the nights sky]Now there are many sources for fuse that you can attain, "rip em out of a few bottle rockets" is a stupid idea, you need to buy commercial fuse either from a pyro dealer or firework shop. There are many types of fuse ranging from Papermatch to Fast Yellow Visco. There is a few fuses that are the best all rounders and can be bought quite easily from multiple sources. My personal favourite UK source is www.ukvisco.com (http://anonym.to/?http://www.ukvisco.com). There are different categories of fuse, here are what they are:

Standard: These are just standard fuses that are used for any use, you will need to buy this

Effects: Special types of fuse which create effects from flying to crackling

Timing: These types of fuse are used for specific timing, such as for lighting several devices at once or for timing a shell to burst in the sky at its highest point (apogee).

We shall be using standard fuse, now here are the most suitible types of fuse that I would personally recommend. You mustbuy at least one of these types of fuse.

Chinese Fuse

Hot burning, leaves no trace and it lights most things, not only that but it also lights incredibly easily, this a good fuse for new people and its loads of fun lighting this off, why? It flies! Light a piece around 4cm long at it will fly. It is good for most things, the difference between 1/8" and 1/16" is the size of the fuse. I could go on for ever about fuse but there are certain things that you should learn by yourself. It burns at 1cm per second ( 98 second per metre is the actual burn rate). The difference between the two fuses are obvious, the size difference. Not only that but the fuses also vary in reliability, the thicker variety being the more suitible, however the size does mean that it will not fit in smaller holes.

American Fuse


This is a standard VERY hot burning fuse and will leave you a severe burn if you hold onto it, this seriously is a good fuse, but I wouldn't recommend it for new people. I have this fuse because I am more experienced with using fuse than before. I have come to the realisation that this is better than Chinese fuse. It has a thick nitrocellulose outer coating making it very reliable, according to the manufacturer it can be dowsed in water for an hour and still work fine. It burns at a steady rate of 1 cm per second ( 98 second per metre is the actual burn rate). Once you have tried Chinese I recommend this fuse. There is no difference in the properties of the fuse in terms of colour except for varying degrees of side spit. A little story: I was testing a star composition and used this fuse, I dropped the fuse a puddle by accident. So I picked it up, wiped it and used it with no problems.

Thanks to UK visco for the pictures.

Now those are the few essentials that are required to get into the world of pyrotechnics, if you have not obtained these items/tools then I still suggest you read ahead. Not only will this give you a major advantage when it comes to actually doing the projects but it is also good to read ahead. At this point I shouldn't expect you to be fully prepared for a good 2-3 weeks, if not longer. To keep you busy whilst you gather the essentials here is a link to a good site that explains a lot of pyro projects:

www.pyroguide.com

It is an ok site to me, this is because once you learn more about pyrotechnics you will eventually discover how low detail the projects are and will progress without it. So what now you may ask. Well, its time to move onto the projects section!

How the hell did I not notice this thread before? I was actually contemplating making something similar but this is so well-done I don't think there's any need for me to bother!

Maplex, this ought to be right up your street. Pay attention to the pic of the burnt hand!! Even a couple of grains of black powder burning somewhere you'd rather they didn't can hurt like hell.

i read through the entire guide twice, copied it into word, and saved it.

I have the saftey gear, scale, and mortar and pestle.

Just need to get fuse now, and as you said on another thread i can order it online when i get a prepay card, hopefully soon.

And JT, unless th0r or someone has the other parts of this guide somewhere, you could always do the projects section.

I might well do. There's loads of fairly basic and more-or-less legal stuff that can be made with minimal risk of blowing the shit out of yourself. Once I get paid enough to get some supplies in I will certainly contribute. I'd prefer to wait until I can supply pics and vids and stuff too. It's nice to have some visual "proof of concept" so you can see what something's supposed to do.

Definetly.
If you need any help with the pics or vids or anything i would be glad to help, since i can easily steal chemicals and other supplies from my school.

For UK members, I found the site hobbychemicals.co.uk recently. They seem to stock all the useful, legal "hobbyist" stuff without the nasty chemicals. I plan on getting my bits from there so I will hopefully be able to vouch for them once my order arrives safe and sound.
