The skull is not intentionally broken during cremation. The high temperatures of the cremation process (around 1400-1800 degrees Fahrenheit) cause the bones, including the skull, to become brittle and eventually turn to ash.
The skull, like other bones, is made of a complex structure of organic and inorganic materials. When exposed to intense heat, the organic components (like collagen) burn away, leaving behind the inorganic components (like calcium and phosphate). These inorganic components become fragile and crumble under their own weight, eventually turning to ash.
Factors that contribute to the breakdown of bones during cremation:
- Temperature: The high temperature of the cremation process is the primary factor responsible for bone breakdown.
- Duration: The cremation process typically lasts for 1-2 hours, giving enough time for the bones to turn to ash.
- Bone density: The density of the bones varies based on age, health, and other factors. Dense bones might take longer to break down.
It is important to note that:
- The skull is not specifically targeted or broken during cremation.
- The breakdown of the skull is a natural consequence of the cremation process.
- The remains are reduced to ash and bone fragments, which are typically collected and returned to the family.
