In general, the basic materials you need (for example, those needed to create your first fountain) are readily available either as fertilizers, scrap, or at art suppliers. Storing such materials by nature is legal (there is no law preventing you from storing few kilos of fertilizers). However, when mixing those with the intent to create an explosive composition (and fireworks are small explosions controlled and designed by their makers), you move into the next category, which bring onto you the attention of the law.
The UK law allows the mixing of small quantity of pyrotechnic composition for the purpose of experiment. The law does not define how small is ?small quantity? but probably a few grams of low-level compositions are allowed.
Also, building fireworks (referred to as fusing and putting into practical use) are NOT allowed. Again, there is no clear definition of what is ?putting into practical use? means. Assumingly - if you do it in private to satisfy your own curiosity, that?s okay, but if you plan on showing it or selling it ? that?s illegal.
Note that if you plan storing compositions for the long run, or in large quantities, you need to register with the police and other institutions. You should read the documents recently added to the site and read the forums.
As for Ball Mill ? again, not illegal. Artists who deal with ceramics or prepare pigments from metal powder might have one in store. It is very easy to build one ? and you should look into that.
Overall ? my suggestion is that you mix only what you need, experiment far from any danger (Don?t try your new 8inch shell next to your neighbours windows - actually ? you should not try 8inch shell for the first couple of years?) and see if you like it.
If yes, you can investigate with the local authorities how to become legal.
Please note ? if this is the first time you look at pyrotechnic ? get some basic books. People on the forum will be glad to help with a good list. DON?T TRY ANYTHING until you sure you understood any term being used. Don?t be afraid to ask. Those who deal with fire are bound to get burned ? so you should do anything you can to minimize any dangerous to your personal safety and the safety of those around you.

To start you will need to learn more about the first three basic chemicals. Sulphur, Potassium Nitrate and Charcoal. They also happen to be what you make BP from.
Go to rec.pyrotechnic and search for "making airfloat charcoal". That's your first project...

I cannot be held responsible for the domestic strife that may come about from using the oven.
I hope this is of some use to you.

Though willow charcoal is popular, maple seems to hold some merit as well. Depends upon what your after. Certain species/varieties have particular qualities. Some are good for bp and others are good for the production of charcoal spark effects in comets and stars. Sometimes subtle and at other times very significant.
Historically, the availability of wood fibers has had a lot to do with things of this nature. Charcoal is the great big variable in the black powder ratios. The Japanese use paulownia(royal?) and hemp, pine and so on. I have myself grown paulownia just for hoots. Turns out that I negleted these gems and they have perished.
If you are very interested in the topic of charcoals I would recommend you pick up a copy of Pyrotechnica XVII. Not inexpensive if you compare it with pop. novels. Very comrehensive. It will save you countless hours of experimentation.
This of course is not to suggest that you break any laws. An educational read to be sure.

i have a pine tree right next to my house, i heard that the pine cones make good charcoal but thought it would be hard to work with(or maybe it was talking about the long,thin spikes). is it the pine wood or cones that i should use?
Posted 24 May 2003 - 10:53 AM
I can only imagine the article has used 'cuttings'. Pine cones of course contain seeds and if I recall they pop and such when baked. They make for a more interesting campfire. Especially while sipping whiskey out in the swamp in the fall during huntin' season.

a good conversion rate of wood to Charcoal would be 6 to 1, if you want to get hold of any British hardwood Charcoal powder please let me know, because the powder produced when making lumpwood Charcoal is considered a waste product.

Certainly you are correct when you say that not all is turned to ash if the hole is left open and oxygen is allowed back into said tin. The problem here is that if enough oxygen is supplied to an already warmish fuel© it is conceiveable that more than an excess of ash would be produced.
Concerning the pine issue......We ain't BBQing now are we:D
I would also take a stab at the chance that more nasties are produced by pine woods in the charcoal making process. Pitch helps to start campfires out in the swamp.
smpip...can you give me some specs on that hardwood C? A rich man I am not. However, I find purchasing C to be a bargain compared w/ manufacturing the stuff.

Once cooled the Charcoal is griddled and guided into bags, the Charcoal dust/powder is simply allowed to fall through to the ground, if I was to offer to purchase the powder (bagged of course),
there would be no problem in supply being outstripped by demand, because the producers would be making a bee line to my door.
The hardwoods used would range from anything from Beech to Willow, no Yew is ever used, (if you require more indepth info on hardwood types used, you only need to ask), if there was a demand for production of Charcoal using only one type of hardwood I am sure this could also be arranged.
Some years ago B&Q entered into an agreement to supply the public with locally produced British hardwood Charcoal (from managed woodlands), the characteristic's of British charcoal (when used on a BBQ) are quite unique, it will light with only a scrunched up piece of newspaper under it and it burns evenly.
I have not experimented with other Charcoal types within my mixes so I cannot comment on their pro's & con's, however since joining this forum I will start to.
Buying rather than producing is always going to be the best option, but it doesn't
hurt to know how.

All this talk of charcoal has motivated me to find some pine and give that a try in the near future. I'm not after speed as much as I am spark production. I need to conclude a few things I'm fiddling around with but if it turns out that pine has the qualities I think it does I will post any useful information. I imagine that it possibly would depend upon what time of the year you cut your wood. We will see now won't we.
