The winner flash powder was Kclo4/Al/S 50/40/10%.Its works best with professional 3-4 micron dark aluminium powder. It was extreme powerful,extreme loud,very bright and absolute stable.Its much better than the magnesium version.The magnesium version Kclo4/Mg/S 50%40/10% has a very pale and small effect in larger firecrackers.Unlike the aluminium which completely different is true.If you want extreme loud,extreme powerful,extrem bright firecrackers with stable mixture Kclo4/Al/S 50/40/10% are the best.This vas the most powerful Kclo4 Al S ratio and much more stronger than standart Kclo4/Al 70/30 and better than Kclo4/Mg 50/50.

The process was easy

-The magnesium powder was milled the possible finest powder

-The magnesium powder was coated with 4% pure boiled linseed oil what dissolved in white spirit than completely dried serval days to get a hard strengh coat.(See Takeo Shimizu fireworks the art science and technique) in Magnesium.

-The potassium perchlorate first heated to make it wapor free.Than grinded down in a poppy seed grinder to the possibble finest powder 3-4 hour grinding.And heated serval times in a hot plate so the dust does not knot.

-The 5 4 1 ratio are a balance-sheet weigh out.

-The potassium perchlorate heated again.And grinded more finer in a mortar.

-Now i used protective gear closed safety glases,and safety gloves!

-The sulfur are grinded and al components are mixed

-All component carefully blended to a homogeneous powder in the mortar.Not grinded!Just softly and carefuly mixed together the ingredients. In two small max 5g dose!

-The flash powder must be always sive in a sieve before use in firecrackers to loosen the dust!

Kclo4 Aluminium sulfure with 4 micron aluminium are much more stable,brighter,mutch more effective and have the same sound so i recommend to use aluminium with sulfur.
