carbonaceous inks
A general term used in describing a group of inks
produced from finely ground carbon or a similar
substance, e.g., soot or lampblack, and which are
jet black and very stable. A glutinous substance
is used as a binder. Such inks are the simplest of
all inks to produce and have been known from the
earliest times. They have no destructive
influences on paper but they do present
difficulties to restorers because they are so
easily affected by water. The carbonaceous inks
may be subdivided into CARBON INK ,CHINESE INK , and the
SEPIA INKS .
