Study Notes

The order of bullet impact on a window pane can determine the aggressor.
Fractures on safety glass are often incomplete, with radial and concentric cracks not extending fully.
Laminated glass does not shatter and cracks may also be incomplete.
Tempered glass breaks into small pieces without sharp edges.
Fluorescence, spectrographic, X-ray diffraction, density, and polish marks analysis are all tests used to determine glass composition and properties.
