Description

Cup glaze firing method and cup structure

The invention relates to a cup glaze firing method and a cup structure, 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.

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 limited to the design of a uniform and flat cup mouth. If the cup mouth is designed with irregular undulating radians, the radian 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. A cup with irregular undulating radian and bottomless feet is designed at the firing cup mouth, which is the solution of the cup glaze firing method and the cup structure of the present invention.

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 outer surfaces of the cup body but does not include the positions of the slope sections and the average height sections.

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

In a preferred embodiment, the glaze coating is dipped or sprayed to coat the glaze on the cup body.
