What is Ancient Egyptian paint made of?
Most modern paints are a mixture of pigment (a finely-ground colouring material, often synthetic and man-made) with some kind of binding agent (glue), plus fluid in the form of water or oil.Ancient Egyptian paints were just the same, although the pigments were restricted to natural substances from Egypt and the desert rather than chemically-produced. The colours were therefore limited: black was from charcoal, white from huntite, calcium carbonate or calcium sulphate, yellow from ochre, reds from heated ochre, blue from azurite (copper carbonate), green from malachite, and so on.Much time was needed to grind a very hard mineral such as malachite to an extremely fine powder, like dust, before it was mixed with a gum taken from plants or animal hides, then diluted with water. Egyptian artists knew how to mix two pigments to create a third (red plus white = pink), but they also understood the idea of putting a wash of one colour over a wash of another to create subtle effects.Before we had paint , we had whitewash. Ground chalk dissolved in water , or dilute clay. Some colors could be added with natural dyes, but it was quite limited.

How do you get copper out of malachite?
In order to extract copper from malachite, the malachite must be heated to a high temperature. This produces a fine black powder (copper Oxide). The copper oxide is heated again to a more extreme temperature, this removes the oxygen, leaving metallic copper.
How could you distinguish copper from galena?
One way to distinguish copper from galena is by conducting a streak test. Galena will leave a gray-black streak, while copper will leave a reddish-brown streak. Additionally, you can perform a simple acid test – copper will not react with hydrochloric acid, while galena will produce hydrogen sulfide gas when exposed to the acid.

It was applied with sticks which were round ended and were made of wood, glass or bronze. Also, henna was used to color hair, lips and nails.
