Natron salt formula11/11/2023 ![]() The fire oxidizes and converts the rocks into a powdery residue, and that is lime. Lime is a powdery residue obtained by burning and reducing to ashes sedimentary rocks such as limestone and dolomite. More lime, the mineral which binds, was added. Natron is found in very great quantities in the desert and in Wadi-El-Natron. Salt is a very reactive substance that has a petrifying effect, which is why it is used to avoid the putrefaction of organic tissue (mummification). ![]() Next, a substance called Natron salt (sodium carbonate) was poured in. Imhotep’s men began disaggregating the clayish soft rock with its water, until the lime and the clay separated, forming a mud with the fossil shells at the bottom. Shallow canals were dug in the soft limestone along the Nile, forming ideal basins for producing large quantities of muddy limestone. Soft limestone can be easily disaggregated either under pressure or by diluting it in water. To build the Step Pyramid, Imhotep located a quarry of soft limestone, just one kilometer from the construction site to provide the raw material he needed to cast millions of modular stones. This meant preparing a more sophisticated type of mold to produce inclined limestone blocks following the slope of the pyramid, adding new ingredients to the mixture to yield a higher quality stone. When all the blocks of the core were set in place, a layer of casing was applied. ![]() Imhotep had two different chemical formulas: a very simple one for the casting of the limestone core blocks, and another one to produce the high quality stones of the exterior layer.
