Description

【0001】
【発明の属する技術分野】
本発明は、食器、香炉、壺、照明器具用傘等の陶磁器類の形成方法に関する。
【0002】
【従来の技術】
従来、陶磁器類の装飾技法の一つとして、螢手が知られている。
螢手とは、半乾燥させて水分量を調整した成形体に透かし彫りを施し、かかる成形体を素焼きし、透孔に練土状の釉薬原料を埋め込んだ後、本焼成して、ガラス化した釉薬で閉じられた小窓(一般に、この小窓を螢手と称する場合もある。)を有する焼成品を得る様にした技法である。(例えば、非特許文献1参照)
又、素焼き後に透かし彫りを施す様にしたり、ディピング法を用い、釉薬泥漿の張力を利用して、素地全体に施釉すると同時に、釉薬泥漿の膜を透孔に形成し、透孔を釉薬原料で塞ぐ様にする場合もある。
ところが、強度の低い成形体に透かし彫りを施すためには、熟練した者による高度な技能が必要であったり、素地を用いて透かし彫りを施す様にしても、本焼成前に粘着力の乏しい釉薬原料で透孔を塞がなければならないことや、本焼成中に溶融した釉薬原料を透孔から脱落させずに融着させねばならないことから、透孔、即ち焼成品における螢手部分の径は数ミリが限度であるとされていた。

【発明が解決しようとする課題】
本発明は、従来の技法では限度とされていた数ミリ大の螢手の径をより大きなものにしたり、螢手周囲を形成しているセラミックス原料から成る部分を極力少なくし、螢手部分、即ちガラス化した釉薬を主体として骨格形成する様にした陶磁器類の形成方法を提供する。
【0005】
【課題を解決するための手段】
本発明は、上記従来技術に基づく、数ミリ大以上の径を有する螢手を形成することが困難な課題に鑑み、練土状釉薬原料と練土状セラミックス原料を交互に重ねて積層原料を形成し、次いで各原料層が切り口に露出する様に、前記積層原料を輪切りにして切断片を形成し、該切断片を複数並べ、各切断片の周縁を相互に結合させた後、全体を所定の形に整えることによって、螢手形成用透孔の穿設作業を不要にし、骨格の大部分が釉薬原料で構成されている成形体の形成を容易化すると共に、得られた成形体を前記釉薬原料の融点より低温で焼成し、焼結中釉薬の脱落を防止する様にして、上記課題を解決する。
【0006】
【発明の実施の形態】
以下本発明の一実施例を図面に基づいて説明する。
図1、2は第1実施例の形成方法の説明図、図3は当該方法によって形成された陶磁器類の斜視図である。
第1実施例の陶磁器類形成方法は、先ず水分量を加減して練土状に調整した釉薬原料1の形を棒状に整え、かかる棒状の釉薬原料1に、練土状に調整してシート状に圧延したセラミックス原料2を巻き付け、これを複数本束ねたものに、更にセラミックス原料2を巻き付けて、釉薬原料1とセラミックス原料2が交互に重ねられた積層原料3(図1(a)参照)を形成する。
次に、積層原料3中の各原料層が切り口に露出する様に、積層原料3を輪切りにして、切断片4、4a…(図1(b)参照)を形成し、該切断片4、4a…を平板上に複数個並べ、各切断片4、4a…の周縁を軽く押圧して、切断辺4、4a…を相互に結合させ、切断辺4、4a…を一体化させる(図2参照)。
最後に、一体化させた切断辺4、4a…を所望形状の成形型(例えば、椀状型)に押し付け、全体の形を整えて成形体5(図3参照)と成し、該成形体5を乾燥させた後、釉薬原料1の融点よりも低い温度で焼成して、焼成品6を得る。
【0007】
次に第2実施例の陶磁器類形成方法について説明する。
図4、5は第2実施例の陶磁器類形成方法の説明図、図6は図5のBーB断面図、図7は当該方法によって形成された陶磁器類の斜視図ある。
先ず、上記方法と同様に、釉薬原料1及びセラミックス原料2の水分量を加減して、夫々を練土状に調整する。
次に、釉薬原料1を平板状に圧延し(図4(a)参照)、かかる釉薬原料1の周縁をセラミックス原料2で縁取りして、額縁付原料7(図4(b)参照)を形成し、該額縁付原料7の裏面8側にセラミック原料2を貼付けて裏打ちをする(図5、6参照)。
この裏打ちは、焼成中に幾分軟化した釉薬原料1が脱落しない様にするためのもので、少なくとも釉薬原料1で形成された部分と、その周囲のセラミック原料2で形成された部分(額縁)の一部に施してあれば良く、本実施例のものでは、糸状に形成したセラミック原料2を裏面8の要部に格子状に貼付けている。
尚、糸状セラミック原料2の形成方法としては、例えば、袋の底に口金を付け、該袋にセラミック原料2を投入し、かかる袋を扱いて、袋の口金からセラミック原料2を押し出す様にすれば良い。
最後に、裏打ちした額縁付原料7を所望形状の成形型に押し付け、全体の形を整えて成形体9(図7参照)と成し、該成形体9を乾燥させた後、釉薬原料1の融点よりも低い温度で焼成して、焼成品10を得る。
【0008】
次に第3実施例の陶磁器類形成方法について説明する。
図8は第3実施例の方法で形成した陶磁器類の平面図であり、図9は図8のCーC断面図である。
先ず、スプレードライヤー等の適宜方法を用い、釉薬原料1及びセラミックス原料2を夫々顆粒状の坏土粉と成す。
次に、釉薬原料1の坏土粉を加圧成形用の型W内の所定位置に投入し、型W内のその他の位置には、セラミックス原料2の坏土粉を投入し、これを加圧し、得られた成形体11を乾燥させた後、前記釉薬原料の融点より低温で焼成して、焼成品12を得る。
【0009】
次に上記各実施例の方法に共通する事項について説明する。
上記各方法で用いたセラミック原料2は、窯炉が耐え得る温度下で焼結可能なものであれば良く、例えば、陶石、蝋石、長石、石灰、粘土、カオリン、珪石、アルミナ等の従前から用いられている一般的な窯業原料の中から、可塑性、耐火度等を考慮して、一種選択するか、二種以上選択し混合して用いれば良い。
【0010】
釉薬原料1は、セラミック原料2が焼結する温度で完全に溶融・液化してしまわず、且つ幾分融け、焼成によりセラミック原料2に融着し、焼成後に透光性を発現するものであれば、その組成、使用原料は何ら限定されない。
例えば、焼成温度、即ちセラミック原料2の焼結温度がゼーゲル式でSK8に相当する場合は、釉薬原料1の融点(完全に溶融・液化する温度)がゼーゲル式でSK9に相当する様に、釉薬原料1及びセラミック原料2の組成を調整すれば良い。
【0011】
釉薬原料1の可塑性、粘着力、加工性を向上させ、各成形体の形成をより容易なものとするために、釉薬原料1に適量のバインダーを添加するのが望ましく、バインダーとしては、珪酸ソーダ、CMC(カルボキシルメチルセルロース)のナトリウム塩、リグニン等が挙げられる。
バインダーの添加は、上記の様に、セラミック原料2の耐火度に応じて、釉薬原料1の組成を調整し、釉薬原料1の可塑性等が著しく低下してしまった場合に、特に有効である。
【0012】
尚、所望により、釉薬原料1及びセラミック原料2の何れか一方、又は両方に適宜組成の無機顔料を適量添加しても良い。
又、焼成品6、10、12の全体又は一部分に上塗り施釉し、再焼成しても良いが、再焼成温度は、焼成品6、10、12を形成した際の焼成温度より低く設定しなければならず、上塗り施釉に使用する釉薬の組成を、当該再焼成温度に応じて適切な溶融程度を示す様に調整しなければならない。
【0013】
次に釉薬原料及びセラミックス原料の水分量の調整について説明する。
図10、11は図2のAーA断面図であり、図10は焼成前の状態を示す図、図11は当該部分の焼成後の状態を示す図である。
釉薬原料1及びセラミックス原料2の水分量は、練土状に調整可能で、その後の加工が可能な状態になれば、両原料の水分量が同一か否かについて全く問わないが、釉薬原料1の水分量をセラミックス原料2の水分量より低くした場合、焼成時における釉薬原料1の収縮率がセラミックス原料2の収縮率より小さくなるため、図10に示す様に、焼成前において略同一であった釉薬原料1で形成された部分とセラミックス原料2で形成された部分の厚みは、その後の焼成によって、セラミックス原料2で形成された部分がより多く収縮し、その結果、図11に示す様な釉薬原料1部分のみが膨出した焼成品6と成る。
以上、各原料の水分量に関係し、第1実施例のものに基づき説明したが、第2、3実施例の方法においても、各原料の水分量を上記と同様に調整すれば、釉薬原料1で形成された部分のみが膨出した焼成品10、12が得られる。
【0014】
【発明の効果】
要するに本発明は、練土状釉薬原料1と練土状セラミックス原料2を交互に重ねて積層原料3を形成し、次いで各原料層が切り口に露出する様に、前記積層原料3を輪切りにして切断片4、4a…を形成し、該切断片4、4a…を複数並べ、各切断片4、4a…の周縁を相互に結合させた後、全体を所定の形に整え、得られた成形体5を前記釉薬原料1の融点より低温で焼成する様にしたので、ガラス化した釉薬で形成された部分の面積が広く、骨格の主体がガラス質の陶磁器類を形成することが出来、釉薬原料1に顔料を添加すれば、あたかもステンドグラスの様な陶磁器類を形成することが出来る。
【0015】
圧延した練土状釉薬原料1の周縁を練土状セラミックス原料2で縁取りして額縁付原料7を形成し、該額縁付原料7の裏面8側にセラミックス原料2を貼付けて裏打ちした後、全体を所定の形に整え、得られた成形体9を前記釉薬原料1の融点より低温で焼成する様にしたので、上記と同様なる効果を奏する他、裏打ちするセラミックス原料2の形状を適宜調整して、例えばセラミックス原料2で形成した細線で釉面上に様々な模様を描いて表情豊かな陶磁器類を形成することが出来る。
【0016】
型W内の所定位置に釉薬原料1粉を投入する一方、型W内のその他の位置にセラミックス原料2粉を投入し、しかる後加圧し、得られた成形体11を前記釉薬原料1の融点より低温で焼成する様にしたので、同一模様を有するステンドグラス様の陶磁器類を簡単に反復形成することが出来る。
【0017】
釉薬原料1にバインダーを添加する様にしたので、釉薬原料1の可塑性を向上させて、成形体5、9、11の形成を容易化することが出来ると共に、焼成前の形崩れを防止して、製品歩留りを向上させることが出来る。
【0018】
釉薬原料1の水分量をセラミックス原料2の水分量より低くする様にしたので、焼成時にセラミックス原料2で形成された部分を釉薬原料1で形成された部分より多く収縮させて、ガラス質部分が膨出した柔和な趣を有する陶磁器類を形成することが出来る等その実用的効果甚だ大である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for forming ceramics such as tableware, incense burners, pots, and umbrellas for lighting fixtures.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as one of the decoration techniques of ceramics, a fluorescent hand is known.
Fluorite is a semi-dried, moisture-adjusted molded body that is openwork carved, the molded body is unglazed, and a clay-like glaze material is embedded in the through-holes, followed by main firing and vitrification. This is a technique for obtaining a fired product having a small window closed with a glaze (generally, this small window may be referred to as a fluorescent lamp). (For example, see Non-Patent Document 1)
In addition, after unglazing, openwork can be applied, or the entire base can be glazed using the dipping method and the tension of the glaze slurry, and at the same time, a film of the glaze slurry can be formed in the through-holes, and the through-holes can be made of glaze material. In some cases, it may be closed.
However, in order to apply openwork to a low-strength molded body, advanced skills by a skilled person are required, or even when applying openwork using a base material, the adhesive strength is poor before firing. Since the through-hole must be closed with the glaze material and the glaze material melted during the main firing must be fused without falling off the through-hole, the diameter of the through-hole, that is, the diameter of the fluorescent part in the fired product Was said to be limited to a few millimeters.
[0003]
[Non-patent document 1]
Masataro Onishi, "Traditional Ceramic Techniques", Rigakusha, June 5, 1978, pp. 3-51-52.
[Problems to be solved by the invention]
The present invention is to increase the diameter of a few millimeters of fluorescent material, which has been limited by conventional techniques, or to minimize the portion of the ceramic material forming the periphery of the fluorescent material as much as possible. That is, the present invention provides a method for forming ceramics in which a skeleton is formed mainly by vitrified glaze.
[0005]
[Means for Solving the Problems]
The present invention has been made in view of the problem that it is difficult to form a fluorescent material having a diameter of several millimeters or more based on the above-described conventional technology. Forming, then, so that each raw material layer is exposed at the cut end, cut the laminated raw material into round pieces to form cut pieces, arrange the plurality of cut pieces, and bond the peripheral edges of each cut piece to each other. By shaping it into a predetermined shape, it is not necessary to drill through holes for forming fluorescers, and it is easy to form a molded body whose major part of the skeleton is composed of glaze raw material. The above problem is solved by firing at a temperature lower than the melting point of the glaze material to prevent the glaze from falling off during sintering.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
1 and 2 are explanatory views of the forming method of the first embodiment, and FIG. 3 is a perspective view of ceramics formed by the method.
In the method for forming ceramics of the first embodiment, first, the glaze raw material 1 adjusted to have a clay shape by adjusting the amount of water is adjusted to a rod shape, and the rod-shaped glaze raw material 1 is adjusted to a clay shape to form a sheet. A ceramic raw material 2 rolled into a shape is wound, and a plurality of the raw materials are bundled, and a ceramic raw material 2 is further wound thereon, and a laminated raw material 3 in which the glaze raw material 1 and the ceramic raw material 2 are alternately stacked (see FIG. 1A) ) Is formed.
Next, the laminated raw material 3 is cut into slices so that each raw material layer in the laminated raw material 3 is exposed at the cut end, and cut pieces 4, 4a,... (See FIG. 1B) are formed. 4a are arranged on a flat plate, and the edges of the cut pieces 4, 4a are lightly pressed to join the cut sides 4, 4a to each other, and the cut sides 4, 4a are integrated (FIG. 2). reference).
Finally, the integrated cut sides 4, 4a,... Are pressed against a mold having a desired shape (for example, a bowl-shaped mold), and the whole shape is adjusted to form a molded body 5 (see FIG. 3). After drying 5, it is fired at a temperature lower than the melting point of glaze raw material 1 to obtain fired product 6.
[0007]
Next, a method for forming ceramics of the second embodiment will be described.
4 and 5 are explanatory views of the method for forming ceramics according to the second embodiment, FIG. 6 is a sectional view taken along the line BB of FIG. 5, and FIG. 7 is a perspective view of the ceramics formed by the method.
First, similarly to the above method, the amount of water in the glaze raw material 1 and the ceramic raw material 2 is adjusted to make each of them into a clay.
Next, the glaze raw material 1 is rolled into a flat plate shape (see FIG. 4 (a)), and the periphery of the glaze raw material 1 is framed with the ceramic raw material 2 to form a framed raw material 7 (see FIG. 4 (b)). Then, the ceramic raw material 2 is adhered to the back surface 8 side of the framed raw material 7 and backed (see FIGS. 5 and 6).
This backing is to prevent the glaze raw material 1 somewhat softened during firing from falling off, and at least a part formed by the glaze raw material 1 and a part (frame) formed by the surrounding ceramic raw material 2 In this embodiment, the thread-shaped ceramic raw material 2 is stuck on the main part of the back surface 8 in a lattice shape.
As a method of forming the thread-like ceramic raw material 2, for example, a base is attached to the bottom of the bag, the ceramic raw material 2 is put into the bag, the bag is handled, and the ceramic raw material 2 is pushed out from the base of the bag. Good.
Finally, the lined framed raw material 7 is pressed against a molding die having a desired shape, and the whole shape is adjusted to form a molded body 9 (see FIG. 7). After drying the molded body 9, the glaze raw material 1 By firing at a temperature lower than the melting point, a fired product 10 is obtained.
[0008]
Next, a method for forming ceramics according to the third embodiment will be described.
FIG. 8 is a plan view of ceramics formed by the method of the third embodiment, and FIG. 9 is a sectional view taken along the line CC in FIG.
First, the glaze raw material 1 and the ceramic raw material 2 are each formed into a granular clay powder using an appropriate method such as a spray drier.
Next, the clay powder of the glaze raw material 1 is charged into a predetermined position in the mold W for pressure molding, and the clay powder of the ceramic raw material 2 is charged into other positions in the mold W, and this is added. After pressing, the obtained molded body 11 is dried and then fired at a temperature lower than the melting point of the glaze raw material to obtain a fired product 12.
[0009]
Next, items common to the methods of the above embodiments will be described.
The ceramic raw material 2 used in each of the above methods may be any material that can be sintered at a temperature that can be withstood by a kiln, for example, a conventional material such as pottery stone, rubble, feldspar, lime, clay, kaolin, silica stone, alumina and the like. From among the general ceramic materials used in the above, one kind may be selected or two or more kinds may be selected and mixed in consideration of plasticity, fire resistance and the like.
[0010]
The glaze raw material 1 does not completely melt and liquefy at the temperature at which the ceramic raw material 2 sinters, and also melts somewhat, fuses to the ceramic raw material 2 by firing, and develops translucency after firing. The composition and the raw materials used are not limited at all.
For example, when the sintering temperature, that is, the sintering temperature of the ceramic raw material 2 is a Zegel type and corresponds to SK8, the melting point of the glaze raw material 1 (the temperature at which it is completely melted and liquefied) is such that the glaze is equivalent to SK9 in the Zegel type. The compositions of the raw material 1 and the ceramic raw material 2 may be adjusted.
[0011]
In order to improve the plasticity, adhesion and workability of the glaze raw material 1 and to facilitate the formation of each molded body, it is desirable to add an appropriate amount of a binder to the glaze raw material 1, and the binder is sodium silicate. , CMC (carboxymethylcellulose) sodium salt, lignin and the like.
The addition of the binder is particularly effective when the composition of the glaze raw material 1 is adjusted according to the fire resistance of the ceramic raw material 2 and the plasticity of the glaze raw material 1 is significantly reduced as described above.
[0012]
If desired, an appropriate amount of an inorganic pigment having an appropriate composition may be added to one or both of the glaze raw material 1 and the ceramic raw material 2.
Further, the whole or a part of the baked products 6, 10 and 12 may be overcoated and re-baked, but the re-baking temperature must be set lower than the firing temperature when the baked products 6, 10 and 12 are formed. In addition, the composition of the glaze used for the top coat glaze must be adjusted to show an appropriate degree of melting according to the refiring temperature.
[0013]
Next, adjustment of the water content of the glaze raw material and the ceramic raw material will be described.
10 and 11 are sectional views taken along the line AA of FIG. 2, FIG. 10 is a diagram showing a state before firing, and FIG. 11 is a diagram showing a state of the portion after firing.
The water content of the glaze raw material 1 and the ceramic raw material 2 can be adjusted in the form of a clay, and if the subsequent processing is possible, it does not matter whether the water content of both raw materials is the same or not. When the water content of the ceramic raw material 2 is made lower than the water content of the ceramic raw material 2, the shrinkage rate of the glaze raw material 1 during firing becomes smaller than that of the ceramic raw material 2, so that as shown in FIG. The thickness of the portion formed of the glaze raw material 1 and the thickness of the portion formed of the ceramic raw material 2 are such that the portion formed of the ceramic raw material 2 shrinks more by subsequent firing, and as a result, as shown in FIG. Only one part of the glaze raw material becomes a baked product 6 which has swelled.
As described above, the description has been given based on the water content of each raw material based on that of the first embodiment. However, in the methods of the second and third embodiments, if the water content of each raw material is adjusted in the same manner as described above, the glaze raw material may be used. The fired products 10 and 12 in which only the portion formed in 1 swells are obtained.
[0014]
【The invention's effect】
In short, the present invention is to form a laminated raw material 3 by alternately laminating the raw clay glaze raw material 1 and the raw clay ceramic raw material 2, and then cut the laminated raw material 3 so that each raw material layer is exposed at the cut end. .. Are formed, a plurality of the cut pieces 4, 4a... Are arranged, and the peripheries of the respective cut pieces 4, 4a. Since the body 5 is fired at a temperature lower than the melting point of the glaze raw material 1, the area formed by the vitrified glaze is large, and the main body of the skeleton can form glassy ceramics. If a pigment is added to the raw material 1, ceramics such as stained glass can be formed.
[0015]
The periphery of the rolled clay-like glaze raw material 1 is framed with the clay-like ceramic raw material 2 to form a framed raw material 7, and the ceramic raw material 2 is attached and backed on the back surface 8 side of the framed raw material 7. Was formed into a predetermined shape, and the obtained molded body 9 was fired at a temperature lower than the melting point of the glaze raw material 1. Therefore, in addition to the same effects as above, the shape of the ceramic raw material 2 to be backed was appropriately adjusted. Thus, for example, various patterns can be drawn on the glaze surface with fine wires formed of the ceramic raw material 2 to form expressive ceramics.
[0016]
While one powder of the glaze raw material is placed at a predetermined position in the mold W, two powders of the ceramic raw material are placed at other positions in the mold W, and then the pressure is applied. Since the firing is performed at a lower temperature, stained glass-like ceramics having the same pattern can be easily and repeatedly formed.
[0017]
Since the binder is added to the glaze raw material 1, the plasticity of the glaze raw material 1 is improved, and the formation of the molded bodies 5, 9, and 11 can be facilitated, and the shape before firing is prevented from collapsing. , The product yield can be improved.
[0018]
Since the water content of the glaze raw material 1 was made lower than the water content of the ceramic raw material 2, the portion formed of the ceramic raw material 2 was shrunk more than the portion formed of the glaze raw material 1 during firing, and the vitreous portion was reduced. Its practical effect is extremely large, for example, it is possible to form a swollen and soft porcelain.
