“…The formation of new mineral phases, like CaO and β-TCP, is dependent on the Ca/P molar ratio (>1.67) [30]. The chemical conversion of CHA to β-TCP was suggested to occur in (non-human) bone heated at temperatures from 600 °C and higher, by Civjan et al and Bonucci et al [31, 32]. These findings were not confirmed by X-ray diffraction (XRD) experiments carried out by Rogers et al, who heated human cortical bone sections in air in the range of 200 to 1200 °C; this study only reported the presence of CHA and CaO [33].…”

Literature on luminescent properties of thermally altered human remains is scarce and contradictory. Therefore, the luminescence of heated bone was systemically reinvestigated. A heating experiment was conducted on fresh human bone, in two different media, and cremated human remains were recovered from a modern crematory. Luminescence was excited with light sources within the range of 350 to 560 nm. The excitation light was filtered out by using different long pass filters, and the luminescence was analysed by means of a scoring method. The results show that temperature, duration and surrounding medium determine the observed emission intensity and bandwidth. It is concluded that the luminescent characteristic of bone can be useful for identifying thermally altered human remains in a difficult context as well as yield information on the perimortem and postmortem events.Electronic supplementary materialThe online version of this article (doi:10.1007/s00414-017-1546-1) contains supplementary material, which is available to authorized users.

“…Because studies have shown that only hydroxyapatite persists in calcined remains heated beyond 800°C (21–23), cremains weights appear to be measuring the remaining bone mineral fraction. Thus, factors that affect bone mineral density in vivo should also be reflected in cremains weight.…”

The reduction of modern commercially cremated remains into a fine powder negates the use of traditional methods of skeletal analysis. The literature on the use of cremains weight for estimating aspects of the biologic profile is limited, often with conflicting results. This study re-evaluates the value of weight in the assessment of biologic parameters from modern cremated remains. A sample of adults was collected in northern California (n = 756), with a cremains weight averaging 2737.1 g. Males were significantly heavier than females (mean = 3233.2 g versus mean = 2238.3 g, respectively; p<0.001). Comparison of this sample with other previously reported samples from southern California, Florida, and Tennessee indicates a consistent sex difference, with the most similar mean values to the Tennessee study. Although cremains weight decreases with age as expected, the relationship is weak; thus, cremains weight cannot accurately predict age-at-death. While sex estimation shows considerable accuracy (86.3% for males and 80.9% for females), sectioning points may be population specific.

“…Although studies thus far have been unable to specifically pinpoint required exposure times or temperatures for causing these changes, some researchers have been successful in identifying temperature ranges with which they can be associated (Bonucci and Graziani, 1975;Civjan et al, 1971;Holager, 1970;Rootare and Craig, 1977;Shipman et al, 1984;Thompson, 2004).…”
