The Invention Of Paper
Paper was
invented by the ancient Chinese in the 2nd century BC during the Han
Dynasty and spread slowly to the west via the Silk
Road. Papermaking and manufacturing in Europe started in
the Iberian Peninsula, today's Portugal and Spain and
Sicily in the 10th century by the Muslims living there at the time, and
slowly spread to Italy and South
France reaching Germany by 1400. Earlier, other paper-like
materials were in use like papyrus, parchment and vellum.
In medieval Europe, the hitherto handcraft of
papermaking was mechanized by the use of waterpower, the first water paper
mill in the Iberian Peninsula having been built in the Portuguese city
of Leiria in 1411, and other processes. The rapid expansion of
European paper production was truly enhanced by the invention of the printing
press and the beginning of the Printing Revolution in the 15th
century.
The word "paper" is etymologically derived
from papyrus, Ancient Greek for the Cyperus
papyrus plant. Papyrus is a thick, paper-like material
produced from the pith of the Cyperus papyrus plant which was
used in ancient Egypt and other Mediterranean
cultures for writing long before the making of paper in
China.
Papyrus however is a "lamination of natural
plants, while paper is manufactured from fibers whose properties have been
changed by maceration or disintegration.
AD 105 is often cited as the year in
which papermaking was invented. In that year, historical records show that the
invention of paper was reported to the Chinese Emperor by Ts'ai Lun, an
official of the Imperial Court.
Recent archaeological investigations,
however, place the actual invention of papermaking some 200 years earlier.
Ancient paper pieces from the Xuanquanzhi ruins of Dunhuang in China's
northwest Gansu province apparently were made during the period of Emperor Wu
who reigned between 140 BC and 86 BC.
Whether or not Ts'ai Lun was the
actual inventor of paper, he deserves the place of honor he has been given in
Chinese history for his role in developing a material that revolutionized his
country.
Early Chinese paper appears to have been made by from
a suspension of hemp waste in water, washed, soaked, and beaten to a pulp with
a wooden mallet. A paper mold, probably a sieve of coarsely woven cloth
stretched in a four-sided bamboo frame, was used to dip up the fiber slurry
from the vat and hold it for drying. Eventually, tree bark, bamboo, and other
plant fibers were used in addition to hemp.
The first real advance in papermaking came with the
development of a smooth material for the mold covering, which made it possible
for the papermaker to free the newly formed sheet and reuse the mold
immediately. This covering was made from thin strips of rounded bamboo stitched
or laced together with silk, flax, or animal hairs. Other Chinese improvements
in papermaking include the use of starch as a sizing material and the use of a
yellow dye which doubled as an insect repellent for manuscript paper.
