It has been considered that glass to metal joining is realized by the effects of mechanical anchoring and chemical composition gradient. These effects contribute to prevent glass peeling off caused by the difference in thermal expansion coefficient between glass and metal coupled. In order to clarify these ideas, the interfacial microstructures were studied with a high resolution analytical electron microscope. From the experimental results we found that the interfacial zone was composed of a very complex shape acting as the anchoring effect, and the transitional layer of approx.20 nm in thickness between glass and steel substrate was formed in the layer subjected to the chemical effect. The glass region in the transitional layer with the gradient of the iron component into the glass matrix was kept under the compressive displacement of approx.10%.
