Description

Technical Field

[0001] The invention relates to the technical field of ceramic wine bottles, and in particular to a cracked ceramic wine bottle and a manufacturing process thereof. Background Art

[0002] As a unique ceramic artwork, crackle ceramic wine bottles have attracted the attention of many ceramic art lovers with their simple and elegant feeling and unique artistic effect. However, in the traditional production process of crackle ceramic wine bottles, there are two major problems that need to be solved: the crack shape is uncontrollable and the crack glaze is easy to fall off.

[0003] As one of the many glazes, crackle glaze can often attract people's attention with its unique style and artistic charm. The crackle effect of crackle glaze is caused by the mismatch of expansion coefficients between the body and the glaze surface during the ceramic production process. During the cooling process after firing, the glaze layer is subjected to tensile stress and cracks, forming various crack effects, such as fish roe pattern, ice crack, cow hair pattern, crab claw pattern, etc. However, the formation of such cracks is often highly random, making it difficult to accurately control the crack shape, and unable to meet consumers' demand for diversified and personalized crack shapes.

[0004] In addition, the easy falling off of cracked glaze is also a major problem in the production process of traditional cracked ceramic wine bottles. Due to the weak bonding force between the body and the glaze, or the insufficient durability of the glaze itself, the cracked glaze is prone to falling off during use, which not only affects the aesthetics of the cracked ceramic wine bottle, but also shortens its service life. Summary of the invention

[0005] The purpose of the present invention is to provide a cracked ceramic wine bottle and a manufacturing process thereof, so as to solve the following technical problems:

[0013] S5. Place the crack ceramic wine bottle precursor in a kiln and sinter it at 1170-1200° C. for 7-10 hours. After sintering, take it out and cool it for 3-4 days to obtain the crack ceramic wine bottle.

[0015] In a further embodiment of the present invention: in step S1, the method for making the ceramic wine bottle clay blank comprises the following steps:

[0016] Step 1: put the raw materials into a ball mill according to the mass percentage, add water and ball mill for 12-13 hours, then pass through a 120-mesh sieve, and then squeeze and knead the mud to obtain mud strips;

[0017] Step 2: Add sodium carbonate to the mud strips for pulping, the amount of sodium carbonate added is 2-3‰ of the mass of the mud strips, and then perform slip injection molding on the obtained slurry to obtain a ceramic wine bottle mud blank.

[0018] In a further embodiment of the present invention: in the step 1, the amount of water added during the water ball milling is 50% of the amount of the raw material.

[0019] In a further embodiment of the present invention: in step S3, the groove is etched by laser etching.

[0020] In a further embodiment of the present invention, the groove is in a circular, square or triangular shape.

[0021] In a further embodiment of the present invention: in step S4, the thermal expansion coefficient of the inner crack glaze slurry is greater than the thermal expansion coefficient of the outer crack glaze slurry.

[0022] In a further embodiment of the present invention: in step S4, the raw materials for making the inner crack glaze slurry include the following components in terms of mass percentage: 65% crack frit, 20% potassium feldspar, 6% Guizhou soil, 1% bentonite, 5% calcite, and 3% colorant;

[0026] In a second aspect, the present invention further discloses a cracked ceramic wine bottle, which is manufactured by the manufacturing process of the cracked ceramic wine bottle as described above.

[0027] Beneficial effects of the present invention:

[0028] 1. In the manufacturing process of the cracked ceramic wine bottle of the present invention, by etching a plurality of sunken grooves on the surface of the clay blank, on the one hand, the friction between the glaze slurry and the surface of the clay blank can be enhanced, so that the glaze slurry can be more firmly attached to the surface of the clay blank; on the other hand, the glaze slurry will shrink toward the center of the groove when releasing the thermal expansion stress, causing the glaze slurry to break at the outer edge of the groove, thereby generating cracks similar to the shape of the groove, so that the shape and style of the crack can be controlled, which can enhance the aesthetics of the crack style and achieve different visual effects.

[0029] 2. In the manufacturing process of the cracked ceramic wine bottle of the present invention, double-layer glazing is adopted when glazing the ceramic mud blank and the thermal expansion coefficient of the outer cracked glaze slurry is smaller than that of the inner cracked glaze slurry, which can make the crack surface smoother. This is because when sintering is completed and cooled, the thermal expansion coefficient of the outer cracked glaze slurry is smaller, which will cause its shrinkage stress to be smaller than the shrinkage stress of the inner cracked glaze slurry. The deformation of the inner cracked glaze slurry is larger, and when it shrinks toward the center of the mesh, it drives the outer cracked glaze slurry to move with it, so that the edge of the outer cracked glaze slurry curls toward the edge of the inner cracked glaze slurry, thereby producing an inward buckling phenomenon, making the crack line smoother.

After the firing was completed, it was cooled to room temperature, and then the blank was washed with water to remove the surface dust. After drying, a clean clay blank was obtained.

[0107] S3. Making cracked ceramic wine bottle precursor

[0108] (1) Preparation of cracked frit

[0109] Prepare 40% potassium feldspar, 20% calcite, 20% borax, 20% soda ash, 3% lithium carbonate, and 1% strontium carbonate according to mass percentage, then mix these raw materials evenly, smelt them, and then quench them with water to obtain a cracked molten block;

[0112] (4) Glazing the clean clay

[0113] The clean clay body is immersed in the inner crack glaze slurry for 8 seconds and then taken out, and the inner crack glaze slurry is attached to the surface of the clean body, and the crack ceramic wine bottle precursor is obtained after natural air drying;

[0114] S4. Making cracked ceramic wine bottles

[0115] The crack ceramic wine bottle precursor was placed in a kiln and sintered at 11850°C for 8 hours. After the sintering was completed, it was taken out and cooled for 3 days to obtain a crack ceramic wine bottle.

[0116] Comparative Example 2

[0117] Compared with Example 1, the only difference is that step S3 is cancelled, and the other steps remain the same, and finally a cracked ceramic wine bottle is obtained.

[0118] Comparative Example 3

[0119] Compared with Example 1, the only difference is that step S4 is replaced by step S3 in Comparative Example 1, and the other steps remain the same, and finally a cracked ceramic wine bottle is obtained.

[0120] First, the cracked ceramic wine bottles prepared in Examples 1-5 and Comparative Examples 1-3 were observed, the crack conditions on the surfaces of the cracked ceramic wine bottles were recorded, and the results were listed in Table 1. Table 1 is as follows:

[0121] Table 1

[0122]

[0123]

[0124] By analyzing the situation records in Table 1, it can be known that, compared with Comparative Examples 1-2, the crack patterns on the surfaces of the cracked ceramic wine bottles obtained in Examples 1-5 and Comparative Example 3 are more regular and beautiful, and the shapes are similar to the shapes etched on the surface during the preparation process, which are different from the irregular mesh cracks in the prior art; therefore, it can be known that the present invention can make the crack shape controllable by etching grooves on the surface of the ceramic wine bottle mud blank, thereby achieving a more beautiful and unique style effect. This is because, when cracks occur, due to the setting of the grooves, the glaze slurry will shrink toward the center of the groove when releasing the thermal expansion stress, causing the glaze slurry to break at the outer edge of the groove, thereby generating cracks similar to the shape of the groove;

[0125] At the same time, compared with Comparative Examples 1 and 3, the mesh edges (i.e., crack lines) of the mesh cracks on the surface of the cracked ceramic wine bottle obtained in Examples 1-5 are inward-curled and smooth, while the mesh edges of the mesh cracks on the surface of the cracked ceramic wine bottle obtained in Comparative Example 2 are not inward-curled or outward-curled and are relatively smooth. It can be seen that when double-layer glazing is adopted when glazing the ceramic mud blank and the thermal expansion coefficient of the outer crack glaze slurry is smaller than that of the inner crack glaze slurry, the crack surface can be made smoother. This is because when sintering is completed and cooled, the thermal expansion coefficient of the outer crack glaze slurry is smaller, which will cause its shrinkage stress to be smaller than that of the inner crack glaze slurry. The deformation of the inner crack glaze slurry is larger, and when it shrinks toward the center of the mesh, it drives the outer crack glaze slurry to move with it, so that the edge of the outer crack glaze slurry curls toward the edge of the inner crack glaze slurry, thereby producing an inward-curling phenomenon, making the crack line smoother.

[0126] Then, the cracked ceramic wine bottles prepared in Examples 1-5 and Comparative Examples 1-3 were subjected to a glaze strength test to detect the adhesion of the cracked glaze (glaze on the surface of the cracked ceramic wine bottles) on the surface of the wine bottles. The test method was based on GBT9286-1998, and the shedding rate of the cracked glaze on the surface of the cracked ceramic wine bottles was recorded. The results are listed in Table 2, which is as follows:

[0127] Table 2

[0128] Crack glaze shedding rate (100%) Example 1 0.12 Example 2 0.15 Example 3 0.13 Example 4 0.16 Example 5 0.17 Comparative Example 1 4.56 Comparative Example 2 3.01 Comparative Example 3 2.96

[0129] By analyzing the data in Table 2, it can be found that compared with Comparative Examples 1-3, the crack glaze shedding rate on the surface of the cracked ceramic wine bottle obtained in Examples 1-5 is significantly lower, which indicates that its adhesion is better. This is because, on the one hand, the setting of the groove increases its surface roughness and can improve the adhesion ability of the glaze. On the other hand, the glazing method of two layers of glaze slurry can make the outer layer of crack glaze slurry buckle inwardly outside the inner layer of crack glaze slurry, further improving the firmness of the crack glaze.

[0130] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
