Coal that went to finishing school — hardest, cleanest, and knows it.
means A hard, dense form of coal with high carbon content that burns slowly with little smoke or flame, prized as the cleanest-burning coal there is.
from From Greek 'anthrax' (anthrakos), meaning 'coal' or 'live charcoal' — the same root that gave us the disease anthrax, because of the dark coal-black sores it causes. The gemstone-adjacent sheen of anthracite coal, almost metallic compared to sooty bituminous coal, made 'anthrax/anthracite' feel fitting: something burning like a hot coal, polished and dark.
