Most glass is mass produced

• true

• false

What type of evidence is glass considered?

• individual

• class

This is the method that if glass fractures align, the fragments are from the same piece. It also can produce individualized glass evidence.

• fracture match

• density match

• refractive match

• shatter match

Applied to a solid, it refers to having atoms that are arranged randomly instead of in a distinctive pattern

• amorphous

• silica

• fracture

• density

This type of glass has two or more panes of glass bonded by a plastic layer. It resists breakage & penetration, and is commonly used for car windshields, entrance doors, & display cases.

• soda-lime

• lead crystal

• heat-resistent

• laminated

• tempered

This type of glass is made using extreme temperatures & chemicals so that it breaks into small chunks or "pebbles." It is commonly used for glass tables, shower doors, or side/rear car windows.
