Why didn't the experts at the city of the dead right down the chemical formula for their preservatives?
The experts at the city of the dead may not have written down the chemical formula for their preservatives due to various reasons such as secrecy to protect their trade secrets, the use of symbols or pictograms instead of written formulas, or the lack of a standardized writing system for chemical formulas at that time. Additionally, they may have relied on oral tradition or passed down the knowledge verbally rather than in written form.
