The whole process of mummification took about 70 days. During this time the internal organs were removed and placed in special containers called canopic jars. The brain was removed through the nostrils with a hook and thrown away. The body was covered with natron (a crystallised salt found on the edge of lakes) and was left for 40 days to allow the natron to dry. The body was then stuffed, washed in spiced wine, and perfume was added. Then the body was carefully wrapped in linen bandages. When all this was done, the body was placed in a series of coffins and finally a stone sarcophagus.
