Description

Technical Field

[0001] This invention relates to the field of ceramic overglaze painting technology, and in particular to a ceramic overglaze color modifier and a ceramic overglaze splashing and engraving method. Background Technology

[0002] Ceramic decoration techniques can be divided into overglaze, inglaze, and underglaze. Overglaze is one of the main methods of ceramic decoration. It involves drawing various patterns on the glazed surface of a fired porcelain piece with various colored pigments, and then firing it a second time to solidify the pigments at a low temperature. Commonly used techniques include new color, famille rose, wucai (five-color), doucai (contrasting colors), famille verte, ink-painted gold-decorated porcelain, and enamel.

[0003] Through long-term practice, many rich ceramic decoration techniques have emerged, such as the new color splashing technique. However, when creating works using large-area splashes of pigment in new color decoration, the stability of conventional thinners (such as camphor oil) is very poor. The texture effect created immediately after splashing will be completely unrecognizable after a few minutes, making it difficult to create works using the immediate texture effect. This is because the "explosive" nature of the oil (large-area diffusion of the oil) will constantly cause the image to change, making it difficult to achieve the desired effect. Furthermore, the pigment dries slowly, affecting the efficiency of creation. In addition, traditional overglaze new color painting methods use brushes for outlining, shading, and coloring, but this can no longer meet the needs of more expressive forms, such as carving away pigments to depict objects. However, in current ceramic overglaze new color technology, because the pigment modifiers (mostly camphor oil and frankincense oil) adhere tightly to the porcelain surface after drying, it is impossible to remove excess pigment by carving, making it difficult to use carving techniques to depict the main image. Summary of the Invention

[0004] Therefore, based on the above background, this invention provides a ceramic overglaze color modifier and a ceramic overglaze splashing and engraving method, which solves the problems of instability and difficulty in controlling the splattering of new overglaze colors, blurring of the texture, and slow drying process of the pigments. It can quickly obtain complex textures and stabilize them without changing, and the pigments can dry quickly, providing favorable conditions for overglaze color creation. Furthermore, by combining splashing and engraving, large areas of pigment splashing can form clear, varied, and complex textures, allowing the use of a pen to freely engrave images on the porcelain surface, thus opening up new aesthetic fields and decorative forms in ceramic art.

[0005] Therefore, the present invention provides the following technical solution:

[0006] One objective of this invention is to provide a ceramic overglaze color modifier, said modifier being composed of the following raw materials in the indicated weight ratios:

[0007] Alcohol 80-95%, camphor oil 2-8%, frankincense oil 1-5%.

[0008] Preferably, the purity of the alcohol is 95%.

[0009] Preferably, the modifier is composed of the following raw materials in the indicated weight ratios:

[0010] Alcohol 92.6%, camphor oil 4.88%, frankincense oil 2.52%.

[0011] Based on the same technical concept, the present invention also provides a method for ceramic glaze splashing and engraving, which includes the following steps:

[0012] 1) Make the unglazed body, dry it, apply white glaze or celadon glaze or other colored glaze, and fire it at a high temperature of 1280-1300℃ to make a porcelain body;

[0013] 2) Modifying the colorant: Add the modifier to the new colorant powder and stir until it becomes a liquid;

[0014] 3) After the colorant is mixed, apply it to the porcelain surface by dripping or splashing it with a brush, allowing the colorant to flow freely;

[0015] Depending on the creative requirements, one or more colors can be dripped or splashed onto the porcelain surface. The pigments flow freely, and the colors will intermingle and permeate each other. The direction and speed of the pigment flow can be controlled by constantly rotating the angle and position to create rich and varied textures and color effects.

[0016] 4) After the pigments are applied according to the creative requirements, quickly apply a soft polyurethane foam to the entire image before the pigments dry to create a contrast between light and dark.

[0017] 5) After the pigment dries, use a needle pen to carve out the main image, remove the excess pigment, and expose the base color of the porcelain surface to form the image;

[0018] 6) After the entire image is engraved, spray an auxiliary flux onto the pigment as needed;

[0019] 7) Fire the ceramic at a low temperature of 810-825℃. After firing, cool it down.

[0020] Preferably, the weight ratio of the colorant to the modifier in step 2) is as follows:

[0021] Pigment powder: The modifier ratio is 18:82.

[0022] Preferably, the modifier is composed of the following raw materials in the indicated weight ratios:

[0023] Alcohol 92.6%, camphor oil 4.88%, frankincense oil 2.52%.

[0024] Preferably, the engraving method in step 5) can be one or more of line engraving or dot engraving.

[0025] Preferably, the needle pen used in step 5) can be one of a steel needle pen, a bamboo needle pen, or a wooden needle pen.

[0026] The advantages of this invention are:

[0027] This invention combines splashing and carving, allowing large-area splashing of color to create clear, varied, and complex textural effects. It also allows for free use of a pen to carve images on the porcelain surface, opening up new aesthetic realms and decorative forms in ceramic art. The modifier in this invention controls the oiliness and flaking properties of the colorants (large-area diffusion), thus preventing instability in the splashing process. This allows for control over the texture of the image and accelerates the drying speed of the colorants, quickly achieving a complex and stable textural effect. This creates favorable conditions for the creation of splashed-color overglaze paintings. Furthermore, the colorants prepared by the modifier have a loose and non-tight bond with the porcelain glaze, yet they adhere well to the surface, facilitating the removal of excess colorants using techniques such as line carving and dot carving, creating more flexible images. This innovative combination of splashing and carving on ceramic glaze allows for large-area splashing of color to create clear, varied, and complex textural effects, enabling free use of a pen to carve images on the porcelain surface, thus opening up new aesthetic realms and decorative forms in ceramic art.

[0028] Furthermore, this invention is applicable to both flat and three-dimensional ceramics, with wide application and simple operation. Because it is applied to the porcelain body and glaze, it avoids the drawbacks of underglaze painting, which is prone to breakage when applied to the clay body. It eliminates the need for additional glazing on the surface, resulting in a high success rate and rich color selection. This provides new methods and pathways for ceramic painting art creation, leading to new and unique art forms and styles. Attached Figure Description
