An accurate means of determining bone age is a goal for forensic scientists. In this study, thermogravimetric analysis (TGA)
has been used to examine pig bone specimens of different post-mortem age. Analysis of bone in both air and nitrogen atmospheres
reveals a decrease in total mass loss as the bones age. Two mass loss steps due to the decomposition of the organic bone components
were observed and show decreasing trends with age for decomposition in an air atmosphere. In a nitrogen atmosphere the decomposition
was observed to be more complex and age dependence of the mass loss for each step was not identified. The TGA data, however,
demonstrates the potential of the technique as a means of estimating post-mortem age of forensic bone specimens.
