Summary

The rapid identification of defects appearing in a finished glaze surface is an important part of maintaining a high level of quality and profitability. Unfortunately, defects such as scum, bubbles, pinholes, and specks can all appear from various sources. By using X-ray diffraction (XRD) and scanning electron microscopy (SEM) to identify the morphology, crystal structure, and composition in the defective area, the problem source can be quickly identified. This paper presents examples of the use of XRD and SEM techniques to diagnose typical defects present in current production pieces.
