What was sawdust used for mummification?

Sawdust was used in the mummification process as a drying agent, helping to absorb moisture from the body and prevent decay. It was often mixed with other substances, such as natron, to enhance the preservation of the deceased. This practice was part of the ancient Egyptian belief in preparing the body for the afterlife, ensuring it remained intact for eternity. Additionally, sawdust could have been used to fill cavities or support the body during the embalming process.
