Pen and ink
Inks derived from carbon
suspended in water, have been used since the Renaissance. Iron
gall ink was made from ground gall nuts or oak apples and iron
sulphate, light washes were made from very diluted inks. Natural
ink occurs in squid (the 'ink sac' - used in the sea to scare
off attackers) and was used in the 19th century. Reeds or bird
quills (goose, turkey or crow) were used as pens before their
manufacture in metal. An excellent method of achieving gentle
tones swiftly, but skill and care is needed as marks produced
are indelible.
