DISCOVERY OF THE MONTH
In February 11, 1808: Anthracite coal is first burned & discovered as a heating fuel
Anthracite is a hard natural coal that burns slowly and gives intense heat. It is a hard, compact variety of mineral coal that has a high lustre. It has the highest carbon count and contains the fewest impurities of all coals, despite its lower calorific content. Anthracite coal is the highest of the metamorphic rank, in which the carbon content is between 92% and 98%. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame.
