Mummification was when they prepared a dead body for afterlife Only the wealthy could be mummified.
first thing they did while mummifying the mummy was take out all organs. I know this sounds gross but they would take every thing out of the body except for the heart. The kept the heart because they believed they would need it in the after-life . They would put the other organs in caopic jars. the people mummified so the person in there after-life could recognize the body, to get the brain out they would take a hook up the nose and pull down the brain. They did this so the body wouldn't decay.
Secondly they would lay the body down and cover the body with salt, They would leave this out for 42 days.The body would get thinner and skin would turn darker. Third thing is they would clean up the body and wrap it up with linen and charms. These charms are called lucky charms (not cereal)
Fourth thing that they did to the mummy is when it was done drying out the would put the mask over the face and Anubis prayed over the body. The coffin was also carved.How they carved the coffin was they made it very snug like to where your shoulders touched the sides and they made multiple layers of this to kepp the mummy protected. The last thing the did to make a mummy is they painted the coffin face and placed inside multiple coffins & sarcophagus.
