Don't we do enough of that already o subjects that we don't, and can't have a scientifically based answer/conclusion to?
That the science is there, is exactly my point. We can answer this question. However, I've not seen scientific evidence of a static charge of enough energy for a long enough duration to ignite black powder (not including powder dust in the air like a grain silo) being generated by anything the average user does.The science is there, so is the answer.
It is definitely possible to ignite BP with an electrostatic discharge under the right conditions.
However, doing so has no benefit to the muzzleloader shooter.
Was he smoking a cigarette or cigar at the time?There is a guy in TN that emptied some old powder out of several cans into a plastic bowl, was walking to dump it outside and it ignited, causing burns on his upper body. I dont personally know him, just know him on another forum. I have no reason to doubt him, I have seen pictures of the burns on his body.
Speculation is that perhaps the old powder was not coated with graphite and that had something to do with it.

This thread reminds me I have a few I've been meaning to start.
One will be titled "Best cleaning method";
another will be "I love Pyrodex";
another called "why ever use anything except Bore Butter";
and the best of all, "you should always blow down the barrel".
(Zonie absolutely loves me)
you left off a few, like,"is 12L14 Ok for a barrel" "what is the best lube" "WD-40 love it or hate it"

Which would explain why people handling black powder at fireworks manufacturing facilities work very hard stay grounded. It's the fine dust...
And it would explain why straight out of the can BP is tough to ignite with a simple spark, especially at the level commonly found from a human who is part of a common static electricity discharge.
Now I wonder about the occasional granule of 3Fg that gets crushed when I replace the stopper in my horn, and I don't fully empty that horn, but refill as needed, so does a person using the horn develop some fine powder, perhaps lurking in the bottom of said horn? What about the folks crushing the odd granule when using the valve on a flask?
Take some grains of wheat, apply a torch to them in a bowl, they will burn. Let loose a spark among the dust in a grain elevator, and you have a very different scenario.

Don't forget the DOM tubing topic.
Static electricity will most certainly ignite gunpowder.. I have watched demonstrations of this on several occasions at the UK Military College of Science.
I grant you that igniting glazed, corned GP is probably the hardest thing to do, but igniting GP dust is much easier. As has been pointed out, it is the overall energy in the spark that is the main indicator of its ignition potential, but be in no doubt, the temperature created when air ionises (..which is what a spark is!) is well above the ignition point of GP. When you have a low energy spark, the point temperature is usually quickly dispersed, and the ignition potential is low, but this is never a precise indicator of non ignition.
Achieving high levels of static electrical charge is actually quite difficult as in most cases the environment is usually conductive enough to drain it away. Be careful however of extremes of temperature, both high and low when the moisture level is low as this is when static can build up.
Well now, that is going to be a short thread...I would suggest that one of the most important things to help us stay safe is "common sense".
