The most metamorphosed type of coal, it features a carbon content of between 92.1-98%. It features three separate grades: standard, which gets used mainly in power generation, while both high grade and ultra high grade are primarily used in the metallurgy sector.
It differs from the more ordinary bituminous coal by having a greater hardness, higher relative density, and a luster that is often a semi-metallic with a mildly brown reflection. Anthracite coal also goes by the names black coal, hard coal, and stone coal.
Anthracite is possibly best known in United States history when an Athracite vein from an abandoned coal mine that ran beneath the town of Centralia, PA caught fire in 1962. It is still burning as of 2015, and has since turned the town into a virtual ghost town. As of 2013, only 7 people were reported to be still living in the town. At its current rate, it is estimated that the Centralia fire could continue to burn for at least another 250 years.

I purchased this coal over other sellers selling double the amount of coal for the same price because I needed large coal sample pieces. I was disappointed to find that the coal wasn't much bigger than a quarter (see attached picture). If you want small coal pieces, it is better to buy it by the pound. This product is not as large as you would expect.

I present these along with some hematite to my Earth science students and have them do comparisons. I like it because they look similar and both get your hands dirty, but are very different in composition and formation. Once they have had an opportunity to classify the samples and perhaps identify them, I reveal that it was the combination of these two rocks, coal and iron ore, that enabled and drove the industrial revolution.
