Origin of defects related to the corrosion of the refractories in lead crystal glass

This paper reports mechanisms of corrosion of the refractories used in indu strial melting of lead crystal glass hollowware, and some chosen examples o f defects linked to this corrosion. Sections prepared in worn refractories from dismantled furnaces and in different defects were characterised by SEM (scanning electron microscope) microanalysis.
