| description | Glass is one of the important physical evidence in forensic science as it can link the
suspect or assailant with the victims and crime science. It is frequently encountered at
crime scenes, particularly those involving motor vehicle accidents or burglaries. This study emphasized on the characterization of two difference types of glass, laboratory and household glassware based on physical properties (thickness, density and refractive
index) and elemental composition by SEM-EDX. Thickness analysis was divided into
three parts, upper, middle and base. The thickness of upper part for laboratory glassware
was found in the range of 1.41 mm - 2.02 mm while for household glassware was in the
range from 3.06 mm - 4.09 mm. Next, the range for middle part of laboratory glassware
was 2.88 mm - 3.48 mm while household between 1.41 mm - 2.02 mm. Then, the
thickness for base part of laboratory glassware was in the range between 0.9 mm - 4.16
mm while for household glassware in the range 4.22 mm - 5.06 mm. The density of
laboratory glassware also different with the household glassware as lab glass has density 2.2 gem 3 while household was 2.4 gem 3 Other than that, the refractive
index for the laboratory glassware showed the range between 1.472 - 1.506 while for
the household glassware gave the refractive index from 1.515 - 1.522. Next, for the
elemental composition detection by using SEM-EDX has identified all expected
elements (Si, Ca, Mg, Na, C, O, Al, K.) except for boron (B). |
