Egytian Blue Pigment for Creating Handmade Watercolor, Oil Paints, Ink

History: 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.
