Description

Technical Field

[0001] The present invention relates to the field of ceramics and their preparation processes, and particularly to colored porcelain petals prepared using pine and cypress wooden sticks of special shapes and their preparation processes. Background Art

[0002] In the field of ceramic art and production, the preparation of ceramic products with unique textures and color effects has always been a key direction of research and innovation. As an important category in ceramics, the production process of colored porcelain has been continuously developed and evolved to achieve richer visual effects and higher artistic values. Currently, there are some obvious deficiencies in the production process of traditional colored porcelain petals. In terms of texture formation, most often use mold pressing or manual carving to form the texture of the petals. Although mold pressing can achieve a certain amount of mass production, the formed texture often lacks natural variations and uniqueness, and it is difficult to show the vivid form similar to natural petals. While manual carving can create unique textures, it has low efficiency and extremely high requirements for the skills of the craftsmen, and it is difficult to ensure the consistency and stability of the texture of each petal. In terms of color and decorative effects, the existing colored porcelain petals are usually achieved through traditional glazing and painting processes. However, the colors and spot distributions produced by these methods are often relatively uniform and regular, lacking natural randomness and layering. In recent years, with the continuous improvement of people's requirements for the quality and artistic value of ceramic products, as well as the pursuit of natural and environmental protection concepts, it has become particularly important to develop a new method for preparing colored porcelain petals that can overcome the defects of the above traditional processes. In view of this, this case has arisen. Summary of the Invention

[0003] One object of the present invention is to solve at least the above problems through the colored porcelain petals prepared using pine and cypress wooden sticks of special shapes and their preparation processes.

[0004] To solve the above technical problems, the technical solutions adopted by the present invention are as follows: Colored porcelain petals prepared using pine and cypress wooden sticks of special shapes, the underglaze colored porcelain petals are flat, and the underglaze colored porcelain petals include a blank body and colored glaze and transparent glaze that are sequentially covered on the surface of the blank body.

[0005] Preferably, main vein concave lines are provided on the surface of the blank body.

[0006] Preferably, the raw materials of the blank body, in parts by weight, include the following components: 60 - 65 parts of kaolin, 25 - 30 parts of quartz powder, 14 - 18 parts of albite, and 3 - 5 parts of knot clay.

[0007] Preferably, a deepening colorant and a spot colorant are filled between the colored glaze and the blank body, the deepening colorant is filled in the main vein concave lines, and the spot colorant is distributed on both sides of the main vein.

[0008] Preferably, the raw materials of the deepening colorant, by weight, include the following components: 50-60 parts of dioptase, 15-20 parts of cobalt spinel, 10-15 parts of rosin, 20-25 parts of diatomite, 10-15 parts of feldspar, and 20-25 parts of quartz.

[0012] Step a, raw material processing: Crush, grind, filter, demagnetize, remove iron, and sieve various raw materials of the blank to make slurry, and then process it into clay through pressure filtration and vacuum pumping.

[0013] Step b, petal forming: Process the clay into a blank prototype, and roll the blank prototype with a pine and cypress wooden stick to prepare a petal blank.

The glaze surface is based on a matte light blue, forming a clear lightness contrast with the dark blue veins. The spots on both sides form dark blue spots with light and shadow due to the bubble protrusions. Through the double coloring agent combination of diaphaneity stone and cobalt spinel, a hierarchical blue tone is achieved, enhancing the three-dimensional sense and having a unique glaze surface effect. Specific Embodiments

[0020] The following further describes the present invention through specific embodiments.

[0021] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0022] The colored porcelain petals prepared using special-shaped pine and cypress wooden sticks are flat-shaped underglaze colored porcelain petals, and the underglaze colored porcelain petals include a blank body and a colored glaze and a transparent glaze that are successively covered on the surface of the blank body.

[0023] Main vein concave lines are provided on the surface of the blank body. The main vein concave lines are rolled by a special-shaped pine and cypress wooden stick, and they simulate the main veins in the center of the petals.

[0024] The raw materials of the blank body, by weight, include the following components: 60-65 parts of kaolin, 25-30 parts of quartz powder, 14-18 parts of albite, and 3-5 parts of knot clay. Among the components of the blank body, the high plasticity of kaolin supports the formation of the main veins, the fired whiteness is ≥90%, the Fe2O3 content is <0.1%, the quartz powder enhances the density of the blank body to ensure accurate positioning of the pigment, the albite is a flux to promote the combination of the blank and the glaze and reduce the firing temperature, and the knot clay is a super-high-purity clay to improve the flatness of the clay material.

[0025] A deepening pigment and a spot pigment are filled between the colored glaze and the blank body. The deepening pigment is filled in the main vein concave lines, and the spot pigment is distributed on both sides of the main vein. The glaze surface is based on a matte light blue, forming a clear lightness contrast with the dark blue veins. The spots on both sides form dark blue spots with light and shadow due to the bubble protrusions. Through the double coloring agent combination of diaphaneity stone and cobalt spinel, a hierarchical blue tone is achieved, enhancing the three-dimensional sense and having a unique glaze surface effect.

[0026] The raw materials of the deepening colorant, by weight, include the following components: 50-60 parts of dioptase, 15-20 parts of cobalt spinel, 10-15 parts of rosin, 20-25 parts of diatomite, 10-15 parts of feldspar, and 20-25 parts of quartz. Among the components of the deepening colorant, dioptase provides a deep blue color, and the particles agglomerate to form a matte core. The Cu 2 + ions dominate the main vein coloration. Cobalt spinel aids in coloration, enhancing the blue saturation and being heat-resistant without fading. Rosin decomposes at high temperature to produce gas, and the residual carbon trace deepens the color and forms large bubbles. Diatomite is a matte auxiliary agent, enhancing the matte texture.

[0027] The raw materials of the spotted colorant, by weight, include the following components: 40-50 parts of dioptase, 8-12 parts of rosin, 15-20 parts of peridot powder, 10-15 parts of feldspar, and 20-25 parts of quartz. Among the components of the spotted colorant, dioptase is the blue core and serves as a bubble nucleation site. It combines with the rosin carbon trace to form dark blue spots. Rosin dominates the bubble generation. The residual rosin acid after decomposition reacts with dioptase to form a blue-violet tone. The central bubble wall is semi-transparent due to the enrichment of dioptase, and brownish-yellow floccules remaining from the carbonization of rosin can be seen inside. Peridot powder adjusts the edge tone of the spots to bluish-green, increasing the color hierarchy.

[0028] The raw materials of the colored glaze, by weight, include the following components: 20-25 parts of dioptase, 20-25 parts of chrysocolla, 10-15 parts of talc powder, 10-12 parts of alumina, 8-10 parts of rosin emulsion, 15-20 parts of potassium feldspar, and 10-15 parts of quartz. Dioptase provides a light blue tone and is dispersed in the glaze slurry to form a matte base color. Chrysocolla enhances the light transmittance of the glaze surface and forms a light blue transparent base with dioptase. Alumina increases the hardness of the glaze surface and inhibits the color halo caused by the excessive melting of dioptase. The rosin emulsion decomposes to produce micro-bubbles, enhancing the breathing sense of the matte surface. Potassium feldspar is a flux, controlling the viscosity of the glaze and ensuring the uniform dispersion of minerals, presenting a smooth velvet texture without mirror reflection.

[0036] The preparation process of the colored porcelain petals prepared by using the special-shaped pine and cypress wooden sticks includes the following steps:

[0037] Step a, raw material processing: Crush, grind, filter, demagnetize, remove iron, and sieve various raw materials of the green body to make slurry, and then process it through pressure filtration and vacuum pumping to obtain the clay material;

[0038] Step b, petal forming: Process the clay material into the prototype of the green body, and roll the prototype of the green body with the pine and cypress wood to prepare the petal green body;

[0039] Step c, biscuit firing: The petal blank is put into a kiln for biscuit firing;

[0040] Step d, glazing: Apply deepening colorant, spot colorant, colored glaze and transparent glaze on the surface of the biscuit-fired blank;

[0041] Step e, firing: Fire at high temperature to obtain the colored porcelain petals.

[0042] In step b, the surface of the pine and cypress wooden stick is provided with protrusions, and the protrusions are aligned with the center line of the blank prototype. By rolling the pine and cypress wooden stick on the blank prototype, the main vein concave pattern in the middle is formed. In step d, the deepening colorant is filled into the main vein concave pattern through a dropper, and the spot colorant distributed in a dot pattern is applied on both sides of the main vein concave pattern through a dropper.

[0043] In step e, the firing curve is as follows: Heat up from room temperature to 600 °C at a speed of 5 °C / min, heat up from 600 °C to 1000 °C at a speed of 6 °C / min, heat up from 1000 °C to 1260 °C at a speed of 6 °C / min, keep warm at 1260 °C for 2 h, and cool to obtain the underglaze colored porcelain petals. At room temperature - 600 °C, the rosin decomposes and generates gas, and the cobalt spinel and dioptase in the main vein start to share color, and bubble nuclei are formed in the spot area. At 600 - 1000 °C, the talc melts and spreads, and alumina precipitates nanocrystals, scattering light to form a matte finish. At 1000 - 1260 °C, the dioptase remains light blue in the substrate, the main vein presents dark blue due to the addition of cobalt spinel, and the bubble walls in the spot area are enriched with dioptase, and the color presents dark blue.
