Just tried the following mixtures (1-2 grams):
- KNO3 + S : needed a Bunsen burner to ignite: VERY slow.
- KNO3 + S +C (black powder) : hardly lit by lighter but self sustaining
- KNO3 + sugar: can only be lit with bunsen burner and not self sustaining and very smoky
- KClO3 + S (mixed slowly within fumehood because of possible spontaneous ignition) : lit by lighter , rather slow but faster than KNO3, blue flames
- KClO3 + sugar : very fast burns with purple flame, filled the fumehood with smoke
Fortunately I have no P
So KClO3 is a much better (and more dangerous !) oxidizer , NEVER mix with P and NEVER use it for firecrackers.
Making you own firecrackers is a bad idea anyway, lots of prople lost some fingers or even eyes.
I use this only in small quantities for reaction speed and flame color tests.
