From Pharaonic Egypt. We all know that many tombs and walls retain their colors dating back more than 3000 BC. The ancient Egyptians were able to invent a color unique to the Egyptians: Egyptian blue, whose chemical name is calcium copper silicate (CaCuSi4O10).
Red is produced by iron oxide, white by gypsum, black by charcoal, green by copper carbon, and yellow by yellow ochre from sandstone. A bag of yellow was discovered in the tomb of Tutankhamun in 1922.
He also invented a color-fixing agent made from egg yolk, and from here the process of painting on walls begins. The stone surface, like the wall, is prepared to be level using limestone. The entire surface is then painted white using a color fixative made from egg yolk.
The Egyptian artist would begin by dividing the wall or painting into squares, depending on the drawing. For example, if the artist were drawing a human, the number of squares would be 19 in length and 6 in width, meaning that the human's total squares would be 114. This is called his scale. If the drawing were an animal the size of a dog, for example, its height would be 6 and its length 10, meaning that the dog's total squares would be 60. This is called his scale. Each drawing had its own scale.
Then, the ancient Egyptian artist would begin drawing the details with great precision and fine lines. The coloring process then began, using watercolors and a fiber brush to color the drawings.
All of these processes were carried out by groups of Egyptian artists with great precision and craftsmanship, and this is evident to this day in tombs, temples, and other works.
