Description

本発明は、飾りをちりばめた陶磁器の製造方法に関し、飾りの色が釉薬の色に覆われることなく、高コントラストで人造星砂を固定した陶磁器の製造方法に関する。   The present invention relates to a method for manufacturing ceramics with ornaments, and more particularly, to a method for manufacturing ceramics in which artificial star sand is fixed with high contrast without the decoration color being covered with glaze.

沖縄県の竹富島や西表島のビーチでは星の形をした砂がみられ、この砂を利用した星砂ボトルや星砂キーホルダー等が沖縄を象徴する土産物として人気を博している。本発明者は、この星砂を陶磁器の飾りとして用いることを検討してきたが、星砂自体は有孔虫の死骸であり、600℃程度に加熱すると分解しいバラバラに崩れてしまうため、陶磁器の製造に不可欠な焼成等の熱処理ができないという問題がある。   Star-shaped sand can be seen on Taketomi Island and Iriomote Island beaches in Okinawa Prefecture. Star sand bottles and star sand key chains using this sand are popular as souvenirs symbolizing Okinawa. The present inventor has studied using this star sand as a ceramic ornament, but the star sand itself is a foraminiferal dead body, and when it is heated to about 600 ° C., it collapses into pieces that cannot be decomposed. There is a problem that heat treatment such as firing, which is indispensable for manufacturing, cannot be performed.

そこで、実際の星砂の代わりに、同程度の大きさの2〜5mmの星形形状の白色の陶器を作り、これを星砂として用いて表面にちりばめた皿や椀を製造する検討を試みた。
まず、人造星砂として、杯土を型に入れて星形にし、これを乾燥した後、素焼き後、本焼きした物を多数用意しておく。一方、同様に杯土を皿形状に形成して、乾燥した後、素焼きする。
続いて、皿の上に.星砂を配置して、釉薬をかけて固定し、その後本焼きして陶磁器としての皿を完成する。ここで、沖縄のビーチの青い海、空のイメージを表現するために、釉薬には濃紺色や濃緑色の釉薬が用いられる。
Therefore, instead of the actual star sand, we tried to make a 2-5mm star-shaped white earthenware of the same size, and use this as the star sand to produce a dish or cocoon studded on the surface. It was.
First, as artificial star sand, put the earthen earth into a mold and make it into a star shape, and after drying this, prepare a large number of baked things after unbaking. On the other hand, similarly, the clay is formed into a dish shape, dried, and then unbaked.
Then on the plate. Place star sand, fix it with glaze, and then burn it to complete a ceramic dish. Here, dark blue or dark green glaze is used for glaze to express the image of the blue sea and sky of Okinawa beach.

なお、釉薬をかけて陶器を一体化(固定化)する方法等については、例えば特開2001−328858等に開示されている。
特開2001−328858で開示されているのは陶土で急須本体およびこし器部分を成形し両部分の素焼きを行った後に、本体とこし器部分を釉薬を用いて一体化させる技法が開示されているものである。
A method for integrating (fixing) ceramics by applying glaze is disclosed in, for example, Japanese Patent Application Laid-Open No. 2001-328858.
Japanese Patent Laid-Open No. 2001-328858 discloses a technique in which a teapot main body and a strainer part are molded with porcelain, and both parts are unglazed, and then the main body and the strainer part are integrated using a glaze. It is what.

特開2001−328858JP 2001-328858 A

しかしながら、濃い色の釉薬を用いると、白い星砂がそれにおおわれてしまい、折角の星砂のイメージが消失してしまうという問題があった。また、焼成完了までの途中の工程で星砂が動いてしまい、所望の位置関係(デザイン)のものが得られなかったり、場合によっては星砂が重なってしまうという問題が生じた。この問題は、星砂の大きさが小さくなるにつれて、より顕著になった。   However, when dark-colored glaze is used, white star sand is covered with it, and there is a problem that the image of the broken star sand disappears. Moreover, the star sand moved in the process before the completion of firing, and the desired positional relationship (design) was not obtained, or the star sand overlapped in some cases. This problem became more pronounced as the size of the star sand decreased.

このような状況において、本発明は、微小な飾りであっても、所望の位置に再現性良く配置できる陶磁器の製造方法を提供することを目的とする。また、濃い背景色の中でも、異なる色の飾りを高いコントラストで配置することが可能な陶磁器の製造方法を提供することを目的とする。 In such a situation, an object of the present invention is to provide a method for manufacturing a ceramic that can be arranged at a desired position with high reproducibility even if it is a minute decoration. It is another object of the present invention to provide a method for manufacturing ceramics, in which ornaments of different colors can be arranged with high contrast among dark background colors.

本発明の飾りをちりばめた陶磁器の製造方法は、
予め、杯土を所定の形状に成型し、乾燥後、焼成して作製した陶器を用い、これを飾りとしてちりばめた陶磁器の製造方法であって、
杯土を成型し、乾燥して、所定の形状の器を作製する工程と、
前記器の表面に、前記飾りをちりばめて配置し、少なくとも前記飾り及びその上に、第1釉薬の水溶液をかける第1施釉工程と、前記器を乾燥した後、前記第1釉薬が半溶融状態となる温度に加熱して仮焼きする仮焼工程と、仮焼工程後に、前記第1釉薬よりも高い融点を有する釉薬であって、前記飾りの色とは異なる色の第2釉薬の水溶液を前記器にかける第2施釉工程と、該器を乾燥後に、前記第2釉薬の融点以上の温度で前記器を焼成する本焼工程を有し、
前記第1釉薬は、無色のガラス粉であり、且つ前記第2釉薬の水溶液の濃度は50〜60重量%としたことを特徴とする
The method of manufacturing ceramics studded with the decoration of the present invention is as follows:
A method for producing ceramics, in which a clay is molded into a predetermined shape in advance, dried, baked, and then used as a decoration.
Molding the clay and drying it to produce a container with a predetermined shape;
A first glaze step in which the ornament is scattered on the surface of the vessel, and at least the ornament and an aqueous solution of the first glaze are applied thereon, and after the vessel is dried, the first glaze is in a semi-molten state A calcining step of calcining by heating to a temperature to become a glaze having a melting point higher than that of the first glaze after the calcining step, and an aqueous solution of the second glaze having a color different from the color of the decoration A second glazing step to be applied to the vessel; and a baking step in which the vessel is baked at a temperature equal to or higher than the melting point of the second glaze after the vessel is dried,
The first glaze is colorless glass powder, and the concentration of the aqueous solution of the second glaze is 50 to 60% by weight .

すなわち、人造星砂等の飾りに第1釉薬をかけ、半溶融状態に仮焼きすることで、その後に濃色の釉薬をかけてより高温の本焼き工程を経ても、飾りが濃色の釉薬でかくれてしまうことなく、高いコントラストで飾りを確認することができる。   In other words, the first glaze is applied to decorations such as artificial star sand and calcined in a semi-molten state, and then the dark glaze is decorated even after a higher temperature main baking process by applying dark glaze. The decoration can be confirmed with high contrast without being lost.

また、例えば2〜5mmの小さな飾りであっても、飾りの位置はほとんど変動することなく、デザイン通りの配置を維持することができる。 Moreover, even if it is a small decoration of 2-5 mm, for example, the position of the decoration hardly changes and the arrangement as designed can be maintained.

本発明において、第1釉薬として使用するガラス粉は通常、釉薬の融点を下げる為の調整用として使用されるが、本発明はガラス粉の透明なガラス質の釉薬が800〜1000℃で半溶融ガラス質の特性を活かして本体と人造星砂を固定する方法として用いて進歩性をもたせた。また、飾りの色をより忠実に表現することができる。第2釉薬水溶液の濃度は50〜60重量%とするのが好ましく、この範囲で、飾りの細かい形状であっても、より高いコントラストで観ることができる。   In the present invention, the glass powder used as the first glaze is usually used for adjustment to lower the melting point of the glaze, but the present invention is a glass powder transparent glassy glaze that is semi-molten at 800-1000 ° C. Taking advantage of the vitreous properties, it was used as a method to fix the main body and artificial star sand, giving it an inventive step. In addition, the color of the decoration can be expressed more faithfully. The concentration of the second glaze aqueous solution is preferably 50 to 60% by weight. Within this range, even a finely decorated shape can be seen with higher contrast.

本発明は、特に、陶器からなる白色の人造星砂と、釉薬で濃紺色や濃緑色に着色した背景と、からなる皿や椀に好適に用いられるが、これに限るものでなく、飾りについては、例えば雪の結晶構造等、様々な形状を用いることができ、また、釉薬に含まれる顔料やその濃度、焼成条件等によって種々の背景色を選択することができる。
なお、本発明において、釉薬の融点とは、釉薬全体が完全に溶融する温度を言う。また、軟化点とは、溶解開始温度を言う。
The present invention is particularly suitable for a white artificial star sand made of earthenware, and a plate or agate made of a glaze colored dark blue or dark green with a glaze, but is not limited to this. For example, various shapes such as a crystal structure of snow can be used, and various background colors can be selected depending on the pigment contained in the glaze, its concentration, firing conditions, and the like.
In the present invention, the melting point of the glaze refers to a temperature at which the entire glaze is completely melted. The softening point refers to the melting start temperature.

本発明により、飾りが釉薬の色で見えなくなるという不具合を解消し、高コントラストで表すことができる。また、飾りの位置も焼成工程等でもほとんど移動しないことから、デザイン通りに飾りをちりばめた陶磁器を再現性良く、安定して製造することができる。特に、沖縄の青い海や空と白い星砂を陶磁器に表現するのに好適な方法である。   By this invention, the malfunction that an ornament becomes invisible with the color of a glaze is eliminated, and it can express with high contrast. In addition, since the position of the decoration hardly moves even during the firing process or the like, it is possible to stably manufacture ceramics with the decoration as designed with good reproducibility. In particular, it is a suitable method for expressing the blue sea and sky of Okinawa and white star sand in ceramics.

本発明の製造方法の一例を示すフォローチャートである。It is a follow chart which shows an example of the manufacturing method of this invention. 人造星砂を一皿の中に一体化した平面図である。It is a top view which integrated artificial star sand in one plate. 人造星砂を碗の中に一体化した断面図である。It is sectional drawing which integrated the artificial star sand in the cage.

本発明の実施形態を図1のフォローチャートを参照して説明する。
まず、飾り陶器を準備しておく。杯土を所定の形状にくりぬいた型に入れ、乾燥させた後、型から取りだし、例えば、1200〜1250℃で13〜15時間程度焼成し本焼きの飾り陶器を作製する。杯土には、例えば、信楽系白粘土、陶磁器用白粘土等が好適に用いられる。
一方で、器を成型する。ろくろ等を用いて、杯土で器を形成、加工等した後、
一週間程度乾燥させる。乾燥した器に飾りを設置、取り付け等して、所望のパターンに配置する。
An embodiment of the present invention will be described with reference to the follow chart of FIG.
First, prepare decorative ceramics. The dough is put into a mold hollowed into a predetermined shape, dried, and then taken out from the mold, and baked at 1200 to 1250 ° C. for about 13 to 15 hours, for example, to produce a baked ornamental pottery. For example, Shigaraki white clay, white clay for ceramics, or the like is preferably used for the clay.
Meanwhile, mold the vessel. After using a potter's wheel etc. to form and process a vessel with clay,
Let dry for about a week. Place the ornament on the dried vessel, place it in a desired pattern, etc.

続いて、第1釉薬の水溶液を、飾りの上に盛るようにかけた後、乾燥させる。
ここで、第1釉薬は、ソーダガラス等のガラス粉が好適に用いられる。溶解開始温度が730℃で、完全に溶融する温度が1100〜1200℃程度である。
また、第1釉薬の水溶液の濃度は、50〜60重量%とするのが好ましく、この濃度では液は粘性を帯びている。なお、第1釉薬は、飾りの色をそのまま表す場合は無色とするのが一般的である。
Subsequently, an aqueous solution of the first glaze is applied on the decoration and then dried.
Here, as the first glaze, glass powder such as soda glass is preferably used. The melting start temperature is 730 ° C., and the melting temperature is about 1100 to 1200 ° C.
Moreover, it is preferable that the density | concentration of the aqueous solution of a 1st glaze shall be 50-60 weight%, and a liquid is viscous at this density | concentration. The first glaze is generally colorless when the color of the decoration is expressed as it is.

続いて、乾燥した器を第1釉薬が半溶融状態となる温度で8時間程度仮焼する。温度としては、通常800〜900℃が用いられる。
冷却した後、顔料を含んだ第2の釉薬を塗布し水分が抜けるまで乾燥させる。第2釉薬水溶液の濃度は50〜60重量%が好ましい。
最後に、器を第2釉薬が完全に溶融状態になる温度に加熱して、焼成する。通常、焼成温度としては1210〜1230℃、 焼成時間としては13〜15時間が用いられる。
焼成後、冷却して得られた陶器の飾りは、顔料色を背景に、埋もれることなく浮き上がったコントラストの高い模様を得ることができる。
また、図1では省いてあるが、器を形成、加工し、乾燥した後に、飾りを配置する構成としたが、器を例えば800〜900℃で素焼きする工程を設け、この後に、飾りを配置する構成としても良い。
Subsequently, the dried vessel is calcined for about 8 hours at a temperature at which the first glaze is in a semi-molten state. As temperature, 800-900 degreeC is normally used.
After cooling, a second glaze containing the pigment is applied and dried until moisture is removed. The concentration of the second glaze aqueous solution is preferably 50 to 60% by weight.
Finally, the vessel is heated to a temperature at which the second glaze is completely melted and fired. Usually, the firing temperature is 1210 to 1230 ° C., and the firing time is 13 to 15 hours.
After firing, the ceramic ornament obtained by cooling can obtain a high contrast pattern that floats without being buried against the background of the pigment color.
In addition, although omitted in FIG. 1, the decoration is arranged after the vessel is formed, processed and dried, but a step of baking the vessel at, for example, 800 to 900 ° C. is provided, and then the ornament is arranged. It is good also as composition to do.

以下に実施例を挙げて,本発明をより詳細に説明する。   Hereinafter, the present invention will be described in more detail with reference to examples.

(実施例1)以下の手順に従い、青色地に白色の人造星砂をちりばめた皿を図2に示した。 (Example 1) FIG. 2 shows a dish in which white artificial sand is scattered on a blue background in accordance with the following procedure.

工程1(人造星砂3の製造工程)
複数の5角形の星形の孔を形成した型板に杯土信楽系陶磁器用白粘土を詰め込み、15分間放置した。杯土を乾燥、収縮させて、型板から取り出し、1250℃に設定した電気炉(シンポ株式会社製DMT01)に入れて、12時間、焼成した。冷却後、得られた人造星砂は、白色で、厚さ1mm、大きさ5mm(外接円の直径)であった。
Process 1 (Manufacturing process of artificial star sand 3)
White clay for Gobuchi Shinraku ceramics was packed into a template with a plurality of pentagonal star holes and left for 15 minutes. The clay was dried and shrunk, removed from the template, placed in an electric furnace (DMT01 manufactured by Shinpo Co., Ltd.) set at 1250 ° C., and baked for 12 hours. After cooling, the resulting artificial star sand was white and had a thickness of 1 mm and a size of 5 mm (diameter of circumscribed circle).

工程2(皿本体と人造星砂との一体化工程)
杯土信楽系陶磁器用白粘土などを用いて、ろくろで直径15cmの皿を作製し、1週間放置して乾燥させた。その後、皿の上に上記の人造星砂を10個程
度配置し、第1釉薬となるNaO−CaO−SiOを主成分とする透明ガラス粉(草場善兵衛商店製UP−09L)100gに対し水85gの割合で混合したガラス粉水溶液(54重量%)を、砂表面がかくれるまで星砂の上に盛
り上げた。これを、放置して乾燥させたところ、星砂表面は白濁色となり、皿本体表面は素地とガラス粉を載せた部分は凹凸ができた。
Process 2 (Integration process of dish body and artificial star sand)
Using a clay clay white clay for clay, etc., a dish with a diameter of 15 cm was prepared with a potter's wheel and left to dry for one week. Thereafter, about 10 artificial star sands are placed on a plate, and 100 g of transparent glass powder (UP-09L, manufactured by Kusaba Zenbei Shoten) containing Na 2 O—CaO—SiO 2 as a primary glaze as a main component. a glass powder solution in a mixing ratio of water 85g (54 wt%), were raised on the star sand until hide is star sand surface. When this was left to dry, the surface of the star sand became cloudy and the surface of the dish body was uneven on the substrate and glass powder.

次に、800℃に設定した電気炉内に皿を配置し、仮焼(8時間程度)した。本実施例のガラス粉は、軟化点が730℃で、完全に融解する温度が略1200℃であることから、電気炉での加熱によりガラス粉は全体が溶融するのではなく、一部が固体状態の半溶融状態となっていた。冷却後、取り出した皿の表面は、部分的に星が白濁して見えなくなっていることが分かった。なお、素焼きにおいて半溶融状態の部分が冷却後に白濁部分に対応し、この白濁部分が星砂と本体との一体化や固定化に重要な作用をするものと思われる。
第1釉薬を半溶融状態に形成することにより、本焼き工程においても人造星砂が移動することなく、デザイン通りの位置に人造星砂は一体化して固定されていることが分かった。
Next, the dish was placed in an electric furnace set at 800 ° C. and calcined (about 8 hours). Since the glass powder of this example has a softening point of 730 ° C. and a complete melting temperature of about 1200 ° C., the glass powder is not melted entirely by heating in an electric furnace, but partly solid. It was in a semi-molten state. After cooling, the surface of the removed dish was found to be partially clouded with stars. In the unglazed baking, the semi-molten part corresponds to the cloudy part after cooling, and this cloudy part seems to play an important role in the integration and fixation of the star sand and the main body.
By forming the first glaze in a semi-molten state, it was found that the artificial star sand was integrated and fixed at the position as designed without moving the artificial star sand even in the main baking process.

工程3(色づけ、本焼き工程)
素焼きした皿に、紺色顔料を含む青ガラス釉薬2(草場善兵衛商店製KGP−04F、溶融温度1150℃,主成分:酸化コバルト、長石、石灰石、土灰)100gに対し、水67ccの割合で混合した水溶液を皿全体にかけ、乾燥後、1220℃に設定した電気炉に入れ、13時間本焼き焼成した。ここで、青ガラス釉水溶液の濃度は、60重量%である。
Process 3 (coloring and baking process)
In an unglazed dish, blue glass glaze 2 containing amber pigment (KGP-04F, Kusaba Zenbei Shoten, melting temperature 1150 ° C., main components: cobalt oxide, feldspar, limestone, earth ash) at a rate of 67 cc of water The mixed aqueous solution was put on the whole dish, dried, put into an electric furnace set at 1220 ° C., and baked for 13 hours. Here, the concentration of the blue glass soot solution is 60% by weight.

作製した皿の星砂は、濃紺色の背景に覆われることなく白色がはっきりと浮かび上がって見え、本実施例の製造方法により、コントラストの高い白色星砂が得られることが確認された。また、星砂の位置も焼成時に移動することはなく、設計通りのデザインとすることができた。   The star sand of the prepared dish appears to be clearly white without being covered with a dark blue background, and it was confirmed that white star sand with high contrast can be obtained by the production method of this example. In addition, the position of star sand did not move during firing, and the design was as designed.

また、青ガラス釉の代わりに、トルコ青ガラス釉薬(草場善兵衛商店製KG
P−02F、溶融温度1150℃,主成分:酸化銅、長石、石灰石、土灰)をかけ、1230℃で15時間、焼成したところ、濃緑色の地に白色の人工星砂を高いコントラストでちりばめた皿を作製することができた。
又、比較のために素焼きを行い青ガラス釉を施釉し、その上に人造星砂を置きガラス粉を乗せ1230℃(13〜15時間)焼成して試料を作成したところ星砂同士が重なったり、又白い星」砂の色が濃紺色で覆われてコントラストが低下する事が分かった。
In addition, instead of blue glass bowl, Turkish blue glass glaze (KG made by Kusaba Zenbei Shoten)
P-02F, melting temperature 1150 ° C., main components: copper oxide, feldspar, limestone, earth ash) and fired at 1230 ° C. for 15 hours. White artificial star sand is scattered on dark green ground with high contrast. We were able to make a dish.
In addition, for comparison purposes, unglazed and glazed blue glass glazing, artificial star sand was placed on it, glass powder was placed on it, and the sample was made by baking at 1230 ° C (13 to 15 hours). Also, it was found that the contrast of the white star sand was covered with a dark blue color and the contrast was lowered.

人造星砂を配置してガラス粉をかける前に、800℃で素焼き(8〜9時間)した以外は、実施例1と同様にして、人造星砂をちりばめた皿を作製した。
実施例1の場合と同様に、濃紺色地に白い星砂がくっきりと浮かび上がることが分かった。
Before placing the artificial star sand and applying the glass powder, a dish in which the artificial star sand was interspersed was produced in the same manner as in Example 1 except that it was unbaked at 800 ° C. (8 to 9 hours).
As in the case of Example 1, it was found that white star sand clearly emerged on the dark blue background.

また、青ガラス釉の水溶液濃度を、40〜70重量%と変えた以外は、実施例1と同様にして皿を作製した。
この結果、青ガラス釉濃度は50 〜60重量%で星砂のコントラストが高くなり、65重量%以上では星砂上で濁った紺色となりコントラストが低下したり、釉薬の貫入、亀裂が大きくなることが分かった。また、45重量%以下では、十分な濃紺色の背景地が得られず、また、色の均一性が低下することが分かった。
なお、ガラス粉(第1の釉薬)は、50重量%以上が好ましく、50重量%以下で、星砂の突起が消えてしまう場合が多く観られた。
以上、実施例では、皿に適用した場合について説明してきたが、皿の他、碗種々の器についても同様にして作製可能である。
Moreover, the dish was produced like Example 1 except having changed the aqueous solution density | concentration of the blue glass koji with 40 to 70 weight%.
As a result, the contrast of star sand is high when the concentration of blue glass soot is 50 to 60% by weight, and when it is 65% by weight or more, it becomes a cloudy amber color on star sand and the contrast is lowered, and the penetration of the glaze and cracks increase. I understood. It was also found that when the amount was 45% by weight or less, a sufficiently dark blue background could not be obtained, and the color uniformity deteriorated.
The glass powder (first glaze) is preferably 50% by weight or more, and when it is 50% by weight or less, the star sand protrusions often disappear.
As described above, in the embodiments, the case where the present invention is applied to a dish has been described. However, in addition to a dish, various types of bowls can be similarly produced.
