The answer comes from the fact that black powder, and other carboncontaining propellants, are fair conductors of electricity. When a material conducts well, it takes a lot more current to heat it up. This is why the lamp wire stays cool and the filament in your light bulb gets white hot.

Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal ), and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.

by J Miller » Mon Oct 01, 2007 3:05 pm. So, and correct me if I'm wrong, black powder does not have enough resistance to heat up and ignite with static electrical sparks. But requires sparks that are from a heat producing source such as primers, flint, or percussion caps to ignite. That seems to be what I'm reading. Joe.

I am well aware of the vast number of hazards involved in the making of black powder. Ranging from, but not limited to, heat, open flames, static electricity even percussion. I will not be doing this in large quantities. A 1/4 of a pound to begin with would be a good starting point. I realize powder mills of the past had a very high accident rate.

Even in a ball mill with lead grinding elements, I would not grind the mixed ingredients. You have a large amount of powder, in a confined space, in a glass container (hmmm, shrapnel!). It's a disaster waiting to happen. Why take the risk, when it's just as simple to grind and ballmill the ingredients separately before mixing?

Ball mills may build up static charge, more so if the drum is made of plastic. This makes grinding flammable or pyrotechnic materials, such as metal powders, organic powders or black powder, extremely dangerous as airpowder mixtures are explosive, while in the case of black powder a singe spark can cause detonation of the powder.
