Illuminants

Recommended Posts

Hello there.

I am searching for blue, yellow and peech flare/illuminant/lance/torch compositions based on potassium chlorate (KClO3).

Ah come on... maybe you should use the search function?

It is one of the most wel known pyrotechnic pages on the web, so first look at sites like this one.

Well, I know the search function and google and this page, too.
I just want to get some good comps. and not that strange stuff.
Maybe you tried out something...

I suppose peech is meant to be peach, or some kind of red? A very good red can be made using the following composition:

66 Strontium Nitrate
25 Potassium Chlorate
09 Shellac

All oxidizers should be finely powdered like icing sugar, the shellac something like passing 120# or finer. It doesn't come very close.

Yellow can easily be made by taking potassium chlorate, a random fuel (a compatible one preferably) and a random sodium salt. Something like this should produce a bright yellow flame, but burns quite fast:

7 Potassium Chlorate
2 Red Gum
1 Sodium Bicarbonate

Some experimentation is needed to find a ratio matching your needs.

Blue is extremely hard to make without paris green and ammonium perchlorate. You might try a nitrocellulose or nitroguanidine based composition with some chlorine donor and copper salt (copper oxichloride perhaps?).

That`s what im talking about, thanks a lot!
Today I tried Weingarts "Toy Blue light" comp. but it was more a white than a blue colour.

The next try with

KClO3 65
CuCl (Copper(I)chloride) 20
SrCO3 5
Red Gum 10

worked much better!

Last week I made some bleu torches

I used my own composition.

KClO3...6
PVC......2
CuO......0,5
Dextrin..+0,5 (binder)

The ratio's where tested by just trying.
It burns pretty quick

My faforite yellow composition is:

KClO3....7
Dextrin...3
NaCl.......1
