Forensic Analysis of Glass

Glass which is strengthened by introducing stress through rapid heating and cooling of it's surface.

• Soda Lime Glass
• Leaded Glass
• Tempered Glass
• Laminated Glass

When a bullet penetrates a panel of glass, it leaves a crater shaped hole that

• is wider on the entrance side
• is smaller on the entrance side
• Forms randomly
• Both B & C
