Abstract: Soda-lime-silicate (SLS) float glasses with low iron content were obtained from 3 US glass manufacturers. These glasses are possible components in some transparent armor systems. Thus, it is necessary to measure and compare the chemical composition as well as the physical and mechanical properties of each glass to determine if any differences are present that may have an influence on the performance of the transparent armor systems. The results of this study show that all 3 SLS glasses have essentially the same chemical composition and the same physical and mechanical properties, indicating they can be used interchangeably in transparent armor systems without adversely affecting system performance.
