The Phillips Coal Ball Collection is the largest and most significant collection of coal balls in the world. It contains almost 50,000 intact specimens and a quarter of a million "peels"—extremely thin layers (less than a cell thick) peeled from a coal ball slice. Further, the collection represents 80 different coal seams that together ...

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.

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.
WhatsApp: +86 18838072829Coal ball. A Coal ball is a permineralised life form that is full of calcium, magnesium and occasionally iron sulfide. They generally have a round shape. Coal balls are not made of coal, even though they have the name "coal ball". In 1855, two English scientists, Joseph Dalton Hooker and Edward William Binney, found coal balls in England.
