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

The fracture pattern of glass usually has

• Radial and concentric lines
• Concentric lines
• Radial lines
• Directional lines

In reference to the diagram, line 1 is known as __________, and line 2 is known as ___________.

• Radial and concentric
• Radial and directional
• Concentric and directional
• Concentric and Radial

Which glass break was made first?

• A
• B

What type of fracture is this?

• Becke
• Conchodial
• Concentric
• Radial

What will NOT be visible if a glass and a liquid has the same refractive index?

• Conchoidal Lines
• Becke Lines
• Fracture Lines
• Radial Lines

What type of fracture forms on the same side as the impact?

• Radial
• Becke
• Concentric
• Conchodial

Which type of glass fractured this way? 

• tempered (auto)
• window
• crystal

Because glass is a solid with random arrangement of motionless atoms, it is called:

• plasma
• obtuse
• amorphous
• frozen
