Description

Cup glaze firing method

The invention relates to a cup glaze firing method, which is a glaze firing method suitable for firing cups with a height difference at the mouth of the cup, and the cup with the height difference at the mouth of the cup can make drinking more smooth and smooth.

Burning pottery occupies a very important position in Taiwan's traditional culture, and its skills have been passed down and improved for a long time. In addition to the protective effect of the glaze on the green body, the fired utensils are porcelainized into porcelain, which can be waterproof and penetrated, so as to have the function of holding water, and make the surface of the porcelain smooth and hard, and the glaze is fired through the glaze. Fully integrated into the body.

In the conventional technique, during the glaze firing, most of the green bodies will make the bottom feet, and after the green body is glazed, the glaze on the bottom feet will be wiped off, so as to prevent the bottom feet from passing through the glaze and kiln bricks. It is sticky, but it also causes most of the porcelains to have soles, which obviously limits the design of porcelain.

In order to realize the design of porcelain without bottom feet, the green body is fired upside down. Taking the production of a cup as an example, after glazing is applied, the glaze on the mouth of the cup is wiped off, and then the cup mouth is free from the glaze. The part of the glaze is facing down, and it is placed in the kiln on the boron slate surface (kiln brick) for firing. Generally, this method is only limited to the design of a uniform and flat cup mouth. If the cup mouth is designed with an irregular undulating arc, the arc The unevenness of the cup mouth and the contact surface of the kiln brick during the firing process will cause uneven pulling force due to gravity, which will cause the shrinkage rate of the cup mouth to be different, and the green body will be deformed when it shrinks. , causing the finished product to fail.

Therefore, in order to achieve the expected deformation of the green body during firing, a tray with the same shrinkage coefficient as the green body is placed between the green body and the kiln brick during glaze firing, so that the green body does not deform during the glaze firing process. The cup with irregular undulating radian and bottomless feet is designed at the mouth of the firing cup, which is the solution of the cup glaze firing method of the present invention.

The cup firing method of the present invention, the steps of the method at least include: the first step, making a corresponding adobe with a cup as a prototype, and trimming the adobe into a high-bottomed undulating cup mouth with concave and convex. 2nd step, this adobe of molding is carried out bisque firing, after bisque firing is completed, take out china; The 3rd step, glazing medicine is on the outer surface of this china body, so that the complete glazing medicine of the outer surface of this china body Covering, and then wiping off the glaze at the convex position of the cup mouth; the fourth step, making a tray of the same material as the blank, and the tray has a flat surface larger than the cup; the fifth step , put the green body upside down on the flat surface, let the convex position where the glaze has been removed contact the tray, and the concave position of the cup mouth remains suspended, and the tray and the green body are together Enter the kiln for glaze firing, and after the glaze firing is completed, take out the finished porcelain cup on the tray; by the above method, the tray and the china have the same shrinkage coefficient, and shrink uniformly during the simultaneous firing process. So that the finished product is not deformed.

More specifically, the bisque firing temperature of the adobe is set at 750° to 950°, and the firing time is 12 hours. After the bisque firing is completed, the bisque fired body is taken out after cooling to below 150°.

More specifically, the outer surface of the china is dipped or sprayed with glaze.

More specifically, the glaze firing temperature of the tray and the bisque is set to be 1150°~1350°, and the firing time is 15 hours. The finished porcelain cup.

The cup structure of the present invention comprises at least a cup body and a glaze coating: the cup body has an undulating cup mouth, a slightly convex outer edge is formed on the outside of the cup mouth, and the outer edge is undulating along with the undulating cup mouth. The positions are respectively provided with a concave section, an end located at the lowest position of the concave section, two slope sections respectively adjacent to both ends of the concave section and an average height section adjacent to the two slope sections, The cup body also has a cup bottom; the glaze coating completely coats the glaze on all the outer surfaces of the cup body but does not include the positions of the slope section and the average height section.

In a preferred embodiment, the bottom of the cup is provided with a flat surface.
