Why you shouldn't have a naked flame in a powder shoot. Graphic example of what could go wrong!

I wouldnt use "coffee creamer" either.

A rather explosive reaction as shown on good old Mythbusters a few years ago...

what type of powders are flammable


Flour is the obvious one - and people do flour shoots!

Google exploding flour for videos.


And cinnamon evidently... :)

I guess more photographers think of doing a flour shoot than a cinnamon shoot! ;)

(how much is cinnamon?) ;)


Not a bad price really..

A lot more than cheap flour then! ;)

I can't Unsee that

Can you put a warning on these things in future

:/

It does say "Graphic Example" in the title?

Apologies ; I take it back

Custard powder has before now caused very severe explosions. And classically, coal dust, although who would use coal dust for a photo shoot I cannot imagine.

There was CCTV footage of I think it was a custard powder drying tank blowing up somewhere on the net.

Powdered dyes and pigments can ignite too. I used to deal with a big chemical company that made them and the entire factory was designed around the possibility of an explosion.

Anything organic, I'd think.


Not only organic. Try aluminium or magnesium powder!


Please don't try aluminium or magnesium powder.

Various powders - coffee creamers and the like -  have been used for years in pyrotechnics to create a relatively safe, simulated explosion. Please note the term 'relatively'. It is done by pyrotechnicians, on a small scale, in a controlled method and environment. The actual flame is a conflation of millions of minute powder particles each of which ignites and burns out in a microsecond. The combined effect is spectacular but without any real substance.

Metal powders on the other hand burn at much higher temperatures. They have substance and mass and will do serious damage to people and property.

Admittedly, aluminium powder is an ingredient of thermite, but let's not forget it was widely used in photographic flash photography.

I suspect any powder has both mass and substance, so that adds little to the debate.

Sawdust is fun....ex wife was curious about cackling and big fireballs at the bottom of the garden while I was overseeing a bonfire...

Many solids which aren't dangerous in lumps become explosive when divided into fine powder. As others have mentioned metallic dusts are spectacularly explosive (magnesium powder was used as flash powderin small quantities). But paper dust is explosive, as is flour, and even MDF dust.

These powders are not a problem in a pile - they become explosive when mixed with lots of air - like when people throw paint / pigment dust around. All that's required then is a source of ignition - doesn't have to be a flame - a spark is enough. And to add to the fun, the powder rubbing against its container can generate enough static to provide that spark.

Aluminium powder was not used in photographic flash photography, the powder was finely divided magnesium mixed, usually with potassium perchlorate, a strong oxidising agent to propagate the burning process.
