Paint has been used by
mankind since before recorded history, first as
decoration, and much later as a protective
coating. The oldest painted surfaces on earth
were colored with a form of milk paint. Cave
drawings and paintings made 8,000 years ago,
even as old as 20,000 years ago, were made with
a simple composition of milk, lime, and earth
pigments. When King Tutankhamen's tomb was
opened in 1924, artifacts including models of
boats, people, and furniture found inside the
burial chamber had been painted with milk paint.
Because the original formula
for milk paint was so simple to make and use, it
was for thousands of years a major form of
decoration throughout the world. Over time, and
in various places, different recipes, including
milk protein(casein), lime, and pigments were
tried, producing varying results in durability.
Many of these coatings also provided
weatherproofing, while others disintegrated,
leaving only a permanent stain on the painted
surface. The variations included adding
substances such as olive oil, linseed oil, eggs,
animal glue, or waxes. Over the centuries,
better recipes were found that could produce a
durable coating, which could last indefinitely.
The colors on the walls painted at Dendaras,
even though exposed to the open air for
centuries, are as vivid today as they must have
been 2000 years ago. |
