When acetate peels are prepared from cut coalball slices, dissolved acetate infiltrates microvoids created by acid etching. When a peel is lifted from a coal ball slice, coalified plant remains are wellembedded in the dried acetate film. Coalball carbonate minerals are partially embedded in a similar manner, in particular, the fibrous ...

Anthracite Coal (Hard Coal) Anthracite coal is the highest grade of coal. Anthracite is dark black, very shiny and has a glass like consistency. In the United States the primary source is Northeastern Pennsylvania. It has an average BTU content of 24 to 25 million per ton but can exceed 28 million for the highest quality anthracites.

This embeds the cells preserved in the coal ball into the cellulose acetate. Upon drying, the cellulose acetate can be removed from the coal ball with a razor and the obtained peel can be stained with a lowacidity stain and observed under a microscope. Up to 50 peels can be extracted from 2 millimetres ( in) of coal ball with this method.
