Amorphous graphite can be found as tiny particles (-200 mesh, or <75 microns) in metamorphic anthracite or in carbonaceous coal beds. The graphite content varies from 25% to 85% according to the geological environment. Highly Crystalline Graphite. This type of graphite may be referred to as "vein" or "lump" graphite.

An abscess may be deeper, and the skin over it appears red, raised, and swollen. You might also be able to see yellow or white in the lump due to the pus underneath the surface of your skin. Some people also experience fever and chills with an abscess. Often, a boil or abscess will break and drain on its own.
