1. A method for manufacturing a glazed dental prosthesis, the method comprising at least the steps of:
a) providing a dental prosthesis body;
b) position sensitive application of a predetermined amount of a glaze composition to at least a part of the dental prosthesis body surface, wherein the glaze composition comprises a heat sensitive coloring indicator and wherein this step is performed one or more times;
c) controlling the applied glaze composition amount at least at one position of the glazed dental prosthesis body surface by assessing the color intensity at that position; and
d) subjecting the coated dental prothesis body to a heat treatment to form the glazed dental prosthesis, wherein the temperature in the heat treatment is larger or equal to the de-composition temperature of the heat sensitive coloring indicator, wherein at least 90 mol-% of the heat sensitive coloring indicator are transformed into a colorless form.
