SOAP
Soap has been with
us in one form or another for thousands of years. The story goes
that in Rome in around 1,000 B.C. at a place called Sapo Hill, the
women were washing their clothes in a small tributary of the river
Tiber, below a religious site where animal sacrifice took place.
They noticed that the clothes became clean upon contact with the
soapy clay which was dripping down the hill and into the water.
It was noticed later that this cleansing agent was formed by the
animal fat soaking through the wood ashes and into the clay soil.
Strangely, in the
first century A.D., the Romans are credited with the making of a
soap-like substance using urine. The ammonium carbonate in the urine
was reacted with oils and fat in wool to form this 'soap'.
During the Eighth Century the Spanish
and Italians began making what was more like modern soap from Beech
Tree ash and Goat fat, whilst the French are credited with replacing
the animal fat with Olive oil.
In England during the 17th century
under King James I, soap makers were given 'special privileges'
and the soap industry started developing more rapidly,
although soaps were generally still made using caustic alkalies
such as potash, leached from wood ashes and from carbonates from
the ashes of plants or seaweed. The soaps made in this way were
harsh and often rather unpleasant.
Soap as we know it
today did not come about until the 18th century, when Nicholas Le
Blanc, a Frenchman, discovered a reliable and inexpensive way of
making sodium hydroxide (caustic soda), or lye as it is known to
the soap maker, which forms the base with which soaps are made to
this day.
Further developments
in soap making were pioneered in Britain during the late 18th century
with the invention of 'Transparent' soap by Andrew Pears, the son
of a Cornish farmer. This refined soap was known then as it is now
as Pears Transparent Soap.
Over the years and
to the present day, opaque soaps have remained the favourite, mainly
because transparent soaps tend to be more expensive and also don't
last as long.
