  The approach based on selected set of samples and selected set of analytical
tools occurred quite efficient when applying to amorphous carbons thus leading
to a transformation of the current representation of the issue based on
particulars into that one based on a limited set of fixed commonalities. The
approach first part implies a set of different origin solid samples. The second
part concerns different analytical tools. The combining part means the
application of each tool to the whole set of samples. In the current study two
natural amorphous carbons shungite carbon and antraxolite, as well as two
engineered products carbon blacks CB632 and CB624, all of the four belonging to
the elitist highest-carbon-content species, were subjected to analytical study
by using modern structural and compositional analytical techniques. The
approach has allowed disclosing steady points that are common to the whole
class of this carbon allotrope and that may lay the foundation of a consolidate
representation of what are amorphous carbons.
