Bone ash usually has a density around 3.10 g/mL and a melting point of 1670 °C (3038 °F). Most bones retain their cellular structure through calcination.

Can you get DNA from a burnt body?

In cases of extreme fire impact, only hard tissues (bones, teeth) may be left for DNA analysis. DNA extracted from burnt bone fragments may be highly degraded, making an amplification of genetic markers difficult or even impossible. Furthermore, heavily burnt bones are very prone to contamination with external DNA.
