How long was immersion in natron recommended during embalming?

The correct response indicates that immersion in natron during embalming was recommended for a period ranging from twenty to seventy days. Natron, a naturally occurring mineral composed mainly of sodium carbonate and sodium bicarbonate, was historically used in ancient Egyptian embalming practices due to its desiccating properties. This extended immersion time allowed the natron to effectively dehydrate the body, drawing out moisture and preventing decomposition.

The duration is significant as it establishes a balance between preservation and the potential for tissue alteration, which could occur if the body remained in natron for too long. The period of twenty to seventy days was optimal for achieving thorough drying without causing excessive damage to the tissues, thus ensuring that the body would be well-preserved for burial practices. This knowledge reflects the importance of proper embalming techniques in maintaining the integrity of the deceased for final rites.
