Quick Summary
Bright coal is a type of bituminous coal characterized by its fine banding. It typically has a higher moisture, nitrogen, and sulfur content, with a smaller percentage of ash compared to other coal types. Bright coal is classified as a banded coal, meaning it contains varying amounts of vitrinite and opaque material, with anthraxylon alternating with dull coal bands. Warm, moist climates are thought to contribute to the formation of bright coal.123
