等のような窯業製品の表面に釉薬によって天然石のよう
に光沢部分と非光沢部分とが微妙に混在した石目調模様
の形成に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a ceramic product such as ceramics, various sanitary wares, tiles, large porcelain plates and the like. Is related to the formation of a stone-grain pattern delicately mixed.
近年、多彩な色調を有する窯業製品に対するニーズが
高まっており、そのニーズの一つとして天然石模様の形
成がある。かかる石目調模様の形成方法として、例え
ば、特開平２−124785号公報，特公平１−27032号公報
に色が異なる複数の釉薬を不均一な厚さで２層以上施釉
し、各釉薬の境界部分が相互に混じり合う温度で焼成す
る方法が開示されている。In recent years, there has been an increasing need for ceramic products having various colors, and one of the needs is the formation of natural stone patterns. As a method of forming such a stone-grain pattern, for example, Japanese Unexamined Patent Publication No. 2-124785 and Japanese Patent Publication No. 1-27032 disclose a method in which a plurality of glazes having different colors are glazed with an uneven thickness and two or more glazes are formed. A method of firing at a temperature at which the boundary portions mix with each other is disclosed.
このような方法によっても、ある程度実際の石目調模
様に近い模様を現出することはできるが、単に使用釉薬
自体が有する色調とその混合によるだけでは多種にわた
る石目調模様の顕出には充分ではない。Even by such a method, it is possible to produce a pattern close to the actual stone-grain pattern to some extent, but it is possible to reveal various stone-grain patterns simply by using the color tone of the glaze itself and its mixture. Not enough.
本発明において解決すべき課題は、窯業製品表面に従
来よりも更に複雑な石目調模様を形成するための手段を
見出して多様化ニーズに対応することにある。The problem to be solved in the present invention is to find a means for forming a more complicated stone-grain pattern on a ceramic product surface than in the past and to respond to diversification needs.
本発明は、窯業製品の素地にマット状形成釉薬と、乳
白剤と顔料とを含有し且つマット状形成釉薬よりも極端
に低い融点を有する釉薬を斑点状に施釉したのち焼成す
ることを特徴とする。The present invention is characterized in that a base material of a ceramic product is formed by applying a glaze containing a mat-like glaze, an opacifier and a pigment, and having a melting point extremely lower than that of the mat-like glaze in a spot-like manner, followed by firing. I do.

部，石灰15重量部，タルク20重量部，粘土５重量部，亜
鉛華５重量部からなり、融点が1250℃（SKが８〜９）の
石灰マグネシア系釉薬が使用できる。The above mat glaze is composed of 35 parts by weight of feldspar, 20 parts by weight of silica, 15 parts by weight of lime, 20 parts by weight of talc, 5 parts by weight of clay, and 5 parts by weight of zinc white, and has a melting point of 1250 ° C (SK is 8 to 9). Lime-magnesia glaze can be used.
また、低融点釉薬としては、融点が800〜1000℃であ
り、乳白剤と顔料とを混合しても上記マット状形成釉薬
の焼成温度において流動性を有するものが好ましい。か
かる条件をみたすためには、乳白剤と顔料との混合状態
で耐火度がSK3a〜SK10の間にある釉薬を使用する。それ
に適した釉薬として、鉛系のものがある。また、乳白剤
あるいは顔料は、粒度が平均粒径５〜10μｍのもの、例
えば珪酸ジルコンが好適に使用できる。さらに、前記釉
薬に対する含有量は、流動性の点から10〜20重量部が好
ましい。The low melting point glaze preferably has a melting point of 800 to 1000 ° C. and has fluidity at the firing temperature of the mat-like glaze even when an opacifier and a pigment are mixed. In order to satisfy such conditions, a glaze having a fire resistance between SK3a to SK10 in a mixed state of an opacifier and a pigment is used. As a suitable glaze, there is a lead-based glaze. As the opacifier or pigment, those having an average particle size of 5 to 10 μm, for example, zirconium silicate can be suitably used. Further, the content with respect to the glaze is preferably 10 to 20 parts by weight from the viewpoint of fluidity.
低融点釉薬とマット釉薬との施釉割合は、少量だと窯
変調の変化に乏しく、多量であると低融点釉薬が煮えの
状態となり、泡，ピンホール，毛穴等の表面欠陥を生じ
易いという点から、容積比率で1:4〜1:6の間が好まし
い。If the ratio of the low-melting glaze to the mat glaze is small, the change in kiln modulation is poor. If the amount is large, the low-melting glaze is in a boiled state, and surface defects such as bubbles, pinholes, and pores are likely to occur. Therefore, the volume ratio is preferably between 1: 4 and 1: 6.
焼成はマット状釉薬の焼成温度で長時間加熱する必要
がある。焼成温度がこれより低いと、単なるマットとブ
ライトとの組み合わせの装飾タイルになり、また焼成温
度がSK温度より高くなると、乳白剤が全てタイル表面を
覆うことになり、輪郭を示さなくなる。Firing requires heating at the firing temperature of the mat-like glaze for a long time. If the firing temperature is lower than this, the decorative tile is simply a combination of mat and bright, and if the firing temperature is higher than the SK temperature, the opacifying agent will entirely cover the tile surface and will not show the contour.

タイル素地の表面に施した釉薬の粘性差による内部拡散
によって促進され、みかげ石に近い自然岩の表面態様を
示す。Low-melting glaze, which is randomly glazed with an uneven thickness on the surface of ceramic products, dissolves by firing and shows high fluidity, and the opacifying agent or pigment present in the glaze surrounds the mat-like glaze. It is in a state of precipitation. This is promoted by internal diffusion due to the viscosity difference of the glaze applied to the surface of the tile base at the time of firing, and shows a surface mode of natural rock close to granite.

In the meantime, 35 parts by weight of feldspar, 20 parts of quartzite, 15 parts by weight of lime,
A mat glaze 3a consisting of 20 parts by weight of talc, 5 parts by weight of clay and 5 parts by weight of zinc white was glazed between low melting point glazes by means of spray glazing. Place this tile in an oxidizing atmosphere at 1150-1300 ° C
Heated for 20 hours. As a result, as shown in FIG. 2, a precipitation layer 4 of an opacifying agent and a pigment was formed around the mat glaze 3b, and the low melting point glaze portion 5 formed a bright layer forming a concave portion. FIG. 3 shows the surface pattern formed.
