I think Mumbles is referring to acid-free Sulfur.



Acid free Sulfur is like Oxide free Peroxides. dosent exist so far i know

I had considered that. I also considered the low self-ignition temperature being within reach of friction generated heat. Lactic acid isn't strong enough to protonate the chlorate to chloric acid, which is what causes all the issues from the generation of Chlorine dioxide, so I don't know how reliable that is. Then again it only takes a minute amount to increase sensitivity, but I have a hard time believing a weaker acid, probably present in smaller amounts would cause it to become more sensitive than sulfur/chlorate.



Any Acid even organic such as Ascorbic or Tartaric acid will make extreme sensetive mixtures with Chlorates

If sulfur was totaly free from H2SO4 mixing Chlorates with it should be fine, i can't explain the problem with Sulfides though Posted Image

can that be because of the precence of Lactic acid maybe?

I mostly use KClO3 as my main Chlorine donor, 15 % is to much to be using any BP or so =)

Priming a chlorate star with your prime is a total waste of chemicals. Sorry, but not everyone has money to throw to the wind.
Chlorate stars ignite with ease. They should only be primed with sulfurless meal powder to isolate them from sulfur containing burst charges.



i agree that the Chlorate are vey easy to light, but when you have a comp and uses +50% of KClO4 and just some 15% KClO3 a Chlorine donor then you might need that prime,
and i belive that KClO3 is both cheap and easy to produce yourself?
