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.

Embodiment 1

[0026] Embodiment 1. A glaze coating process for the surface of a Jun porcelain dish. Place the prepared dish-shaped body in a ventilated environment at room temperature, and evenly apply a layer of porcelain clay with a thickness of 5mm on the inner surface of the dish-shaped body. The wire mesh presses a grid-shaped indentation on the inner surface of the disc-shaped green body, and the depth of the indentation is controlled at 1mm, and then the treated disc-shaped green body is placed in a heat preservation room at 50°C for 10 minutes , and finally apply a layer of glaze on the inner surface of the disc body to ensure that the glaze fills the indentation and control the thickness of the glaze on the non-indentation area to 0.5 mm, and then dry it in a ventilated environment for 20 minutes. Then apply a layer of layer glaze on the inner surface of the pan-shaped body, and evenly apply a layer of bottom glaze on the outer peripheral surface of the pan-shaped body. This time, t...

Embodiment 2

[0029]Embodiment 2. A glaze coating process for the surface of a Jun porcelain dish. Place the prepared dish-shaped body in a ventilated environment at room temperature, and evenly apply a layer of porcelain clay with a thickness of 10mm on the inner surface of the dish-shaped body. The screen presses a grid-shaped indentation on the inner surface of the disc-shaped green body, and the depth of the indentation is controlled at 3mm, and then the treated disc-shaped green body is placed in a heat preservation room at 80°C for 20 minutes , and finally apply a layer of glaze on the inner surface of the disc body to ensure that the glaze fills the indentation and control the thickness of the glaze on the non-indentation area to 1.5 mm, and then dry it in a ventilated environment for 30 minutes. Then apply a layer of layer glaze on the inner surface of the disc-shaped body, and evenly apply a layer of bottom glaze on the outer peripheral surface of the disc-shaped body. This time, th...

Embodiment 3

[0032] Embodiment 3. A glaze coating process for the surface of a Jun porcelain dish. Place the prepared dish-shaped body in a ventilated environment at room temperature, and evenly apply a layer of porcelain clay with a thickness of 8mm on the inner surface of the dish-shaped body. The wire mesh presses a grid-shaped indentation on the inner surface of the disc-shaped green body, and the depth of the indentation is controlled at 2mm, and then the treated disc-shaped green body is placed in a heat preservation room at 60°C for 15 minutes , and finally apply a layer of glaze on the inner surface of the disc body to ensure that the glaze fills the indentation and control the thickness of the glaze on the non-indentation area to 1 mm, and then dry it in a ventilated environment for 25 minutes. Then apply a layer of layer glaze on the inner surface of the disc-shaped body, and evenly apply a layer of bottom glaze on the outer peripheral surface of the disc-shaped body. This time, t...

Abstract

The invention provides a surface glazing technology for a jun porcelain plate. A prepared plate-type green body is put in a ventilation environment at the room temperature, the inner surface of the plate-type green body is uniformly coated with a petuntse layer, a gridded indentation is pressed on the inner surface of the plate-type green body by a screen mesh, depth of the indentation is controlled in a range of 1-3 mm, the treated plate-type green body is placed in a thermal insulating chamber at the temperature of 50-80 DEG C and left to stand for 10-20 min, then the inner surface of the plate-type green body is coated with an overglaze layer, the thickness of glaze applied to the area without the indentation is controlled in a range of 0.5-1.5 mm on the basis that the indentation is filled with the glaze, the plate-type green body is aired for 20-30 min in the ventilation environment, the inner surface of the plate-type green body is coated with the overglaze layer again, meanwhile, the peripheral surface of the plate-type green body is uniformly coated with a ground glaze layer, and glazing is finished. The glazing technology for the jun porcelain plate is optimized, the glazeattached to inner and outer surfaces of the jun porcelain plate is in the optimum state, and through matching with the optimal overglaze and ground glaze materials, the appearance of the jun porcelain plate prepared with the technology achieves the best aesthetic effect.

Description

technical field [0001] The invention relates to a manufacturing process of porcelain, in particular to a glaze coating process 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 t...
