Over the last few months, I've been putting together a document which covers in pretty extensive detail the answer to a question I get a lot. How do you go about doing pyrotechnics with only OTC chemicals?
My personal pyro interest (Aside from the more common things) is based mainly in the production of complex pyrotechnic devices with chemicals purchased and synthesized from only 'over the counter' sources such as agriculture suppliers, supermarkets and hardware stores. Since there isn't any definitive guide on how to do this, over time, to some extent, I've written my own. Below is attached this document.
It details the compositions I use and the sourcing/ synthesis I use to acquire each of the chemicals listed in the compositions on the first few pages.
Although I certainly don't expect anyone to read the whole thing some specific sections may be useful to those who have similar limiting factors to myself (mainly lack of suppliers) or who simply prefer to take a more hands-on approach to produce the chemicals we often take for granted.
It gets a bit chemistry based in sections but anyone with enough time should be able to get around it ok. Certainly, it's not too complex.
To help those looking for a specific piece of information, some notable articles contained include: Sourcing/ Finding Potassium Nitrate (KNO3), Sourcing/ Finding Lump Charcoal for Black Powder, Sourcing/ Finding Potassium Chloride (KCl), Sourcing/ Finding PVC powder (For Injection Moulding), Preparation/ Synthesis of Barium Chlorate (Ba(ClO3)2) via electrolysis, and Preparation/ Synthesis of Copper Oxychloride (Cu2(OH)3Cl)
In the next few months, I may post an updated version of this guide as I write more of it, but for now, I think it's complete enough to be of use. Further, when NYE rolls around I may get some video of all the compositions together firing in a series of mines and upload that so that each compositions performance can be seen.
