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.

COAL BALL PEEL TECHNIQUE. Coal balls are spherical to ellipsoidal masses of calcium carbonate (or calcium magnesium carbonate) in which plant tissues are tree dimensionally preserved, embedded within the carbonate matrix. The carbonate essentially impregnates the residues of the plant cell walls and fills the cell cavities. Concentration of the carbonate occurred by localized precipitation ...

Overview of the warehouse collection of coalball peels assembled by Tom Phillips and students. Dr. Phillips, as he was ever known to most of his students, turned his attention almost exclusively to research on Pennsylvanianage plants, anatomically preserved in coalballs, starting in the early 1970s.

We also introduce a new protocol for the digitization and curation of peels, which is in use at the Phillips Coal Ball Collection at the University of Illinois Urbana‐Champaign. In documenting these protocols, we hope to establish a standardized procedure for working with coal balls.

Acetate paper with a thickness of inches is used to make the first peel of a coal ball after it has been cut with a rock saw. This paper type can also be used for test peels to identify the optimum etching time in acid. The .005inchthick acetate paper is more robust, reducing the chance of damage when removed.

Making a coalball peel. Step 1: After the coal ball has been sawed, it must be ground perfectly flat. A small amount of number 400 silicon carbide grit is used on a sheet of plate glass. Step 2: The grit is moistened to a soupy consistency, and the coal ball is ground for several minutes with a rotating motion. It is then washed thoroughly.

The evaluation of organic material in the coal balls was based on peel studies from 50 randomly selected coal balls from all areas of the crop. Each coal ball regardless of size was considered as one unit. From many of the coal balls numerous peels were obtained but only 2 peels oriented normally to each other were evaluated from each concretion.
