A surface coating method for Jun porcelain plate

Abstract

The invention discloses a surface glazing method for a Jun porcelain dish. The surface glazing method comprises the following steps: placing a made dish-shaped blank in an environment with good ventilation at the room temperature, uniformly coating the inner surface of the dish-shaped blank by a layer of petuntse which is 5-10mm in thickness, forming grid indentation in the inner surface of the dish-shaped blank by using a silk screen, controlling the depth of the indentation to 1-3mm, putting the treated dish-shaped blank into a heat-preservation chamber at 50-80 DEG C, allowing to stand still for 10-20 minutes, glazing the inner surface of the dish-shaped blank, controlling the thickness of a glaze in an area without the indentation to 0.5-1.5mm on the basis that the indentation is filled with the glaze, cooling for 20-30 minutes in an environment with good ventilation, and uniformly glazing the inner surface and the outer circumferential surface of the dish-shaped blank, thereby completing glazing. By adopting the surface glazing method, Jun porcelain dish glazing processes are optimized, the glaze adhered to the inner surface and the outer surface of the Jun porcelain dish is at an optimal state, and together with former preheating treatment steps and later sintering molding steps, the made Jun porcelain dish has an optimal aesthetic effect in appearance.

Description

technical field [0001] The invention relates to a manufacturing process of porcelain, in particular to a glaze coating method for Jun porcelain plates. Background technique [0002] At present, there are mainly three kinds of porcelain handicrafts: Jun porcelain, Ru porcelain and peony porcelain. The advantage of peony porcelain is that it takes the natural shape of peony as the main theme and makes the three-dimensional shape of peony flower on top of porcelain. The creative achievement of the organic integration of peony culture has a very high value of cultural research, craft research, artistic aesthetics and collection gifts. Ru porcelain and Jun porcelain also have their own advantages, and Jun porcelain has its own advantages. [0003] With the unique artistic effect of natural kiln transformation, it is unique and outstanding in the porcelain forest. The artistic effect of the glaze color kiln change of Jun porcelain is not artificial, but formed naturally under th...

Problems solved by technology

[0010] The above-mentioned process steps were obtained by the groping of Jun porcelain masters in the past dynasties, and they are also textbook-like classics well known to those skilled in the art. However, the applicant believes that Jun porcelain plates have certain particularities, as the body is thin and the glazed area is large. , conventional glazing methods often lead to more glaze adhesion and poor uniformity on the inner surface. Secondly, considering that the inner surface and outer peripheral surface of the disc parison have different ornamental values, and the inner surface of the disc parison is mainly used as the main surface. The ornamental surface and the rest of the peripheral surface are used as auxiliary. Therefore, according to the conventional operation steps, only a layer of glaze slurry with a suitable thickness is attached to the outer surface of the plain tire, which does not bring good results. Therefore, the applicant It is believed that since the inner surface is the main part, the glazing process of the two should also be different. Therefore, after several years of exploration, the applicant has developed a new glazing method and firing method applied to the plate blank.
