These include scanning electron microscopy-x-ray spectroscopy, x-ray fluorescence spectroscopy, mass spectrometry, optical emission spectroscopy and inductively coupled plasma methods.[4]. A radial glass fracture in glass travels some distance depending upon the force of impact, but if it meets another fracture that has been formed earlier, it will terminate at that point. What is the 3r rule for glass fractures? In burglary or rape cases, window pane may be broken and analyzed. Although, density is tested less frequently than refractive indices, it can be used to determine if two glass fragments more likely originated from a different source.[3].

The sequence of impacts when there have been successive penetrations of glass is frequently possible to determine because a fracture always terminates at an existing line of fracture. At this point, the radial and concentric fracture determines the direction of impact. If glassware were to be recycled with glass bottles, the glassware wouldn't melt, and therefore it would contaminate the . Sybirakw 17 lok.
