The surface smoothness of dental porelain after the use of various staining and glazing technique was examined by scanning electron microscopy. 1. Autogenous self-glazing technique produced a most rough surface. 2. The fixation of stain at $1,500^{circ}F$ followed by thin slurry of glaze powder air fired to $1,800^{circ}F$ produce the most smooth surface. 3. The technique thin sluny of glare powder followed by slurry of stain powder air fired to $1,800^{circ}F$ produce the poor result.
