What is the physical an optical measurements of glass examinations?
100
Sand
What is the major source of silica?
100
Preparation of raw materials, Melting, Forming, Annealing
and cooling, Warehouse or secondary processing.
What is the five steps in the manufacturing of glass?
100
To identify the glass by physical and optical properties such
as hardness, amorphous structure and isotropism.
What is the first step in glass analysis?
100
These types of measurements are rarely performed in forensic laboratories since they have been mostly replaced
by refractive index measurements.
What are density measurements?
200
The inorganic production of fusion that has been cooled to a rigid condition without crystallization.
What is the definition of glass?
200
These generally form the framework of the glass structure and when cooled quickly after melting, they solidify without
crystallizing
What is former agents?
200
This occurs at temperatures more than 1500 degrees Celsius.
What is the melting process?
200
Type of impact that caused the fracture of glass, the direction of the force, the type of material, source of origin
of the glass fragment, and glass appearance.
What is important information gathered after a physical examinations of glass?
200
This index is defined by the Snell’s law as the ratio of the wave velocity in a vacuum to the wave velocity in the
transparent medium.
What is the intended use classifications of glass?
300
These are components that are added to the formers to lower the melting temperature and to reduce cost of production.
What are fluxes?
300
This occurred in 1500 BC by the Egyptians.
What is the initial formulation of glass?
300
This may help to determine the direction of the force that
produces the fracture.
What is the study of glass fractures?
300
This method uses a furnace to heat the samples and remove the “stress” in the glass.
What is the annealing method?
400
Soda lime, leaded glass, borosilicate glass, special.
What is the main raw material classification of glass?
400
These help to remove bubbles from the molten glass during
its production.
What are refining agents?
400
This is used for decoration, protection or strengthening of the
glass.
What is the coating method?
400
This analysis is used to enhance the value of an
association in forensic glass examinations.
What is elemental analysis?
400
This method, when coupled to an ICP-‐MS (Inductively Coupled Plasma Mass Spectrometry) analysis, usually
provides the best accuracy and precision when the sample
size is limited.
What is the Isotope Delusion method?
500
Sand, Soda ash, and limestone.
What is the main raw materials utilized in the manufacturing of soda lime glasses?
500
This is used to decrease the melting temperature and reduce the cost of the manufacturing process.
What is a cullet (Recycled glass)?
500
Iron (green, brown or blue), manganese (purple), cobalt (blue, green, pink), titanium (purple, brown), cerium (yellow) and gold (red).
What are Common inorganic colorants of glass?
500
This is the best case scenario a forensic examiner could have during physical evaluation of glass.
What is a physical fit or a physical match?
500
This technique has been shown to be the most effective analytical method for the comparison of trace elements in
small glass fragments.
What is ICP-MS (Inductively Coupled Plasma Mass Spectrometry)?
