Food grade compositions
I'm not talking about eating fireworks but..
I'm doing my indoor pyrotechnics training in about six weeks, I've often wondered looking at indoor displays and at consumer fireworks such as food
sparklers ( which are basically gerbs ) what they're composed of.
I'm guessing it's a question of choosing nitrates over chlorates and keeping the sulphur content low and probably not using barium or other such
things.
Does anyone know what goes into them?

In common sparklers (the silvery hard mix on copper-steel wire) there is Ba(NO3)2 reason why you have a skull head symbol on the boxes....those are
normaly not for food and birthday cakes, but people don't really care...

I'm quite sure you mean what's called "ice flares" around my place: small fountains that burn with a bright white flame and sparks. They are simple
paper tubes filled with a mixture of high quality nitrocellulose and titanium powder. The nitrocellulose burns cleanly without smoke and the titanium
is not really toxic.

That's the ones - I use a lot of nitrocellulose myself as it's a nice 'safe' indoor pyrotechnic but I hadn't thought about its use in commercial
firework preps. I might investigate further....

The Disney Corporation uses nitrocellulose-based fireworks for their (thrice nightly) shows to drastically reduce air pollution from them.
Homeowners around Disneyland (who bought their homes there decades after the park opened and started the shows) have on occasion filed complaints
and/or lawsuits against Disney for air pollution, but the Air Quality Management District has run tests and found that Disney's new fireworks don't
pollute the air.
The cleaner burning compositions give better colors too with lower amounts of metals.

heads up.. police may suggest mono and di nitrocellulose (yes, ping pong ball grade NC) as high-explosive, their experts, that is. the quality you can
barely even sustain combustion when lit on fire
if you could make a sparkler with lots of fluoride in it, some would probably consider it food grade -lol

Is this a question or a fact?
KClO3 is considered toxic for food!
KClO3 and Na benzoate is a whistle mix...way too energetic to put indoors and in close vicinity to guests placed arround a birthday cake...

Some old fashioned cough sweets used to contain KClO3.

The guy stopped coughing but died from unknown causes    ...yeah old
medecine and remedies... do you really want to try the exotic chemical cures of the begin of the 19th century (like Polonium and the like)?
There are people adept of eating some NaClO2 as drain cleaner for blood circulation...

It didn't work- but that's not the point.
It was food grade KClO3

OK understood .
Anyway better do a suicide with food grade cyanide than with normal cyanide...Cy(a)ni(di)cal humor

Mid nineties I got my first potassium chlorate from pills in a pharmacy in Spain. 99% pure.

Apparently KClO3 is not as toxic as expected...
Belgian Anti-poison Center
It seems non toxic to rabbits...lethal dosis depends on the animal...
Horse 500 mg/kg
Cow 1000 mg/kg
Dog 1200 mg/kg (or cumulative 300 mg/kg during 5 days)
Sheep 2000 mg/kg
Birds 5000 mg/kg
Sadly they don't have the data for humans.
Symptoms of intoxication are far from nice.

Hahahaha.. anyway "food grade" is usually tech grade without heavy metals. Reagent is usually better. My doctor told me choral hydrate would be the
best sleep aid but he couldn't prescribe it because of unavailability. I told him I had a boatload on my shelf and he replied, "weigh carefully.." I'm
considering it but afraid my wife will kick me out if I stay awake (sort of..)
