Activated charcoal is a fine, odorless, black powder. It is produced by heating charcoal to an extremely high temperature in an environment without oxygen, such as a tank. Once activated, the powder's pores trap chemicals, making it effective at treating overdoses and chemical poisonings by preventing the body from absorbing the toxic substances.

Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation. The precursor to coal is peat. Peat is a soft, organic material consisting of partly decayed plant and mineral matter.

In 1840, a new method of drilling technology emerged: rotary drilling. This system relied on a man turning, by hand, a drill steel that would slowly work a hole into the rock. This system was originally only used in coal and very weak materials, as the pressure and speed of rotation were not fast enough for good penetration in hard rock.
