Description

Technical Field

[0001] The present invention relates to the field of ceramics and preparation methods thereof, in particular to a ceramic handicraft with a colorful laminated reinforced body and a preparation method thereof. Background Art

[0002] Colored glaze, also known as overglaze (such as five-color and pastel), is a ceramic coloring technique in which patterns and colors are painted on the glaze surface of the fired porcelain, and then fired in a red kiln at a low temperature of approximately 700-800°C. Furthermore, painting on the base body before firing, such as in blue and white porcelain and underglaze red, is called colored glaze. Its characteristic is that the color is trapped under the high-temperature glaze and never fades. Traditional overglaze glazes achieve a colorful glaze effect by painting different textures in different locations on the base body. However, the decorative textures are all on the surface of the base body, lacking a rich sense of layering and depth. In view of this, this project was created. Summary of the Invention

DETAILED DESCRIPTION

[0026] The present invention is further described below through specific embodiments.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] The present invention discloses a ceramic craft with a colorful laminated reinforced body, comprising a body, a glaze, and a supporting frame. The body is formed by enclosing a composite clay board, the supporting frame being disposed within the body, the composite clay board being pressed from multiple clay boards with decorative patterns, the thickness of a single layer of clay board being controlled at 0.5-1 mm, the number of clay board layers of the composite clay board being 2-4, and the clay board being not too thick to ensure a certain degree of light transmittance. The body formed by pressing multiple clay boards with decorative patterns has a colorful pattern after firing. The body is supported by the supporting frame, which not only strengthens the body and facilitates shaping and repairing of the body, but also reduces deformation during firing and serves as a decoration for the ceramic. Unlike traditional overglaze colors, the colorful pattern is presented through multiple layers of clay boards, and has a rich sense of layering and depth.

[0029] The raw materials for the clay board, by weight, include the following: 35-40 parts clay, 25-30 parts feldspar, 22-25 parts quartz, 4-8 parts limestone, 5-8 parts glass fiber, and 4-6 parts carboxymethyl cellulose glue. The high proportion of quartz in the original clay board contributes to its excellent light transmittance. The top glaze is a translucent matte glaze, made from the following raw materials, by weight: 40-45 parts nepheline orthoclase, 20-30 parts silica, 20-30 parts borate, 18-22 parts kaolin, 8-10 parts wollastonite, 4-8 parts bentonite, and 2-3 parts rutile. The glass fiber and carboxymethyl cellulose glue enhance the clay board's strength during the forming and drying stages, facilitating plasticization.

[0030] Decorative patterns are painted on the surface of the clay tablet using pattern colorants, and decorative patterns of the same or different colors are painted on different layers of the composite clay tablet.

[0031] The raw materials of the pattern colorant include but are not limited to the following formula:

[0032] 1. The raw materials of the pattern colorant, calculated by weight, include the following components: 25-30 parts borate, 20-25 parts silicon dioxide, 30-35 parts kaolin, 20-25 parts talc, 12-15 parts calcium carbonate, 4-8 parts zinc oxide, and 10-12 parts red iron oxide. The pattern colorant appears black.

[0033] The raw materials of the pattern colorant, calculated by weight, include the following components: 25-30 parts borate, 20-25 parts silicon dioxide, 30-35 parts kaolin, 20-25 parts talc, 12-15 parts calcium carbonate, 4-8 parts zinc oxide, 2-3 parts copper carbonate, 2-3 parts cobalt carbonate, and 2-3 parts rutile. The pattern colorant exhibits a blue color.

[0034] 2. The raw materials of the pattern colorant, calculated by weight, include the following components: 25-30 parts borate, 20-25 parts silicon dioxide, 30-35 parts kaolin, 12-15 parts fluorite, 14-18 parts potassium dichromate, and 5-8 parts calcium chloride. This pattern colorant exhibits a green color. In the present invention, pattern colorants include, but are not limited to, the three colors mentioned above. By combining colorants of different colors, a variety of color combinations can be created.

[0035] 3. The joints where the composite mud panels are enclosed are fixed with screws.

[0036] The top and / or bottom of the support frame are exposed outside the body. The surface of the support frame is covered with a protective agent composed, by weight, of the following ingredients: 20-30 parts silica, 20-30 parts kaolin, 15-20 parts wollastonite, and 5-6 parts rutile. The protective agent adheres to the surface of the support frame and, after firing, forms a black protective layer. This layer protects the support frame and reduces deformation and melting at high temperatures. The exposed black frame creates a strong contrast with the colorful glaze, resulting in a unique artistic aesthetic.

[0037] The method for preparing the ceramic handicraft having a colorful laminated reinforced body comprises the following steps:

[0038] Step a, preparing a supporting frame;

[0039] Step b, preparing a clay board, and coloring the surface of each layer of the clay board;

[0040] Step c, stacking and pressing multiple clay boards together to obtain a composite clay board;

[0041] Step d: Wrap the composite mud board around the support frame; the support frame serves as a support for the composite mud board, that is, it supports and strengthens the blank. When the support frame extends beyond the blank, it also serves as a decoration.

[0042] Step e, fixing the joints of the composite mud board, and shaping and trimming the blank;

[0043] Step f, the green body is placed in a kiln for biscuit firing at a temperature of 800-900 degrees Celsius;

[0044] Step g: applying glaze on the surface of the blank; the glaze is a translucent matte glaze that matches the color of the blank. When the blank is illuminated by light inside, the blank emits soft colorful light spots.

[0045] Step h: putting the ceramic into a kiln for glaze firing to obtain a ceramic product, the glaze firing temperature being 1200-1250 degrees Celsius.

[0046] In step a, the support frame is made of metal wire by cutting, bending and splicing. After the support frame is made, a protective agent is brushed on its surface; the protective agent can provide a certain degree of protection for the support frame, but partial melting and deformation of the support frame at high temperature is acceptable, and it will have a unique aesthetic.

[0047] In step b, coloring is performed on the same or different heights on each layer of the clay plate, and pattern colorants of the same or different colors are drawn on clay plates of different layers; the pattern decoration can be located at different heights on the clay plate, and pattern decoration of different colors is used. The multiple layers of clay plates are superimposed and pressed, and combined with the glaze on the surface, different colors are presented at different heights after firing. The whole is a colored translucent ceramic. If the composite clay plate is rolled into a long tube, it becomes a lamp with colorful patterns. When a light source is placed inside, the light passes through the lamp wall to form colorful patterns with unique beauty. The patterns on clay plates of different layers can also overlap, and the overlapping parts will form new colors.

[0048] In step c, the surface of the composite clay board is sprayed with water, clay strips or balls of a different color than the composite clay board are placed on the surface of the composite clay board, covered with newspaper, and then pressed with a metal block. Then, a wooden pole is used to repeatedly roll and press the clay strips or balls into the clay board. Finally, the edges of the composite clay board are trimmed to the desired size. Multiple clay boards are stacked on top of each other, and glass fiber is added to effectively strengthen the blank. The clay strips or clay boards on the surface of the composite clay board naturally increase and deform during the rolling and pressing process, creating a natural textured decorative effect.

[0049] In step e, the composite panels are secured with screws. The screws are screwed into the joints to secure the two overlapping panels. After firing, the screws partially melt and fuse with the ceramic, leaving exposed screw heads on the glaze, creating a unique industrial aesthetic.

[0050] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
