The stone was cut with remarkable accuracy, allowing tight joints that have largely held for millennia despite weathering and seismic activity. Workers could extract massive blocks close to the construction zone, reducing the need for heavy hauling over long distances.

Workers likely used copper chisels, dolerite pounding stones, and wooden wedges soaked in water to fracture massive blocks. Transportation relied on Nile barges during the annual flood, when water levels rose close to the quarry sites.
Chemical Composition Insights Modern spectroscopic techniques have identified traces of magnesium and aluminum in the mortar, suggesting the inclusion of natural pozzolanic materials. Most of this elegant casing was removed over centuries for building projects in Cairo, revealing the rougher core beneath.

This core casing stone, often referred to as Tura limestone, provided a smooth, reflective surface that originally made the structure gleam white under the desert sun. The journey could take weeks, involving coordinated crews for loading, hauling, and unloading.
