Abdel-Maksoud and Abdel-Hady [21] said that there is a relationship between the color of bone and exposure to temperature. They also said that thermally altered bone displays surface color and texture changes, which can be a good indicator of the temperature to which the bone was heated, as well as the duration of the heating. Abdel-Maksoud and Abdel-Hady [21], Thompson [48] and Hanson and Cain [49] said that the deposition of carbon in the bone pieces throughout the matrix was noted. This is a very good indicator that the bone was exposed to high temperature. The change of bone color is an indication of the loss of organic and inorganic properties. The authors mentioned above stated that during exposure to heat, especially at high temperatures, the chemical properties of bone alter and structural integrity is impaired or lost. This results from evaporation, organic degradation, and transformation of inorganic matrix. Scanning Electron Microscopy The investigation of the surface morphology (Fig. 5A) of bone using a scanning electron microscope gave more details about the state of the surface [22]. According to Abdel-Maksoud [22] the modern bone has a clearly visible Haversian
