... Ink ...
The oldest of
all ink are the Egyptian writting inks. Mummies dating as far
back as 2500 B.C. were found wrapped in linen marked with an ink
made of iron oxide. Early hieroglyphics (picture symbols) were
written with inks made of soot, water, and vegetable gums.
Secret Messages
Throughout written history, hidden communications
have been sent using invisible ink. One of the earliest methods
used milk to write messages on paper. When the paper was dusted
with soot and the soot blown off, the messages could be read.
