With black powder and its high amount of carbon, a static charge will travel around the outside of the powder grains meeting little resistance so it produces almost no heat. If the static charge did have a significant amount of amperage (which is doesn't), the low resistance caused by the presence of the carbon in the powder would not cause the ...

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.

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.

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?

A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.

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.
