Abstract Scope |
In 2018, the National Institute of Justice funded Florida International University (FIU) to develop glass reference materials (RMs) for Laser Ablation Inductively Coupled Plasma Mass Spectroscopy (LA-ICP-MS). FIU worked with Corning Inc. to develop three RMs. The glasses have three-dimensional defects like bubbles and inclusions which can influence the quantitative measurements done by the forensics community. This study uses light microscopy techniques to quantify the defects in the glasses to inform the decision of further validating the RM. The defects will be imaged using an optical microscope and an open ware software suite. This study will find the count and size distribution of the bubbles in the glass. The bubbles can be formed by unreacted materials decomposing or the solubility of air in the glass decreasing. Both causes change the local chemistry of the glasses. |
