Fossil shells in pyramid stones sit at random angles - not horizontal like in natural sedimentary rock. This suggests limestone was crushed, mixed into paste & poured into molds. All ingredients were available in Old Kingdom Egypt: limestone powder, clay binder, natron & lime. Davidovits' team recreated matching blocks with period-appropriate materials.

Key facts
- Key ingredients for casting pyramid blocks were available in Old Kingdom Egypt: powdered limestone, clay/kaolin binder, natron (sodium carbonate), and lime
- Fossil shells in pyramid stones are jumbled at random angles, unlike natural sedimentary rock where they lie in horizontal layers
- This disarray suggests limestone was first crushed, mixed into paste, and poured into molds
- The precision of block fitting (not even a hair can be inserted) supports casting against neighboring surfaces
- Archaeologists have not found large numbers of copper chisels or pounding tools at Giza, despite conventional theory requiring extensive carving
- Casting in place would reduce need for metal tools, explaining their absence
- Davidovits team recreated reagglomerated limestone using only natural materials available 4,500 years ago
- The recreated blocks matched the Great Pyramid results with perfect joints
