Egyptian Blue


PB31 CI#77437

For the ancient Egyptians, blue was a very important color. At around 2600 BC, Egyptian blue enters the historical record. It is considered to be the first synthetic pigment. 

Modern experiments show that Egyptian blue (chemical formula: CaCuSi4O10) can be obtained by heating these chemicals to 800–900°C with the addition of lime, a calcium-containing material, which must have been present in the ancient method, probably as an impurity in the sand.

**When using binders to make the pigments into paints, the color may vary.
