NATRON is used. Natron crystals are packed around the body. The crystals absorb body fat and fluids and keep the body from decaying. After being treated for about 40 days, the corpse is washed and dried.
Stuffing
Because the body has lost much of its mass, resin-stained clothes or bits of sawdust are used to pack the corpse, which by now has also lost its eyeballs. Pieces of cloth are stuffed in the eye sockets and painted black. At this point, the corpse's lips and cheeks are painted.
Oiling the Body
This elaborate process includes, massaging, perfuming, and anointing (blessing with oil) the corpse.
Coloring
After the nose and mouth are filled with cloth scraps to restore the shape of the face, the body is colored. Men are colored red; women are colored yellow. After the coloring, resin is poured into body cavities.
Arrangement of the Body
Depending on which period of Egyptian history the deceased lived in, the arms are either placed to the side of the corpse, folded on its chest, or placed with hands on shoulders.
Wrapping
The body is wrapped in several layers of fine linen; and various body parts receive particular attention. This process takes two weeks, after which a resin is added to the bandages.
Funerary Mask
A mask, sometimes made entirely of gold, is fitted to the mummy's body. Symbols of gods often adorned masks.
Burial of Waste
All materials used to prepare the corpse (such as natron and bloody linen) are placed in a jar and buried away from the mummy's tomb.
