This paper present the main techniques use for glass analysis. Most of the equipment usually found in central group laboratories or in service laboratories gather together in four groups: chemical analysis, microscopy and minerlogical analysis, surface analysis and bubble gas analysis. The principles, detection limits advantages and disadvantages for each method are being discussed. Chemical analysis: traditional wet chemical analysisis rarely used today. The most usual techniques are XRF (x-ray Fluorescene Spectrometry) and ICP-OES (Industively Coupled Plasma Optical Emission Spectroscopy). XRf is the best availbel technique for glass composition monitoring; fast analysis, very good repeatability. ICP-OES is used for non-routine applications.
