- Burned bones
- Heat-induced (H-I) alterations
- Colour change
- Shipman et al (1984)
- Occurs due to changes in type-1 collagen and residual carbon
- < 500 C
- Charring
- Brown and black
- Charring
- > 900 C
- Calcination
- White, light grey and blue
- Calcination
- Dependent on temperature, duration, oxygen, soft tissue, body positioning and fuel.
- < 500 C
- Occurs due to changes in type-1 collagen and residual carbon
- Shipman et al (1984)
- H-I trauma
- Fractures
- Shrinkage
- Warping
- Krogman (1939)
- Occurs due to collagen and bone elasticity decrease
- Dependent on temperature, exposure, duration, cooling and soft tissue.
- Occurs due to collagen and bone elasticity decrease
- Crystallinity
- Thompson (2011; 2015)
- Occurs due to changes in bones crystal structure
- Dependent on temperature, duration, soft tissue, fuel and bone density.
- Occurs due to changes in bones crystal structure
- Thompson (2011; 2015)
- Colour change
- Current methods
- Laboratory
- Furnaces, ovens and/or kilns
- Focuses on temperature and duration
- Does not consider the condition, exposure, positioning and/or cooling of bone.
- An overly simplistic view, which suggests these are the only influencing dynamics
- Does not reflect real-life scenarios
- Does not consider the condition, exposure, positioning and/or cooling of bone.
- Does not reflect real-life scenarios
- Variables are controlled and ecological validity is reduced
- Focuses on temperature and duration
- Methods follow trends, which date back to 1984
- Furnaces, ovens and/or kilns
- Field
- Very few
- Mainly for cremation practices and the collapsing of funerary pyres
- McKinley (1997; 2015)
- This is expected due to difficulties in controlling variables
- Mainly for cremation practices and the collapsing of funerary pyres
- Very few
- Methods focus on one variable and use a 'layering' method
- Does not reflect real-life scenarios
- Laboratory
- Fire
- Fire dynamics
- Fuel
- Ambient conditions
- Structural dimensions
- Oxygen availability
- Cannot be replicated with standard furnace testing
- Fire dynamics
- Heat-induced (H-I) alterations
