The
History of Paint
Colour
has fascinated culture throughout history, every age and every region
has produced dyes and pigment depending on the available resources.
Colour has been with us for more than 20,000 years. Evidence survives
in early cave paintings and the ancient Chinese are considered to have
brought its manufacture and use to a state of perfection tens of thousands
of years ago.
Colour
was widely used by the ancient Egyptians and was considered to have
magical and healing properties and around this time, 1500 BC, paint
making as an art became quite widely established in Crete and Greece
with the Egyptians passing their skills to the Romans. It was between
600 BC-AD 400 that the Greeks and Romans then introduced varnishes.
For the Aztec Indians red dye was considered more valuable than gold
and both the Indians and Chinese practiced Colour Healing. A 2000 year
old, Chinese chronicle, The Nei/ching, records colour diagnoses.
Yet for
all this it was discovered that none of the worlds civilisations has
named many colours. In the 1960s two anthropologists conducted a worldwide
study of colour naming. Many languages only contained two colour terms,
equivalent to white (light) and black (dark). Of 98 languages studied,
the highest number of basic colour terms was to be found in English
- where we have eleven: black, white, red, orange, yellow, green, blue,
purple, pink, grey and brown. The other millions of colours have 'borrowed'
names, based on examples of them, such as avocado, grape, peach, tan,
gold, etc.
One of
the earliest recorded colour discoveries was made by Plato who discovered
that by mixing two colours, a third is produced, therefore changing
the, 'manufacture', of colour forever.
Prior
to that the earliest cave paintings were made by using iron oxides,
it was the ancient Egyptians who developed other paints from pigments
in the soil (yellow, orange, and red). It was the Romans who gave us
purple, a pound of royal purple dye, required the crushing of four million
mollusks. Cochineal red, discovered by the Aztecs, was made using the
female cochineal beetle. A pound of water-soluble extract required about
a million insects and it was the Spaniards who introduced the crimson
colour to Europe in the 1500's. Later genuine Indian Yellow was produced
from concentrated cows urine which was mixed with mud and transported
to London for purifying, Sap Green from the Blackthorn berry and Sepia
Brown from the dried ink sac of squid.
Paint
is made up of a pigment, a binder to hold it together and appropriate
thinners to make it easy to apply. 5000 years ago Blue Frit was the
first synthetic pigment being produced by the Egyptians from ground
down blue glass. Before the nineteenth century the word 'paint' was
only applied to oil-bound types; those bound with glue were called 'distemper'.
By 1000
B.C. development of paints and varnishes based on the gum of the acacia
tree (better known today as gum arabic) had been developed. At this
time umbers, ocher's and blacks were readily obtainable, new colours
were also discovered - the first was 'Egyptian Blue'; 'Naples Yellow'
dates from around 500 BC and 'red lead' was discovered by accident in
about 2500. White lead occurred naturally but demand encouraged production
of manmade versions. Vitruvius describes production of white lead in
the 2nd century AD.
Before
the 16th century, pigment colour was largely dependant on dyestuffs
which could be grown in, or were indigenous to Europe and similar temperate
regions. Between 1550 and 1850 only the so-called natural dyestuffs
were available but the range was greatly extended with tropical dyestuffs
from Central America and India and elsewhere.
In the
17th century the Dutch greatly increased availability of white lead
and lowered cost by invention of the Stack Process. All white lead paints
included chalk in their undercoats, reserving purer white lead for finish
coats. In1856 the first real synthetic dye, 'Mauveine', was discovered
by Henry Perkins. It was then realized that a great many dyes could
be made synthetically and cheaply.
It was
then that Linseed Oil began being mass produced. They also
had pigment grade zinc oxide - we call it white paint. Using
cast-iron paint mills and zinc-based pigments, industrialists produced
the first washable paint marketed as 'Charlton White' in the 1870's
( the first ready mixed paint was patented by one D.R. Averill of Ohio
in 1867, but it never caught on).
The Sherwin-Williams
company spent ten years trying to perfect the formula where fine paint
particles would stay suspended in Linseed oil. In 1880 they succeeded
in developing a formula that far exceeded the quality of all paints
available at the time.
It was
then that emulsions based on similar formulae, were produced and marketed
as 'oil bound distempers'. By 1880 the new paints were readily available
in tins, in a wide range of colours, and came to be exported all over
the World.
