Bernhard, Tett, List,

If it is carbon, we most probably deal with graphite (as often seen into
e.g. Canon Diablo). Graphite can be tested by various physico-chemical
methods but the simplest tests can be the following:

1) If the surface is large enough, it should prove "greasy" through passing
your finger on it. This may however be not so conclusive and a side test on
a genuine graphite helps.

2) If possible, try to rub the inclusion on a white sheet of paper (or
reverse). Graphite, like a pancil, would leave a gray streak.

Hope this helps.
