Natron in Ancient Egypt: The Sacred Salt of Preservation and Purification

Natron, a naturally occurring mixture of sodium carbonate decahydrate and around 17% sodium bicarbonate, along with small quantities of sodium chloride and sodium sulfate, played a pivotal role in various aspects of ancient Egyptian society. Its uses ranged from domestic and personal hygiene to religious rituals and the sacred art of mummification.

Natron in Mummification

One of the most significant uses of natron in ancient Egypt was in the mummification process, where it served as a desiccating agent. After the removal of the internal organs, the body was packed and covered with natron, which absorbed water and dissolved fats, essentially drying out the body and inhibiting decomposition. After a period of about 40 days, the natron was removed, leaving the body dehydrated and preserved, ready to be wrapped in linen bandages.

Religious Significance

In addition to its practical applications, natron had a spiritual and symbolic dimension. It was associated with the idea of purification and rebirth in the afterlife. The body’s purification with natron during mummification was an essential ritual in preparing the deceased for their journey into the afterlife.

Domestic Uses

Natron was also employed in daily life in ancient Egypt. It served as a kind of ancient soap, used for personal and domestic cleaning. Its mild abrasive properties made it suitable for cleaning teeth and scrubbing cooking pots.


The use of natron in ancient Egypt highlights how the Egyptians harnessed their natural resources for practical, religious, and symbolic purposes. From mummification to household cleaning, this versatile salt was an essential element in ancient Egyptian life. Natron’s use in the preservation of bodies is particularly significant, providing us with the mummies that continue to fascinate us and enrich our understanding of this remarkable civilization.
