In a case of forensic investigation, it is important to obtain information on all indications, including those exposed to fire or heat to make an identification during the analysis.
The bones exposed to heat usually present significant alterations in both physical and chemical properties and this can obtaculizar the forensic anthropological analyses and it is for this reason that it is necessary to investigate and to carry out studies that Provide useful and necessary information to make accurate descriptions and compasses that lead to an approximate outcome of what happened in the case. This study was made with fragments of pig bone (Sus scrofa domesticus), them to a laboratory furnace (muffle) at temperatures of 300 ° C, 400 ° C, 500 ° C 600 ° C, 700 ºc, 800 ºc and 900 ° C for exposure periods of 15 minutes and 30 minutes; These fragments were observed in the scanning electron microscope (MEB).
I considered observing and analysing several aspects of macroscopic and microscopic observations such as the following:
macroscopically were color, shrinkage, weight loss and fractures.
Microscopically they were the size and shape of the osteons, the Havers conduits, the fractures and the crystals.
