In forensic science, glass evidence plays a pivotal role in supporting investigations This analysis may give an indication of common origin but is not an absolute identification By analyzing its physical properties—such as refractive index, density, and fracture patterns—investigators can establish crucial links between crime scenes and suspects.

Submitted samples from a crime scene must first be confirmed as glass
Differentiating glass from plastic is done by examining relative hardness, solubility, and observation with a polarized light microscope.
There are several measurable characteristics that may be available for laboratory analysis and comparison between and known and questioned sample The examiner may attempt to determine if two pieces of glass are a physical match. Explore the techniques and tools used in glass analysis to help investigators solve crimes and unravel mysteries. Also, glass fragments can help police determine which direction the first bullet was fired through the glass
These clues can be gathered through the analysis of even the smallest fragments of glass Refractive index (ri) has been determined by immersion method in the initial years of forensic glass analysis This method of determining ri was based on the technique described by winchell and emmons in 1926. Study with quizlet and memorize flashcards containing terms like glass is defined as which of the following?, what is the process used to increase the strength of glass?, what kind of glass is commonly used in vehicle windshields
Glass fragments of many sizes, including microscopic, can be compared
