A qualitative study for the bond and color of ceramometals. Part II.
Many dentists, porcelain manufacturers, and dental technicians empirically state that repeated firings tend to bleach out or alter the original shade of porcelain. This investigation used a sophisticated colorimeter to resolve the controversy. The effect of temperature rise and number of firings had varying effects on color relative to brand of porcelain and specific alloy.
