Abstract
Description
本発明は、曜変模様によって加飾される陶磁器の曜変加飾方法並びにその製造方法に関する。 The present invention relates to a method for producing a day change of a ceramic decorated with a day change pattern and a method for producing the same.
従来、陶磁器表面において曜変加飾を施す方法としては、例えば特許文献１の開示技術が提案されている。 Conventionally, for example, a technique disclosed in Patent Document 1 has been proposed as a method for performing day-decorating decoration on a ceramic surface.
この特許文献１の開示技術では、鉛と銀とを含む曜変核形成剤を準備し、この曜変核形成剤を天目釉茶碗の釉薬表面に部分的に付着させ、これを還元焼成する。これにより、黒ないし灰色のガラス状に溶融した斑点状の曜変核形成剤の塗布部分の外周辺には、水色から紺色に発色したグラデーション模様が拡散して発現することになる。そしてこのグラデーション模様は、金色あるいは虹色に彩られ、光の当たり具合によってそれら光彩が変化するところの曜変紋様として焼き付けられることになる。
しかしながら、上記特許文献１の開示技術では、人為的に曜変核形成剤を付着させる工程が入ることから、曜変加飾を実行する上で労力の負担が過大となり、量産する上で大きな障壁となるという問題点があった。また、人為的に曜変核形成剤を付着させる必要が生じるこの特許文献１の開示技術では、得られる曜変模様そのものが人工的であることが視覚的にどうしても現れてしまうことは否めず、より自然な模様を醸し出すことができないという問題点があった。 However, since the disclosed technique disclosed in Patent Document 1 involves a step of artificially attaching a day-changing nucleating agent, the burden of labor is excessive when performing day-changing decoration, which is a great barrier to mass production. There was a problem. Further, in the disclosed technique of Patent Document 1 in which it is necessary to artificially attach a day-changing nucleating agent, it cannot be denied that the obtained day-changing pattern itself is artificially visible, and more natural. There was a problem that it was not possible to create a unique pattern.
そこで本発明は、上述した問題点に鑑みて案出されたものであり、その目的とするところは、人為的に曜変核形成剤を付着させる工程を設けることなく、これを自然に醸し出すことが可能な曜変加飾方法並びにその製造方法を提供することにある。 Therefore, the present invention has been devised in view of the above-mentioned problems, and the object of the present invention is to naturally bring it out without providing a step of artificially attaching a day-changing nucleating agent. An object of the present invention is to provide a possible day changing decoration method and a manufacturing method thereof.
本発明を適用した陶磁器の曜変加飾方法は、上述した課題を解決するために、表面に釉薬を予め塗布した成形体を９００℃以上まで焼成し、上記成形体の焼成時において少なくとも成形体表面に炭素が付着する程度まで過剰に炭素を供給し、上記成形体表面に付着させた炭素に基づいて上記釉薬を強還元させるとともに、当該炭素自身が炭素膜として焼き付けられることにより、成形体表面に曜変模様を加飾させることを特徴とする。 In order to solve the above-mentioned problems, the method for decorating a ceramic day by applying the present invention baked a molded body in which a glaze has been applied in advance to 900 ° C. or higher, and at least the surface of the molded body during firing of the molded body. The carbon is excessively supplied to the extent that carbon adheres to the surface of the molded body, and the glaze is strongly reduced based on the carbon deposited on the surface of the molded body. It is characterized by decorating day-changing patterns.
また、本発明を適用した曜変加飾陶磁器の製造方法は、上述した課題を解決するために、表面に釉薬を予め塗布した成形体を９００℃以上まで焼成し、上記成形体の焼成時において少なくとも成形体表面に炭素が付着する程度まで過剰に炭素を供給し、上記成形体表面に付着させた炭素に基づいて上記釉薬を強還元させるとともに、当該炭素自身が炭素膜として焼き付けられることにより、成形体表面に曜変模様を加飾させた曜変加飾陶磁器を製造することを特徴とする。 Further, in order to solve the above-described problems, the method for producing a day-decorated ceramics to which the present invention is applied baked a molded body in which glaze has been applied in advance to 900 ° C. or higher, and at least when the molded body is baked. The carbon is excessively supplied to the extent that carbon adheres to the surface of the molded body, and the glaze is strongly reduced based on the carbon adhered to the surface of the molded body, and the carbon itself is baked as a carbon film, thereby forming the molding. It is characterized by producing a day-decorated ceramic with a body-decorating pattern on the body surface.
上述した構成からなる本発明によれば、焼成時において、少なくとも成形体表面に炭素が付着する程度まで過剰に炭素を供給する。過剰に供給された炭素は、煤として成形体表面に付着し、この付着した炭素周囲の釉薬が強還元されて光彩を発するようになる。煤を基にした炭素は、自然の状態では、群や斑点を形成するようにして成形体表面に付着するが、場合によっては、成形体の全面に亘って付着する。そして、この焼成温度の最高点から徐々に温度を下げ始めると、この煤として成形体表面に付着した炭素自身が炭素膜として焼き付けられることになる。ちなみにこの形成された炭素膜も同様に光彩を放つようになる。 According to the present invention having the above-described configuration, at the time of firing, excessive carbon is supplied to the extent that carbon adheres to at least the surface of the molded body. The excessively supplied carbon adheres to the surface of the molded body as soot, and the glaze around the attached carbon is strongly reduced to emit a glow. Carbon based on soot adheres to the surface of the molded body in a natural state so as to form groups and spots, but in some cases, it adheres over the entire surface of the molded body. Then, when the temperature is gradually lowered from the highest point of the firing temperature, the carbon itself adhering to the surface of the molded body as this soot is baked as a carbon film. By the way, this formed carbon film also emits radiance.
その結果、本発明では、人為的に曜変核形成剤を付着させる工程が入らないことから、曜変模様が人工的ではなく、より自然に形成され、曜変加飾を実行する上で労力の負担を軽減させることができ、量産化により適した方法とすることが可能となる。 As a result, in the present invention, since the step of artificially attaching the day-changing nucleating agent does not enter, the day-changing pattern is not artificial, is formed more naturally, and the burden of labor is required in performing day-of-day decoration. It can be reduced, and a method more suitable for mass production can be obtained.
以下、本発明を実施するための最良の形態として、曜変模様によって加飾される陶磁器の曜変加飾方法について、図面を参照しながら詳細に説明する。 Hereinafter, as a best mode for carrying out the present invention, a method for decorating the day of a ceramic decorated with a day-changing pattern will be described in detail with reference to the drawings.
本発明による曜変模様の加飾対象としての成形体は、表面に釉薬を予め塗布されたものである。成形体は、粘土により手づくね、巻上、輪積み、塗型、打ち出し成形、ろくろ成形、押型等で成形されたものである。また塗布される釉薬は、鉄釉（燐酸分、チタン分、鉄分が含まれている釉薬）を想定しているが、必ずしも鉄を発色剤として含む天目釉系の黒色釉に限るものではなく、通常の無色の長石系釉薬、銅を発色剤として含む織部調の緑釉、コバルトを発色剤とした瑠璃色釉など、各種の発色顔料で着色した多くの低火度釉および高火度釉を用いるようにしてもよい。 The molded object as a decoration object of the day change pattern by this invention applies a glaze beforehand to the surface. The molded body is formed by clay, rolling, rolling, coating, punching, potting, stamping, or the like. In addition, the glaze to be applied is assumed to be iron glaze (glaze containing phosphoric acid, titanium content, iron content), but is not necessarily limited to the Tenmoku black glaze containing iron as a color former, Many low- and high-temperature glazes colored with various coloring pigments, such as ordinary colorless feldspar-based glazes, woven green tones containing copper as a color former, and amber-colored glazes using cobalt as a color former You may make it use.
本発明によれば、これらの釉薬の本来の発色を示す釉層上に本発明の曜変紋様が斑紋として重なり合って発現されるため、それぞれの発色が混合した個性的な色紋様を奏することになる。 According to the present invention, since the daily variation pattern of the present invention is expressed as a mottled pattern on the cocoon layer showing the original color of these glazes, a distinctive color pattern with a mixture of the respective colors is produced. .
次に、このような釉薬が予め表面に塗布された成形体を、例えば図１に示すような窯１の中に入れる。窯１は、厚肉耐火レンガからなる周壁１１及び天井壁１５により形成された焼成室１２と、周壁１１に取り付けられたガスバーナー１３と、焼成室１２内の空気を窯外へ排出するための排気口としての役割を担う煙突１４とを備えている。ちなみに、この窯１は、成形体の出し入れを容易に実行可能とするために、図示しない台車が進退自在に配設されていてもよい。 Next, the molded body in which such a glaze has been applied to the surface in advance is placed in a kiln 1 as shown in FIG. The kiln 1 is for firing the firing chamber 12 formed by the peripheral wall 11 and the ceiling wall 15 made of thick refractory bricks, the gas burner 13 attached to the peripheral wall 11, and discharging the air in the firing chamber 12 to the outside of the kiln. A chimney 14 serving as an exhaust port is provided. Incidentally, in the kiln 1, a cart (not shown) may be disposed so as to be able to advance and retreat in order to make it possible to easily carry out and take out the molded body.
窯１における焼成室１２内に成形体を設置した後、その成形体の焼成を行う。この成形体の焼成は、ガスバーナー１３による加熱により行うが、これに限定されるものではなく、灯油による加熱を併用してもよいし、またガスバーナー１３の代替として灯油のみを用いて加熱するようにしてもよい。 After the molded body is placed in the firing chamber 12 of the kiln 1, the molded body is fired. The firing of the molded body is performed by heating with the gas burner 13, but is not limited to this. Heating with kerosene may be used in combination, or heating with kerosene alone as an alternative to the gas burner 13. You may do it.
焼成温度は、９００℃以上で行う。焼成温度の下限を９００℃とした理由は、９００℃未満では本発明所期の強還元が生じないためである。ちなみに、この焼成温度９００℃に至るまでの加熱速度はいかなるものであってもよい。また、焼成温度の上限は特に規定しないが、１３００℃程度を上限とすることが望ましい。その理由として、焼成温度が１３００℃を超えると、窯１の損傷につながる場合もあるためである。 The baking temperature is 900 ° C. or higher. The reason why the lower limit of the firing temperature is set to 900 ° C. is that if the temperature is less than 900 ° C., the strong reduction as expected in the present invention does not occur. Incidentally, any heating rate up to the firing temperature of 900 ° C. may be used. The upper limit of the firing temperature is not particularly specified, but it is desirable that the upper limit is about 1300 ° C. This is because if the firing temperature exceeds 1300 ° C., the kiln 1 may be damaged.
本発明では、この焼成時において、少なくとも成形体表面に炭素が付着する程度まで過剰に炭素を供給する。過剰に炭素を供給する方法としては、いかなる方法を用いてもよいが、例えばガスバーナー１３や灯油により窯焚きを実行するとともに、煙突１４の排気口を狭幅化させ又はほぼ閉塞することにより、窯内に炭素を充満させるようにしてもよい。これにより排出量を超えた過剰な炭素分を窯内に残存させることが可能となる。 In the present invention, at the time of firing, the carbon is supplied excessively to the extent that carbon adheres to at least the surface of the molded body. Any method may be used as a method of supplying excess carbon. For example, by performing kiln burning with a gas burner 13 or kerosene, by narrowing or substantially closing the exhaust port of the chimney 14, The kiln may be filled with carbon. Thereby, it becomes possible to leave an excessive carbon content exceeding the discharge amount in the kiln.
過剰に供給された炭素は、煤として成形体表面に付着し、この付着した炭素周囲の釉薬が強還元されて光彩を発するようになり、瑠璃色、青色、緑色、赤色、黄色等の光の干渉による虹色を発する場合もある。実際にその強還元により発する色合いは下地に使用されている釉薬の色彩や成分により支配される。この煤を基にした炭素は、自然の状態では、群や斑点を形成するようにして成形体表面に付着するが、場合によっては、成形体の全面に亘って付着する。そして、この焼成温度の最高点から徐々に温度を下げ始めると、この煤として成形体表面に付着した炭素自身が炭素膜として焼き付けられることになる。ちなみにこの形成された炭素膜も同様に光彩を放つようになる。 The excessively supplied carbon adheres to the surface of the molded body as soot, and the glaze around the attached carbon is strongly reduced to emit a glow, and light such as amber, blue, green, red, yellow is emitted. There may be a rainbow color due to interference. Actually, the hue generated by the strong reduction is governed by the color and components of the glaze used for the base. The carbon based on the soot adheres to the surface of the molded body in a natural state so as to form groups and spots, but in some cases, it adheres to the entire surface of the molded body. Then, when the temperature is gradually lowered from the highest point of the firing temperature, the carbon itself adhering to the surface of the molded body as this soot is baked as a carbon film. By the way, this formed carbon film also emits radiance.
なお、この形成された炭素膜は比較的短時間に亘り、高温度で還元状態が途切れると、黄白色の炭素膜となって表面に付着する場合もある。 The formed carbon film may be attached to the surface as a yellowish white carbon film when the reduced state is interrupted at a high temperature for a relatively short time.
このように、本発明を適用した陶磁器の曜変加飾方法では、表面に釉薬を予め塗布した成形体を９００℃以上まで焼成し、成形体の焼成時において少なくとも成形体表面に炭素が付着する程度まで過剰に炭素を供給し、成形体表面に付着させた炭素に基づいて釉薬を強還元させるとともに、当該炭素自身が炭素膜として焼き付けられることにより、成形体表面に曜変模様を加飾させることができる。 As described above, in the method for decorating ceramics using the present invention, the molded body in which the glaze is preliminarily applied to the surface is fired to 900 ° C. or more, and at least the carbon adheres to the surface of the molded body when the molded body is fired. In addition to excessively supplying carbon, the glaze is strongly reduced based on the carbon adhered to the surface of the molded body, and the carbon itself is baked as a carbon film, thereby decorating the surface of the molded body with a diurnal pattern. it can.
図２、３は、本発明を適用した陶磁器の曜変加飾方法により実際に曜変模様を施した陶磁器の例を示している。 FIGS. 2 and 3 show examples of ceramics that are actually given a day-changing pattern by a method for decorating ceramics to which the present invention is applied.
図２、３から分かるように、本発明では、人為的に曜変核形成剤を付着させる工程が入らないことから、曜変模様が人工的ではなく、より自然に形成されているのが分かる。特に曜変核形成剤を付着させる工程が入らない本発明では、曜変加飾を実行する上で労力の負担を軽減させることができ、量産化により適した方法とすることが可能となる。 As can be seen from FIGS. 2 and 3, in the present invention, since the step of artificially attaching the day-changing nucleating agent does not enter, it can be seen that the day-changing pattern is not artificial and is formed more naturally. In particular, in the present invention in which the step of attaching the day-changing nucleating agent does not enter, it is possible to reduce the burden of labor in executing day-of-day decoration, and it is possible to make the method more suitable for mass production.
ちなみに、温度を最適にコントロールすることにより、上述した曜変模様を、油滴状の斑紋となるように形成させることが可能となる。 By the way, by controlling the temperature optimally, it becomes possible to form the above-mentioned day change pattern so as to be an oil droplet-like pattern.
なお、本発明は、上述した実施の形態に限定されるものではない。例えば、焼成時において、焼成室１２内の炭素濃度が１５体積％以上となるように炭素を供給することにより、成形体表面に炭素をほぼ付着させることが可能となる。 The present invention is not limited to the embodiment described above. For example, at the time of firing, by supplying carbon so that the carbon concentration in the firing chamber 12 is 15% by volume or more, it becomes possible to substantially adhere carbon to the surface of the molded body.
また、上述したプロセスは、窯焚で実行される場合に限定されず、通常の電気釜を使用して実行するようにしてもよいことは勿論である。 In addition, the above-described process is not limited to the case where the process is performed in a kiln, and may be performed using a normal electric kettle.
