Description

Technical Field

[0001] The present invention relates to the technical field of molding clay or other ceramic components, and in particular to a colored glaze decoration process and equipment for exquisite ceramic vases. Background Art

[0002] The exquisite ceramic vase is a ceramic artwork that combines traditional porcelain making technology with exquisite decorative art. It is called glass-inlaid porcelain. It combines the strengths of blue and white porcelain craftsmanship and the wonders of carving art.

[0003] The colored glaze decoration technique used on the exquisite ceramic vase is a perfect fusion of underglaze blue and white porcelain and exquisite craftsmanship. This technique not only showcases the profound beauty of blue and white porcelain, but also incorporates the delicacy and agility of exquisite craftsmanship. Through the technique of hollow carving, delicate holes are formed on the porcelain, making it more visually transparent and showcasing an ever-changing beauty through the interweaving of light and shadow. Existing colored glaze decoration techniques for exquisite ceramic vases can lead to excessive or insufficient melting of the glaze due to lax temperature control during the firing process. Excessive melting of the glaze will cause bubbling on the glaze surface, while insufficient melting of the glaze may affect the smoothness and gloss of the glaze surface. These phenomena will affect the quality of the exquisite ceramic vase. Summary of the Invention

[0004] The purpose of the present invention is to provide a ceramic exquisite vase colored glaze decoration process and equipment, aiming to solve the problem that the temperature control of the existing ceramic exquisite vase colored glaze decoration process is not strict, resulting in excessive or insufficient melting of the glaze.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a process for decorating a ceramic exquisite vase with colored glaze, comprising the following steps:

[0006] Obtaining porcelain clay, glaze and blue-white colorant, and making the porcelain clay into a vase blank;

[0007] Using the blue and white colorant to draw a layout of exquisite eye patterns on the vase blank, and hollowing out and carving exquisite eyes based on the pattern layout to obtain an exquisite blank. Specifically, designing a desired exquisite eye pattern on the vase blank, drawing patterns on the designed exquisite eye pattern using the blue and white colorant to obtain a pattern layout, finally placing the drawn vase in a ventilated place to dry, and using a blank carving tool to carve exquisite eyes on the blank according to the designed pattern layout.

[0008] A layer of the glaze is evenly applied on the exquisite blank to cover the exquisite eyes and the pattern layout to obtain a glazed blank. Specifically, a glazing device is tested. After the glazing device is tested to be normal, the glaze is put into the glazing device for glazing preparation. The glazing of the glazing device's robot arm requires regular calibration and maintenance of the equipment. When applying the glaze, avoid applying too much or too little glaze to the same area.

[0009] Draw a firing curve, build a vase model for simulated firing, verify the firing curve and the firing parameters, and determine the firing conditions. Specifically, extract key parameters from the historical firing process from production records or databases, collect various parameters of the finished vase, and use professional drawing software to draw the firing curve; use time as the horizontal axis and temperature or other key parameters as the vertical axis to arrange the historical firing parameters in chronological order and draw a curve graph; finally, adjust the graph as needed, perform three-dimensional modeling of the glazed blank, and select appropriate simulation software for simulated firing based on the firing curve as a standard; set the temperature curve, heating rate, cooling rate, and atmosphere condition parameters of the simulated firing according to actual firing experience or experimental data; finally, import the vase model into the simulation software, set the simulation parameters, output the simulation results, simulate the firing again based on the firing curve and the firing parameters, compare and verify with the previous firing results, and analyze to determine the optimal firing conditions;

[0016] Designing a desired exquisite eye pattern on the vase blank, and decorating the exquisite eye pattern with the blue and white colorant to obtain a pattern layout;

[0017] Based on the pattern layout, a carving tool is used to hollow out and carve exquisite eyes on the vase blank to obtain an exquisite blank.

[0018] The specific method of uniformly applying a layer of the glaze on the exquisite blank to cover the exquisite eyes and the pattern layout to obtain the glazed blank is as follows:

[0019] Detecting the glazing equipment and putting the glaze into the glazing equipment to prepare the glaze;

[0020] The glazing equipment is used to evenly apply a layer of the glaze on the exquisite blank to cover the exquisite eyes and the pattern layout, thereby obtaining a glazed blank.

[0026] firing the glazed blank using a kiln based on the firing conditions, and naturally cooling the blank to obtain a fired blank;

[0027] The fired blank is polished again using a blank sharpening tool and cleaned to obtain a semi-finished vase;

[0028] Performing flaw detection on the semi-finished vases using flaw detection equipment to remove defective products;

[0029] The semi-finished vases after flaw detection are manually inspected, defective products are eliminated, and finished ceramic exquisite vases are obtained.

The glaze blank is fired, and the fired blank is pre-treated and quality-tested in sequence to obtain a finished ceramic exquisite vase. This method adds two steps to the traditional preparation process: simulated firing and quality testing. Based on the parameters of historical firing and fired finished products, the optimal firing temperature and time are simulated and tested, which can effectively avoid the occurrence of excessive or insufficient melting of the glaze. At the same time, defective products with defects such as internal cracks and gaps are eliminated through flaw detection. Finally, the appearance is manually inspected, thereby greatly improving the color and quality of the ceramic exquisite vase. This method solves the problem of excessive or insufficient melting of the glaze caused by lax temperature control in the existing ceramic exquisite vase color glaze decoration process.
