Well I didn't say that the perchlorates weren't toxic. If you handle them safely (as with almost any chemical) it shouldn't be a problem, even for the amateur.

HCl as an exhaust gas may seem bad but it will dilute in the atmosphere quickly when coming out of a rockets rear end, so it's not really that big of a deal.

The instability of perchlorates in solid rocket fuel mixtures would be a much larger concern, which is why most amateur rocketists will problably not use it. Perhaps if you are actually going to space and every last newton of specific impulse counts it could be worth it.

As I remember it, a newton is a measure of force, not specific impulse. Impulse is a measure of power which is the force X distance/ time.

Perchlorate is much more stable compared to the permanganate.
The best flash power is made with perchlorate and dark aluminum, as explanated in this video:



Of course big precautions must be taken when preparing this extremely powerful compound.
Today the pyrotechnic industry prefer to use perchlorates instead black power.

Yes it sure does..

Black or Iron II Oxide. FeO

There are also Metastages of Iron III Oxide which vary in colour from brown- yellow, brown-red and bright red.
