There are many different types of glass withSPECIAL REPORT/GLASS: Identifying Glass Defects,01/09/2010· However, this possibility was quickly dismissed due to the absence of Na2O and much higher level of Al2O3 in the defect core; these measurements are not consistent with what would typically be found in defects sourced from AZS. The low level of Na2O in the outer zone of the defect was attributed to diffusion from the host glass during the residence time of the defect in the furnace.
