Troy, that's a good point because nitrates sold as stump removers,etc do
have additives to prevent use as an oxidizer.
And as aforementioned powdered sugar has cornstarch in it to prevent
caking. So you may have both contaminated F&OX.
Get pure ingredients from FireFox in Idaho.
Good luck,
Ken

Hi வியா, 9 பிப்,
I’d question the pureness of your KNO3. I’ve done lots of 70:30 candy
mixes and I’ve also done lots of caramelised candy motors back in the day.
Caramelised propellants should actually burn a touch better for burn tests.
Sometimes nitrate oxidizers can be full of crap like clays and anti-caking
agents, but what you’re experiencing sounds even more extreme than typical
contamination.
