However, when this is applied to an artificial dental base material made of crystallized glass, peeling and cracking occur due to the large difference in thermal expansion between the base material and the glaze when the glaze is fired, and the wettability (compatibility) between the two. Due to poor adhesion, problems tend to occur in terms of adhesion and adhesion.
