The following is an excerpt from Heritage Key, which chronicles a Swiss team's efforts to perfect the exact same mummification process the Egyptian's used thousands of years ago, to examine how much the mummification process degrades DNA, how tissue reacts during the process, and how ancient cultures tried to preserve their loved ones after death:
So far the Swiss team has met with mixed results. After 440lbs (60kg) of salt mixture and 80 days, magnetic resonance still shows signs of moisture within the tissue. Dr. Rühli had expected the process to take around 70 days, and plans to continue for another month. Sometime this winter the team will attempt to mummify another body part, this time accounting for the role heat plays in mummification.
The article states that the Swiss team is basing their salt mixture on "a mid-1990s United States study, which tried to determine the 'magic formula' used by ancient Egyptians to dry out bodies before burial," but the details of the U.S. study are not given.
If Emily Teeter were in charge of that U.S. team back in the 90s, there would have been detailed notes and documents of how they went about mummifying an entire body using ancient methods (no offense to that team, of course). What is the purpose of keeping information to yourself? There's no progress in that. And how do you know you're progressing or just repeating experiments needlessly without such references?
