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. The connected solution reactions lead to the formation of a saturation boundary layer, which influences the corrosion behaviour and the glass defect potential. The behaviour of the boundary layers of various refractory/glass melt types are partly complete different. On the one side there are refractory/glass melt combinations which form a relative thick reaction layer, on the other side there are refractory/glass melt combinations with very thin boundary layers. Thick reaction layers affect in the most cases like a protection layer with a good corrosion resistance, but there can be a relative high glass defect potential at operation changes. Thin reaction layers have for the most cases a low glass defect potential, but partly a higher corrosion rate.
