However, because of the small size of the shattered fragments at the impact site, the reconstruction of a sufficient portion of the object to display coning effects may not be possible. As the bullets velocity increases, the central hole becomes smaller, cracking patterns become simpler, and the exit hole becomes wider than the entrance hole.

This document describes the guidelines for assessing fracture features as they relate to forensic glass analysis. Fracture features in a piece of glass reflect the nature of the glass and the direction of travel and velocity of the breaking object. The present study has been conducted for the analysis of glass fracture made by .177 (4.5 mm) caliber Air Rifle. Window panes of 3 mm, 4 mm and 5 mm thickness of 1 ft1 ft dimension were used. Category of 4 mm thickness was taken in two varieties of which one was transparent pane and other was privacy glass.
