[0012] The preparation process of the ceramic handicraft with reinforced body described above includes the following steps:

[0013] Step a: Prepare a high-temperature resistant skeleton;

[0014] Step b: Cover the high-temperature resistant frame with a wire mesh fabric;

[0015] Step c: Fabricate precast slabs;

[0016] Step d: Splice the precast panels onto the wire mesh fabric to form the outer blank layer, leaving grout injection ports on the outer blank layer, and then dry and shape it.

Detailed Implementation

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

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] This invention relates to a reinforced ceramic craft, comprising a high-temperature resistant skeleton, a wire mesh fabric, an inner body layer, and an outer body layer. The wire mesh fabric is fixed to the high-temperature resistant skeleton, the inner body layer is adhered to the inner side of the high-temperature skeleton and the wire mesh, and the outer body layer is adhered to the outer side of the high-temperature skeleton and the wire mesh. The outer body layer is composed of prefabricated panels with different patterns and colors spliced ​​together. The spliced ​​prefabricated panels lack sufficient support strength, thus requiring reinforcement through the high-temperature resistant skeleton and the inner body layer. The prefabricated panels are fired first and then spliced ​​together, thus eliminating the need for additional glazing after the body is formed. The joints of the prefabricated panels form a geometric texture with clear boundaries. Larger seams are filled with slurry, creating a distressed and antique aesthetic. After firing, the overall piece possesses a unique artistic beauty. The high-temperature resistant skeleton, acting as the framework for the spliced ​​outer body layer, provides excellent reinforcement and support. The inner body layer and the wire mesh fabric, made of the same material as the outer body layer, are adhered to the inner side of the outer body layer, further enhancing its strength and ensuring that the body is less prone to cracking during firing.

[0029] The high-temperature resistant skeleton is made of high-temperature resistant metal wire. The preferred material for the high-temperature resistant metal wire is nickel-chromium alloy, with a diameter of 0.6-1.2 mm. High-temperature resistant skeletons made of nickel-chromium alloy have good high-temperature resistance and can maintain sufficient strength at high temperatures.

[0030] At the intersection of the high-temperature resistant skeleton, inward and outward metal hooks are formed. The inward extension of the metal hooks is used to improve the adhesion with the inner blank layer, and the outward extension is used to improve the adhesion with the outer blank layer. The outward metal hooks are exposed on the surface of the outer blank layer, which has an industrial aesthetic of splicing metal and ceramic.

[0031] The surface of the high-temperature resistant skeleton is covered with a bottom layer of protective mud, a middle layer of protective mud, and a transparent glaze from the inside out.

[0032] The raw materials for the bottom protective mud, by weight, include the following components: 20-25 parts clay, 8-12 parts quartz powder, 15-18 parts calcined kaolin, 8-10 parts montmorillonite, 4-5 parts illite, 6-8 parts pyrophyllite powder, and 4-6 parts flannel fiber; the raw materials for the middle protective mud, by weight, include the following components: 22-26 parts clay, 10-12 parts quartz powder, 16-18 parts calcined kaolin, 7-10 parts montmorillonite, 2-3 parts copper oxide, and 2-3 parts silicon carbide; the raw materials for the transparent glaze, by weight, include the following components: 25-28 parts calcined kaolin, 20-22 parts potassium feldspar, 10-12 parts calcite, 12-14 parts sodium feldspar, 7-10 parts calcined talc, 2-3 parts zinc oxide, 5-7 parts quartz, and 2-3 parts barium carbonate. The mineral raw materials in the bottom protective slurry, the middle protective slurry, and the transparent glaze are all sieved through a 200-mesh screen to ensure the fine texture of the raw materials. This effectively reduces the shrinkage rate of the protective slurry and the transparent glaze. The flannel fibers in the bottom protective slurry help improve the adhesion of the slurry, allowing it to better adhere to the metal wire. The copper oxide in the middle protective slurry colors the high-temperature resistant skeleton, making the exposed parts of the high-temperature resistant skeleton appear black. The high-temperature resistant skeleton is protected by two layers of slurry and one layer of transparent glaze, which can further improve its high-temperature resistance, reduce the phenomenon of high-temperature melting of the skeleton, and also improve the bonding strength with the inner and outer blanks.

[0033] The outer blank layer is made of precast slabs spliced ​​together.

[0034] The precast slab is characterized by comprising, from bottom to top, a base layer and a color paste layer. The base layer is made of paper clay slurry, and the color paste layer comprises, by weight, the following components: 90-95 parts paper clay slurry and 3-5 parts colorant. The inner layer comprises, by weight, the following components: 90-95 parts paper clay slurry and 3-5 parts carboxymethyl cellulose gum. Different colors of colorant are added to the color paste layer of different precast slabs, resulting in precast slabs displaying different colors such as yellow, green, red, white, and black. The artworks made by splicing together precast slabs of different colors have a striking contrast, and coupled with the different decorative patterns, they possess a unique artistic aesthetic.

[0035] The raw materials for paper clay slurry, by weight, include the following components: 65-70 parts kaolin, 20-24 parts feldspar, 5-6 parts limestone, 6-8 parts porcelain stone powder, 15-16 parts talc, 2-3 parts starch, 2-3 parts flour, 6-8 parts pulp, and 3-4 parts glycerin. The addition of starch, flour, pulp, and glycerin to the paper clay gives it high strength, good plasticity, light weight after firing, resistance to cracking, and fast drying. When used in the inner layer of the paper, it can quickly form the inner layer and improve the overall strength of the paper body.

[0036] The preparation process of the ceramic handicraft with reinforced body described above includes the following steps:

[0037] Step a: Prepare a high-temperature resistant skeleton;

[0038] Step b: Cover the high-temperature resistant skeleton with a wire mesh fabric; the raw material of the wire mesh fabric is a flexible material such as viscose fiber; the wire mesh fabric is attached to the high-temperature resistant skeleton and serves as a connecting layer between the inner and outer blank layers, making the bonding between the inner and outer blank layers stronger. During the forming and drying stages, the blank is not easy to fall off, and during the firing stage, the wire mesh fabric decomposes at high temperature.

[0039] Step c: Fabricate precast slabs;

[0040] Step d: Splice the precast panels onto the wire mesh fabric to form the outer blank layer, leaving grout injection ports on the outer blank layer, and then dry and shape it; during the splicing process, use a hammer, carving knife, etc. to cut to the appropriate size, and use paper clay grout to bond and fill the joints of the precast splices. The outward metal hooks are exposed from the joints of the precast panels, and the gaps between the metal hooks and the precast panels are filled with paper clay grout.

[0041] Step e: Inject paper clay slurry into the inner layer through the slurry inlet of the outer layer. The paper clay slurry adheres to the inner side of the screen fabric, forming the inner layer. Carboxymethyl cellulose gum is added to the paper clay slurry of the inner layer. The carboxymethyl cellulose gum improves the viscosity and adhesion of the paper clay slurry, thereby increasing the forming speed of the inner layer. The raw materials of the precast board contain pulp fibers and other organic matter. After bisque firing, its porosity is high. Therefore, when the paper clay slurry is injected into the inner layer of the outer layer and dried simultaneously, a humidity diffusion gradient is formed from the inside to the outside. The paper clay slurry gradually adheres to the inner side of the screen fabric, and the inner layer and the outer layer combine with each other, which can improve the bonding strength of the outer layer that is spliced ​​by the precast board. The paper clay slurry has an accumulation effect near the metal hooks of the high-temperature resistant skeleton, which can improve the adhesion between the inner layer and the high-temperature resistant skeleton.

[0042] Step f: The ceramic body is fired in a kiln. The firing temperature is 1150-1200 degrees Celsius, and the holding time is 30 minutes. During the high-temperature firing process, a small portion of the high-temperature resistant skeleton will melt, but most of the skeleton can maintain its strength, making the ceramic body less prone to cracking. After firing, the outer surface of the ceramic craft is made up of pieces decorated with different patterns and colors, and its surface also exposes black metal hooks, which has a unique artistic beauty. Through the above specific preparation process, ceramic crafts with reinforced bodies and splicing effects are produced.

[0043] In step a, high-temperature resistant metal wires are bent, cut and crossed to build a high-temperature resistant skeleton. The intersection of the high-temperature resistant skeleton forms inward and outward metal hooks. The surface of the high-temperature resistant skeleton is coated with a base protective mud, a middle protective mud and a transparent glaze in sequence. After each layer is coated, it is dried with hot air before the next layer is coated. Then it is placed in a kiln and bisque fired at 800-900 degrees Celsius.

[0044] In step b, the wire mesh fabric is fixed to the high-temperature resistant frame and metal hooks;

[0045] In step c, the preparation method of the precast slab is as follows: pour the base material into the plaster mold, dry it, pour in the color paste layer material, dry it, peel it off from the plaster mold, carve patterns and paint on the precast slab, and then put it into the kiln for bisque firing.

[0046] In step d, a layer of adhesive for bonding with the screen fabric is brushed onto the back of the precast panel, and the joints of the precast panels are bonded with paper clay paste.

[0047] In step e, clamp the metal hooks of the high-temperature resistant skeleton outward with a clamp and fix the clamp to the rotating bracket. After injecting paper clay slurry into the slurry inlet, plug the slurry inlet with a silicone plug. Rotate the blank and the bracket together along two mutually perpendicular rotating axes while drying. Then open the slurry inlet to discharge excess slurry. Repeat this process 4-5 times to form an inner blank layer on the screen fabric. After opening the slurry inlet, continue drying for 4-5 hours.

[0048] In step f, the firing temperature is 1150-1200 degrees Celsius, and the holding time is 30 minutes.

[0049] The above are merely some specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
