STAIN PASTE MANUFACTURING METHOD IN DETAL PORCELAIN

摘要

The present invention provides a frit powder and a mixed solution, and also a glaze paste and stain paste produced by using the same, wherein the residue of an organic material is removed so that the expression of black color is prevented, and the bottom of the paste is hardened so that a decrease in surface activity can be prevented. The frit powder used for glaze paste and stain paste according to an appropriate aspect of the present invention is produced from a frit used for glaze paste from among dental porcelains and a frit including paint used for stain paste, wherein the frits have a central particle diameter of 4-5 μm and a largest particle diameter of 25 μm or less, and there are 10% or less frits having a particle diameter of 10 μm or more and 10% or less frits having a particle diameter of 10 μm or more. Moreover, the mixed solution used for glaze paste and stain paste is produced by mixing proplene glycol of 65-75 wt%, distilled water of 15-25 wt%, and glycerin of 5-15 wt%. The glaze paste is produced by mixing the frit powder for glazing with the mixed solution at a ratio of 6:4-7:3. The stain paste is produced by mixing the frit powder for staining with the mixed solution at a rate of 6:4-7:3.
