Four ingredients are used in the manufacture of black powder: saltpeter (or nitrates), sulfur (or brimstone), charcoal from coal and water. Basically equal parts of the first three are combined however more saltpeter will produce powder for muskets and even more for pistols. Sulfur and the charcoal acted as the fuel and saltpeter as the oxidizer.

Pelleted powder was used almost entirely in underground coal mines, but now regulations generally prohibit both it and the granular type. Ignition of black powder. Black powder is relatively insensitive to shock and friction and must be ignited by flame or heat. In the early days such devices as torches, glowing tinder, and heated iron rods ...

Coal dust is a finepowdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it.. Grinding or pulverizing coal to a dust form before combusting it improves the speed and efficiency of burning, which makes the coal easier to handle.

The Chinese Invention of Gunpowder, Explosives, and Artillery and Their Impact on European WarfareOverviewThe development of feudalism in Europe was accompanied by the introduction of the heavily armored, horsemounted knight and the fortified castle. While Eastern technology helped pave the way for these developments, it also helped to ensure their eventual obsolescence.

Process. While there are a few ways to approach the recipe, a good gunpowder mix should end up looking like the following ratio: 75% potassium nitrate / salt peter, 15% charcoal, and 10% sulfur. Whether you are dealing with a batch size of one pound or one hundred, the ratio stays the same.

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.

Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...

Same applies here, but for me, it's experimentation. Here are some numbers. Potassium nitrate is about 3/lb and composes 80+% of the mixture. Sulfur is about 2/lb. Charcoal is the most expensive (and minimal use ingredient) at about 15/lb. A pound of homemade powder could be made for sub 5/lb.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
