Coal can also be cut into thin sections, as in mineral and rock petrography. A thin section is a thinly cut sample, which is epoxied on to a thin glass plate. The sample side is then ground down and polished to the point at which light is visible through the glass and sample, which allows petrographers to see great details in the samples.

Maceral Analysis Pearson Coal Petrography We

Petrography is used by coal-producers to evaluate the nature of coal deposits, to confirm the quality of vessel or train cargoes, and to show the uniqueness of a specific product relative to another. Steel producers use petrography as an aid in the design of coking coal blends, to help in trouble-shooting problem-cokes, and to confirm the nature of vessel or train cargoes.
