The Secret of Egyptian Colors .

 "A lot of people are wondering how the colors of the tombs and temples remain in ancient Egypt, and they kept their luster and splendor, and their colors did not change."

 "Here is a simplified attempt to shed light on the use of colors in ancient Egypt and the technique of their use."
  "Through observation and experience, the ancient Egyptian learned about the properties of minerals and stones from the surrounding environment and worked as much as possible to adapt them and benefit from them to serve the purpose that he wanted and used in the aspects of his life."
 "Among the most common colors in the drawings of temples and cemeteries are dark brown, yellow, green, blue and black. To get these colors, he resorted to the environment and used some minerals to get them from these colors."
 reddish brown, which is the skin color of oxide
             Tri-hematite ferric
 black color hair color of ferrous oxide duo
 Green color of aqueous copper carbonate
  The blue color is one of the royal colors that the ancient Egyptian used in coloring and was difficult to obtain because it was extracted from precious metals such as lapis lazuli or copper sulfate base or blue vitriol

  the yellow color of triple iron hydroxide

 white color limestone calcium carbonate

 "But how did the ancient Egyptian manage to fix these colors and preserve their stability?"

 "These oxides had to be used to dissolve in a liquid in order to be able to spread them on the walls, thus either they would dissolve them in the water as they were suspended in the water, and when they were staining the stone would absorb the water and keep its color layer attached to the surface of the stone."

 Then he uses albumin (egg white) as a varnish that aims to isolate the oxide from the atmospheric effects so that the color does not change due to the interaction of the oxides with the air.

 "Or it dissolves the color directly in the egg white and is used as an oxide carrier medium and is used in coloring and keeps the egg white as a medium and as a color buffer."

 "But why albumin is white."

 "White albumin is a transparent material that does not affect the degree of color and does not interact with it, as when it hardens, it becomes part of the stone and is difficult to fall on its own. Therefore, the colors of the Egyptian inscriptions in our temples and ancient tombs remain fascinated by the world."

 “From more than 4,000 years ago, the ancient Egyptian estimated that he invented the raw materials through which he could leave his civilization to envy us over the whole world and still stands to tell the glory of Egypt from ancient times.”
