  • 54. • Restorations that are under fired porcelain often have to be stripped form metal and rebuilt. • Over fired porcelains appears to be glazed and the surface has little or none of the pebbly appearance. • The firing temperature is usually lowered 10 degrees with each correction firing, so that initial build up dos not get effected. www.indiandentalacademy.com
