Cleaning coal and soot off your hands? I've been smithing for just over a year now, and I still can't figure out a good way to clean my hands after a few hours working. I've worn gloves, but they make my carpel tunnel return (I had it 3 years ago and it went away after I did something besides laptop things).
Recently, Dunn et al. [22], [23], [24] have conducted experiments on a coaldriven RDE and found that the addition of the coal powder could broaden the operational regimes of the engine. To elaborate the detonation of the coal powder, Dunn et al. [25] established a theoretical model to describe the detonation combustion of the coal powder.

The most energyefficient drying process with ultrasound was found to be the sloping, ultrasonically vibrated trough. However, this process was limited to the use of an initial coal powder feed containing less than 10% moisture. For moisture contents above 10%, a dual drying system could be used. For example, the rotary kiln drier could be used ...
Hand loaders owned their own implements, but paid tool maintenance fees for the operation's blacksmiths and purchased blasting powder from the company. Hand mining required skill, and young miners usually served an apprenticeship under a relative. Lying on their sides, miners first used a pick to undercut the coal three to four feet deep.
Researchers such as Song et al. (2018) have analyzed the use of rock powder as a means to suppress coal dust explosions and found that the predominant mechanism is heat absorption, which inhibits the occurrence of coal dust explosions.
Blinding Cinders: This jagged bit of dusty red coal allows a kobold to breathe a 30foot line of coarse breath weapon deals 1d6 points of fire damage and blinds creatures in the area for 1 round.

Initially, the rock dusting standard in US coal mines was mandated that 65% incombustible content (IC) in nonreturn airways and 80% IC in return airways (Harris et al. 2010).When methane is present in any ventilating current, it requires adding an extra 1% of incombustible material per % methane for air in intakes and adding % incombustible per % methane in the returns (Man and ...
In 2010, scientists analyzed data from 25 studies that looked at the use of coal tar soap for treating psoriasis. In 84% of the studies, results showed that coal tar soap was effective. In 16% ...

A strong, skilled coal loader might fill five or more cars in a day. In West Virginia's colliers, miners were paid 49 cents per ton of clean coal, compared with 76 cents in the unionized mines of Ohio. Under these terms, a hard worker could earn for ten to twelve hours of labor, if the work was steady.
