What all substances were important for mummification mixtures for the pharaohs?

Mummification in ancient Egypt was a very long and expensive process. From start to finish, it took about seventy days to embalm a body. Since the Egyptians believed that mummification was essential for passage to the afterlife, people were mummified and buried as well as they could possibly afford. High-ranking officials, priests and other nobles who had served the pharaoh and his queen had fairly elaborate burials. The pharaohs, who were believed to become gods when they died, had the most magnificent burial of all. In the case of a royal or noble burial, the embalmers set up workshops near the tomb of the mummy. Mummification consisted of many steps. First, the body was washed and ritually purified. The next step was to remove the deceased person's inner organs. A slit was cut into the left side of the body so that the embalmers could remove the intestines, the liver, the stomach and the lungs.  more
