'cookieDomain': 'fagerdalagroup.com' Glass analysis includes determining the type of glass based on glass fragments. The glass fracture pattern analysis is very useful to establish the sequence of events and to link together items of evidence and it is of paramount importance in such cases where firearm is used. Broadly, these can be split into: complete: all the way through the bone. [3] The density of a glass fragment will depend on the batch characteristics and composition. 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.

Hyun Woo Sung Married, The glass fragments are immersed in the liquids, often oils, and Becke lines are examined according to the Becke line test. However, as the velocity of penetrating projectile decreases, the irregularities of shape of hole, and its surrounding cracks increases so at that point the hole shape may not determine the direction of impact.
