れらを適宜組み合わせて混合したものが使用される。The inorganic pigment according to the first invention has a melting point higher than the yield point of borosilicate glass, which will be described later, and forms a flow pattern as the borosilicate glass is fluidly fused, such as spinel pigments and zircon type compounds, and glass There are transition metal oxides that develop color when melted, and these may be used alone or in an appropriate combination.
前者は、ホウケイ酸ガラスの白地に流れ模様を形成する

きる。As the latter transition metal oxide, for example, iron oxide, cobalt oxide, nickel oxide, etc. are used, and since these develop color as the glass melts, the color changes gradually depending on the degree of softening and melting of the glass particles. It can present a design.
前記ホウケイ酸ガラス粒子は一般式：

のである。The borosilicate glass particles have a general formula: % formula % (where Rt O represents an alkali metal oxide, RO represents an alkaline earth metal oxide, and x, y, z are (R, O + alkaline earth metal oxide) , X≦0,35, Y≧3゜5
, Z≧0.3. ).
Ｒ１０としては、例えば、酸化ナトリウム、酸化カリウ

。また、Ｂ、０３のモル比をＺ≧０゜３としたのは、Ｚ
＜０．３では焼成体が透明化するからである。AQtO! The reason for setting the molar ratio of X≦0.35 is that
This is because the fired body becomes transparent when X>0.35, and 5i
The reason why the molar ratio of ot is set to Y≧3.5 is that if Y is 3.5, crystals will precipitate and a --like white dough cannot be obtained. In addition, the molar ratio of B and 03 was set to Z≧0°3 because Z
This is because if it is <0.3, the fired body becomes transparent.
そして、前記ホウケイ酸ガラス粒子の粒径は０５ないし
２０開が好ましい。粒径が０ 、５ ｍｍ以下であると
、流れ模様が出にくく、直径が２０ｍｍ以上であると、
流動溶着がコントロールしにくくなり、白色生地が得に
くいからである。The particle size of the borosilicate glass particles is preferably 0.5 to 20 mm. When the particle size is 0.5 mm or less, flow patterns are difficult to appear, and when the diameter is 20 mm or more,
This is because fluid welding becomes difficult to control, making it difficult to obtain a white fabric.
前記無機顔料で前記ガラス粒子の表面を被覆する方法と
しては、ガラス粒子の表面を水又は水溶性増粘剤（例え

ール等）を薄めた水溶液で濡らした後、ガラス粒子に前
記無機顔料を０．１〜５重量％、好しくは０．５〜２．
０重量％程度の割合で混合して付着させる方法がある。The method of coating the surface of the glass particles with the inorganic pigment is to wet the surface of the glass particles with water or a diluted aqueous solution of a water-soluble thickener (for example, about 5% by weight of methyl cellulose, polyvinyl alcohol, etc.), and then , the inorganic pigment is added to the glass particles in an amount of 0.1 to 5% by weight, preferably 0.5 to 2% by weight.
There is a method of adhering by mixing at a ratio of about 0% by weight.
次に、前記無機顔料で被覆された前記ガラス粒子の流動
融着は、耐火枠体内に充填したガラス粒子をその屈伏点
よりも高い温度で焼成して行う。Next, fluid fusion of the glass particles coated with the inorganic pigment is performed by firing the glass particles filled in the refractory frame at a temperature higher than its yield point.
すなわち、耐火枠体内を約２００度／時間程度の昇温速
度で加熱し、ガラス粒子の屈伏点（５５０〜７５０度）
よりも約５００度（ガラス粒子の組成によって４００〜
７００度）高い温度域で３０〜９０分間保持して焼成し
た後、約２００度／時間で降温冷却する。That is, the inside of the refractory frame is heated at a temperature increase rate of about 200 degrees/hour to reach the yield point (550 to 750 degrees) of the glass particles.
(400 to 500 degrees depending on the composition of the glass particles)
After firing by holding in a high temperature range (700 degrees) for 30 to 90 minutes, the temperature is lowered and cooled at a rate of about 200 degrees/hour.
冷却後、耐火枠体からガラス板を取り出し、表面を研摩
して仕上げる。After cooling, the glass plate is removed from the refractory frame and its surface is polished and finished.
なお、耐火枠体の内面に軟化したガラスが付着するのを
防止するため、耐火枠体の内面に離型材としてアルミナ
、珪砂、カオリンの分散液を予め塗布しておくことが好
ましい。In order to prevent softened glass from adhering to the inner surface of the refractory frame, it is preferable to apply a dispersion of alumina, silica sand, and kaolin as a release agent to the inner surface of the refractory frame in advance.
第１発明によれば、無機顔料で被覆されたホウケイ酸ガ
ラス粒子を屈伏点以上の温度で焼成するので、無機顔料

、これにつれて前記無機顔料も流動する。そして、冷却
して流動融着した前記ガラスを固化させると、無機顔料
が流動した状態のままで固定されるので、流れ模様を有
する天然石様ガラス材が得られる。According to the first invention, since the borosilicate glass particles coated with the inorganic pigment are fired at a temperature higher than the yield point, the glass particles soften, melt and flow before the inorganic pigment melts, and as a result, the Inorganic pigments also flow. When the fluid-fused glass is cooled and solidified, the inorganic pigment is fixed in a fluidized state, so that a natural stone-like glass material with a flow pattern is obtained.
第２発明は、前述の無機顔料で被覆された前記ホウケイ
酸ガラス粒子を、無機顔料で被覆されていない前記ホウ
ケイ酸ガラス粒子に混在させて流動融着し、流れ模様が
白色生地の中で遍在するようにしたものである。In a second invention, the borosilicate glass particles coated with the inorganic pigment described above are mixed with the borosilicate glass particles not coated with the inorganic pigment and fluidly fused, so that a flow pattern is distributed throughout the white fabric. It is designed so that it exists.
すなわち、面記無機顔料が付着したホウケイ酸ガラス粒
子と、無機顔料が付着していないホウケイ酸ガラス粒子
とを耐火枠体内に所望の状態、例えば、交互に縞状に配
したり、中央部のみに無機顔料が付着したホウケイ酸ガ
ラス粒子を配するといった状態に充填し、流動融着した
ものである。That is, the borosilicate glass particles to which the surface inorganic pigment is attached and the borosilicate glass particles to which the inorganic pigment is not attached are arranged in a desired state within the fireproof frame, for example, arranged alternately in stripes, or arranged only in the central part. borosilicate glass particles to which inorganic pigments are attached are arranged and fluidized and fused.
他の条件は前述の第１発明と同様であるので、説明を省
略する。Since the other conditions are the same as those of the first invention described above, their explanation will be omitted.
第２発明によれば、完全に均一な白色生地と顔料が流動
した部分とを有する天然石様ガラス材が得られる。According to the second invention, a natural stone-like glass material having a completely uniform white fabric and a portion in which pigment has flowed can be obtained.

ためであると考えられる。In addition, in Examples 1 and 2, the glass particles fluidized and fused to exhibit a beautiful milky white color were B, 0. It is thought that this is because the glass portion containing a large amount of 5ift and the glass portion containing a large amount of 5ift exist dispersed as fine particles, thereby diffusing light at the interface between them.

It uses a glass composition that has become opalescent due to phase separation of the glass, and an inorganic pigment that is attached to the surface of the glass particles by heating and softening the glass particles at a temperature higher than the yield point and fluidizing the particles. Unlike conventional crystallized glass, small circular crystal grains are not visible, and it is possible to obtain a new natural stone-like glass that has a flow pattern similar to that of a milky white cloth.
しかも、従来例のようにガラスを結晶化させる必要がな
いので、昇温速度や温度条件を緩和できる。このため、
製造設備を簡易化でき、生産性が向上するという効果が
ある。Moreover, unlike the conventional example, there is no need to crystallize the glass, so the heating rate and temperature conditions can be relaxed. For this reason,
This has the effect of simplifying manufacturing equipment and improving productivity.
