Examination of test specimens also provides information about the tendency for a particular refractory to form stones or other glass defects. Because this test method is both isothermal and static and since most glass-contact refractories operate in a dynamic system with a thermal gradient, test results do not directly predict service in .

Boundary Layers Refractory/Glass Melt and Glass Defects

In this paper the formation of boundary layers and their behaviour regarding corrosion and glass defect potential of different refractory/glass melt combinations will be discussed. The reaction between refractories and glass melts is determined by the diffusion of the different ions from the glass melt into the refractory material and vice versa.
