One can carefully make chlorate and sulfur compositions, as long the sulfur and chlorate are quite pure, but there are some other chemicals that KClO3 should never be mixed with:
1. Copper chloride 2 - DEATH mix. Why? Because it is hygroscopic, very soluble and acidic in solution. It can also form copper chlorate (very unstable)
2. Copper sulfate - Death mix, for the same reason as copper chloride
3. Ammonium salts, especially ammonium perchlorate. Ammonium chloride can be an exception.
With modern chemicals, sulfur and chlorates mixes can be handled quite safely. As long there's no acidity in the sulfur and in the mix, such compositions do not pose the spontaneous combustion problem as in the past. Also, they have a good shelf life. Remember that safety match heads are made from KClO3, sulfur, stabilizer and binder.
In the past, volcanic, acidic sulfur was used and KClO3 made in a non electrolytic way. Because of this fact, many accidents have occured.
Potassium chlorate and sulfur compositions are very beautiful, because the sulfur burns with a very clean color. Modern compositions contain organic fuels that have carbon, and unburnt carbon washes the colors.
Another benefit from the sulfur, is that it makes the chlorate release its chlorine, giving extra chlorine to the mix, making better colors.
Such compositions should be made carefully only by advanced pyrotechnicians though.
It's the same meaning. Sulfur makes the chlorate release its chlorine by combining with the K+ cation, making the sulfide or even the sulfate in an oxygen richer environment.
spontaneous ignition means it ignites on its own, like when a hydroscopic chemical absorbs water from the air and causes a runaway reaction without help from anything else.
chlorate+sulphur does not do this, though it is often called a 'death mixture' though because of its extreme friction and shock sensitivity.
people should never play around with such formulas without extensive knowledge on the chemicals involved.
@BakerGod .......................... Finely powdered sulfur will react with the oxygen of the air, forming sulfur dioxide. Sulfur dioxide reacts further with moisture to form sulphurous acid, which eventually reacts with chlorate forming chloric acid. Chloric acid makes mixture unstable, and is even capable of igniting sulfur at room temperature
Look out for the potential risk of spontaneous ignition with sulfur and chlorates!! + That the mixture is extremely sensitive to shok and friction. For safer option, use PVC and or/and red gum or shellac as a feul. Or just perchlorate and sulfur offcoarse.
Oh and copper(II) salts (CuO for instance) can be used as well to act as a bleu flame "donor.
I've always wondered if there was a way you could have a bit of a chlorine donor CONTINUE to burn once the item had already burst with the remaining split-second flame, therfore making a blue flash.
Ammonium salts with KClO3 can form traces of NH4ClO3, very unstable explosive, which can spontaneously ignite the composition.
5. Red phosphorus - AKA armstrong's mix. Crazy sensitive composition, can ignite from friction even when wet.
6. Zirconium - very reactive metal.
7. Needless to say - acids.

@extrasonic the true explaination is that sulfur displaces chlorine actually

Hmm I always thought that chlorate and sulfur absorbed water from the air, the acidic sulfur producing chloric acid that causes a violent reaction

if you confine it is the color washed out?

why dont u try "potassiom caromate and glicern"
CODYKORN461 3 years ago
maybe cause there is no substance called potassiom or caromate
