Quick Summary

Splint coal is a very hard, dull-looking bituminous steam coal with a laminated structure. It is known for producing intense heat when burned. This type of coal is characterized by its splintery fracture, hence its name.1

Splint coal is a variety of banded coal, distinguished by containing more than 30 percent opaque matter. Banded coals, in general, are composed of alternating layers of translucent material and duller coal. The rank of coal, which reflects its degree of coalification, influences properties like the heat produced during combustion.2
