Detailed Description
The invention is further described below by means of specific embodiments.
The invention is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention easy to understand.
The archaizing glaze ceramic comprises a blank body and overglaze, wherein the outer surface of the blank body is covered with a pointed ornamental strip, and the ornamental strip comprises the following raw materials in parts by weight: 40-45 parts of kaolin, 25-30 parts of quartz, 15-20 parts of flint, 5-7 parts of bentonite and 4-5 parts of sodium sulfate, and the raw materials of the overglaze comprise the following components in parts by weight: 30-35 parts of quartz, 20-25 parts of celsian, 10-15 parts of wollastonite, 15-20 parts of porcelain clay, 3-4 parts of borax and 2-3 parts of zinc oxide. The surface glaze is a transparent glaze after being sintered; the decoration strip contains sodium sulfate, a smoking effect is formed on ceramic after firing, the blank surface is vitrified by the sodium sulfate in advance, so that the blank surface seals carbon particles in the early stage of firing in a reducing atmosphere, then the melted glaze prevents carbon from being discharged in the high-temperature stage of firing, meanwhile, the melting point of the sodium sulfate is lower, the sodium sulfate can be converted into partial sodium sulfide at a certain temperature, the melting point of the sodium sulfide is just in the strong reduction period of a product, the sodium sulfide is promoted to absorb carbon in the firing process of the product to form smoking marks similar to a firewood stove, the sodium sulfate has water solubility, and can be enriched on the surface of the decoration strip along with massive evaporation of water in the drying process of the decoration strip, and the existence of the sodium sulfate is a direct cause of smoking.
The raw materials of the green body comprise the following components in parts by weight: 35-40 parts of kaolin, 30-35 parts of quartz, 20-25 parts of flint, 5-8 parts of bentonite, 3-4 parts of sodium silicate and 3-4 parts of tannin extract. In grouting materials, in order to obtain slurry with low water content and good flowing property, a certain amount of electrolyte is added into a formula so as to dilute the slurry, such as sodium carbonate, sodium sulfate, sodium silicate and the like; if sodium carbonate is contained in the blank body in slip casting, the sodium carbonate reacts with gypsum to generate sodium sulfate, and the sodium sulfate can cause the blank body to yellow in the sintering process, so that the contents of the sodium sulfate and the sodium carbonate in the raw materials of the blank body are strictly controlled, sodium sulfate and sodium carbonate are not used as deflocculants, sodium silicate is used as deflocculants, and the sodium silicate does not react with calcium silicate in a mould to generate sodium sulfate, so that the blank body does not generate smoky yellow; meanwhile, tannin extracts are added into the blank to improve the surface activation performance of the blank, and the concentration of possible sulfate and sulfur dioxide in the blank is reduced, so that the smoking phenomenon is reduced; the blank body is enabled to present the natural color of the white porcelain after being fired through the configuration of the components, and phenomena of smoking and yellowing are avoided; the decorative strip is opposite to the green body, the sodium sulfate is actively configured to achieve the smoking effect, and as the decorative strip is sharp, the sodium sulfate is gathered at the edge and has higher concentration, so that the phenomenon of smoking yellowing is more obvious when the decorative strip is fired closer to the edge, the gradual smoking effect with gradually deepened color is presented, the decorative strip forms the effect similar to the effect of a fire mark of a firewood kiln, other green bodies present the white porcelain effect, and as the white porcelain is overall yellowing after firewood firing, the white porcelain cannot be fired through the firewood kiln, and the effect of local smoking of the local white porcelain cannot be presented; the process and the formula can combine two different effects of white porcelain and smoke fire mark effect innovatively, the whole has strong contrast and visual effect, the traditional cognition is overcome, the traditional defect of fire mark is converted into a special glaze effect, and the two different glaze effects are simultaneously displayed on one ceramic by respectively controlling the formulas and the preparation process in a green body and a decoration strip.
As a preferred embodiment: the decorative strip comprises the following raw materials in parts by weight: 42 parts of kaolin, 26 parts of quartz, 17 parts of flint, 6 parts of bentonite and 4.5 parts of sodium sulfate, and the raw materials of the overglaze comprise the following components in parts by weight: 32 parts of quartz, 22 parts of celsian, 12 parts of wollastonite, 17 parts of porcelain clay, 3.4 parts of borax and 2.5 parts of zinc oxide; the raw materials of the green body comprise the following components in parts by weight: 37 parts of kaolin, 32 parts of quartz, 22 parts of flint, 6 parts of bentonite, 3.4 parts of sodium silicate and 3.4 parts of tannin extract.
The section of the decorative strip is triangular, and the soluble salt is concentrated on the edge of the surface of the product along with the evaporation of water in the product drying stage, so that the higher the concentration of sodium sulfate is, the darker the color is, the lower the concentration of sodium sulfate is, the lighter the color is, the blank body is molded by grouting, and the decorative strip is molded by molding and is divided into two parts to mold the blank body, so that the pugs of two different components are compounded together.
The green body is an annular body, and the ornamental strip is annular. The annular decorative strip is coiled on the surface of the green body, the decorative strips are arranged on the green body at intervals from top to bottom, and the distribution forms of the decorative strips on the surface of the green body are various, and can be annular or vertical stripes.
The preparation method of the archaized glaze ceramic comprises the following steps:
step a, preparing a blank raw material and a decoration strip raw material; the green body raw material should reduce and inhibit the content of sodium sulfate or sodium carbonate as much as possible, while the raw material of the decoration strip is opposite, and the sodium sulfate with a certain proportion is controlled.
Step b, molding a blank by grouting, and then drying; because the content of sodium carbonate and sodium sulfate in the green body is very low, the phenomenon that sodium carbonate and gypsum react to generate sodium sulfate in the green body does not occur or does not occur very little.
Step c, adhering the mud of the decorative strip to the green body in a strip shape or a ring shape, and then drying; the raw material of the decoration strip is plastic pug, the pug is adhered to the green body after being kneaded into a strip shape with a triangular section, the components of the pug are the same as the raw material of the green body, and sodium sulfate is enriched on the surface of the decoration strip in the drying process.
Step e, applying overglaze on the green body and the decoration strip;
and f, sintering in a kiln. In the sintering process, the sodium sulfate on the surface of the decoration strip enables the green body to be vitrified in advance, so that the decoration strip is smoky yellow after sintering.
In the step a, kaolin, quartz, flint and bentonite in the blank raw material are crushed and ball-milled, then dehydrated by an overpressure filter, and then the slurry is re-slurried by adding water. After the ball-milled raw materials are dehydrated through filter pressing, soluble sulfate possibly contained in the raw materials can be filtered out in the dehydration process, so that the sulfate content in the raw materials is greatly reduced.
Adding water to reslurry, adding sodium silicate and tannin extract, and mixing to obtain the raw materials of the green body.
In the step c, before the decoration strip is adhered, firstly, an adhesive tape is adhered to the surface of the green body, a space for adhering the decoration strip is reserved between the adhesive tape and the adhesive tape, then the decoration strip is adhered to the surface of the green body between the adhesive tape and the adhesive tape, the surplus slurry in the gap between the adhesive tape and the decoration strip and the slurry on the surface of the adhesive tape are erased by a brush and a wet rag, and then the green body is dried in shade for 5-7 hours.
In the step c, after the adhesive tape on the surface of the green body is torn off after the green body is dried, the surface of the green body except the decorative strip is continuously wiped by a clean brush and a wet rag, and then the green body is dried. The steps are to prevent raw materials of the decorative strip from falling onto the green body and polluting the surface of the green body. In the invention, the decorative strip is positioned at a designated position, so that a smoking effect is formed at the designated position, and the effect of the glaze is displayed at other positions.
In the step f, the reducing atmosphere is maintained after the heating to 1000 ℃, the temperature is kept for 30 minutes, and then the temperature is raised to 1150 ℃ for sintering.
The foregoing is merely a few specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention by using the concept should be construed as infringement of the protection scope of the present invention.
