Description

Technical Field

[0001] The invention belongs to the technical field of ceramic firing, and in particular relates to a method for preparing a glaze-color-matched Ru porcelain plate. Background Art

[0002] Ru porcelain is one of the five famous porcelains of the Song Dynasty in my country, namely "Ru, Jun, Guan, Ge and Ding". Ru porcelain has a fine body and contains trace copper in the body soil. When viewed against the light, it is slightly red. The body color is slightly yellow in the gray, commonly known as "incense ash body". The glaze color is mostly sky blue, powder green and sky blue. The glaze surface is moist and soft, pure like jade, with a distinct butter feeling. The glaze is slightly translucent and mostly milky or crystalline. With the increasing aesthetic demand, the Ru porcelain craft is not limited to a single color and utensil firing. Some artistic innovations have turned to painting on Ru porcelain plates. Special chemical pigments are used to hand-paint and glaze on plain porcelain plates, and then fired at high temperature. This type of flat ceramic craft has a variety of varieties and a wide range of patterns, including figures, landscapes, flowers, insects and birds, fish and algae, and auspicious patterns. The shapes include rectangular, circular, elliptical, multi-square, multi-angle, fan-shaped and other shapes. This type of Ru porcelain craft has innovative requirements for diverse patterns, colorful colors and firing technology.

[0003] The invention patent "A Ding kiln black glaze gold-painted art porcelain plate" with the existing announcement number CN110092647B solves the problem of insufficient aesthetics of existing porcelain plate paintings. Its technical key points are the preparation of porcelain plate raw materials and gold-painted powder raw materials. It also discloses a preparation method of Ding kiln black glaze gold-painted art porcelain plates, including mold making-slip injection-blank and tire repair-normal firing-gold-painting. The Ding kiln black glaze gold-painted art porcelain plates prepared by the above method have a smooth and flat surface without concave and convex marks, and the picture is golden, novel and fashionable, refreshing. The gold-painted powder is not easy to fall off after firing and has good coloring ability. However, the glaze disclosed therein is only gold, involving multiple firing processes and multiple firing temperatures.

[0004] There are also invention patents with authorization announcement number CN113387577B "A blue-green glaze for Ru porcelain and a method for preparing blue-green glazed Ru porcelain", and invention patents with authorization announcement number CN110156437B "A powder-green glaze Ru porcelain and a method for preparing it", both of which disclose the preparation of single-color Ru porcelain products, but do not address artistic requirements such as colorful colors and diverse patterns. In addition, common Ru porcelain handicrafts are all monochrome porcelain, because the firing temperatures and processes of glazes of different colors are different. Summary of the invention

[0005] In order to solve the problem that the Ru porcelain handicrafts in the above-mentioned prior art have single color, simple pattern and complicated firing process, the present invention provides a method for preparing a glaze color-matching Ru porcelain plate.

[0006] The technical solution adopted by the present invention is: A method for preparing a glaze color-matching Ru porcelain plate comprises the following steps: Step 1: Prepare the Ru porcelain plate and let it dry; Step 2: Carve a dent on the dried ceramic tile according to the design image. The dent depth should be greater than 5mm and less than half of the ceramic tile thickness. Step 3: bisque firing of the green body, bisque firing the green body at 750°C to 800°C for 5 to 8 hours; Step 4: Fill the indentations and the panels divided by the indentations with glazes of different colors; Step 5: Let the glazed tiles dry; Step 6: The dried glazed porcelain panels are placed in a kiln for firing. The firing process is to uniformly heat the panel to 900°C in 3 hours, then continue to heat the panel to 1000-1200°C in 3 hours, fire the panel in a reducing atmosphere at this temperature for 5 hours, and then cool the panel naturally with the kiln.

[0007] The glazes of different colors include but are not limited to black glaze, beige glaze, cyan glaze, and purple glaze. In particular, the glazes of different colors have the same firing temperature after being applied on the porcelain plate.

[0008] Preferably, the black glaze comprises the following components by mass: 13 to 23 parts of black stone, 30 to 45 parts of potassium feldspar, 10 to 18 parts of calcite, 8 to 15 parts of iron ore, 8 to 20 parts of wood ash, and 5 to 15 parts of quartz.

[0009] Preferably, the beige glaze comprises the following components by mass: 25-35 parts of potassium feldspar, 30-45 parts of fengxue soil, and 25-35 parts of wood ash.

[0010] Preferably, the components of the cyan glaze by mass are: 30-45 parts of potassium feldspar, 10-20 parts of calcite, 3-10 parts of quartz, 12-19 parts of cyanite, 1-5 parts of iron ore, 10-20 parts of wood ash, and 10-20 parts of soda stone.

[0011] Preferably, the purple glaze comprises the following components by mass: 25-35 parts of potassium feldspar, 30-45 parts of Fengxue soil, 25-35 parts of wood ash, and 5-10 parts of iron ore.

[0012] The beneficial effects of the present invention are: 1. The glaze-colored Ru porcelain plate obtained by the preparation method of the present invention has glazes of different colors, which makes the plate colorful and vivid, and the design patterns are vivid. In addition, the firing temperature of the glazes of different colors after glazing on the plate is consistent, which makes the firing process simple to operate and the parameters easy to control.

[0013] 2. The firing temperature of the glazes of different colors after glazing on the porcelain plate is consistent, which is mainly due to the effect of plant ash. Plant ash is the effect of flux in these glazes, which is actually the effect of calcium element. Some color glazes also contain calcite, which also plays the same role, also to reduce the firing temperature. The present invention utilizes the effect of flux and adjusts the addition amount so that glazes of different colors are fired at the same temperature. BRIEF DESCRIPTION OF THE DRAWINGS
