本発明は、綱目光沢を有する結晶化ガラスに関する。本
発明の結晶化ガラスは、建築用内外装材、家具装飾用材
料などの各種建材、装飾材として使用される。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a crystallized glass having a grain luster. The crystallized glass of the present invention is used as various building materials and decorative materials such as interior and exterior materials for buildings and materials for furniture decoration.
従来の技術とその問題点
結晶化ガラスは、天然大理石に似た外観を有しているた
め、天然大理石の代替物として使用することが提案され
ている（例えば、特公昭４７−２２７６号公報、特開昭
６０−２７６２２号公報など）。Conventional techniques and their problems Since crystallized glass has an appearance similar to natural marble, it has been proposed to be used as a substitute for natural marble (for example, Japanese Patent Publication No. 47-2276, (Japanese Unexamined Patent Publication No. 60-27622, etc.).
しかしながら、従来の結晶化ガラス表面には、タイル様
の艶、しわ、凹凸などがあり、結晶化ガラスを天然大理
石の代替物とするためには、天然大理石と同様に研磨を
施す必要があった。しかるに、従来の結晶化ガラスを研
磨しても、鏡面光沢を呈するものが得られるのみであり
、落着きのある外観を呈するもの、例えば綱目光沢を有
するものは得られなかった。However, the surface of conventional crystallized glass has tile-like luster, wrinkles, and unevenness, and in order to use crystallized glass as a substitute for natural marble, it was necessary to polish it in the same way as natural marble. . However, even when conventional crystallized glass is polished, only a product exhibiting specular luster can be obtained, and a material exhibiting a calm appearance, for example, one having a grain luster cannot be obtained.
問題点を解決するための手段
本発明者は、上記従来技術の問題点に鑑み、鋭意研究を

合的作用により達成されるものであり、以下の説明は、
その様な事実を前提として理解されるべきものである。The crystallized glass of the present invention contains 5i024 as a glass component.
0 to 60% by weight (hereinafter simply referred to as %), Al2O35 to
25%, MgO 8-15%, CaO 0.5-5%, N
A20 5-13% and F 1-5%. Below, the reason for limiting the content of each component will be briefly described. However, many of the effects achieved by the crystallized glass of the present invention are achieved through synergistic or composite effects of two or more components, and the following explanation is based on the following:
It should be understood based on such facts.
（１）ＳｉＯ２の量が４０％未満では、ガラスが失透し
やすくなり、また成形が困難になることがある。一方６
０％を越える場合と、ガラス溶融温度が高くなり、作業
上不利となる。(1) If the amount of SiO2 is less than 40%, the glass tends to devitrify and may become difficult to mold. On the other hand 6
If it exceeds 0%, the glass melting temperature becomes high, which is disadvantageous in terms of work.
（２）Ａｄ２０３の量が５％未満では、結晶化が起こり
難い。一方２５％を越えると、ガラスが失透しやすく、
また溶融性が低下する。(2) If the amount of Ad203 is less than 5%, crystallization is difficult to occur. On the other hand, if it exceeds 25%, the glass tends to devitrify.
Furthermore, the meltability is reduced.
（３）ＭｇＯの量が８％未満では、ガラスの溶融が困難
になり、また結晶化が起こり難くなる。(3) If the amount of MgO is less than 8%, it becomes difficult to melt the glass and crystallization becomes difficult to occur.
一方、２０％を越えると、溶融時にガラスの失透を生じ
やすい。On the other hand, if it exceeds 20%, devitrification of the glass tends to occur during melting.
（４）ＣａＯは、結晶化ガラスの外表面に綱目光沢を与
える要素である。この量が０．５％未満では、充分な効
果が得られない。一方５％を越えると、結晶粒が粗くな
る傾向があり、製品強度を弱くする。柔らか味と同時に
落着いた光沢を付与する範囲としては、特に１〜３％程
度が好ましい。(4) CaO is an element that gives grain luster to the outer surface of crystallized glass. If this amount is less than 0.5%, sufficient effects cannot be obtained. On the other hand, if it exceeds 5%, the crystal grains tend to become coarser, reducing the strength of the product. In particular, a range of about 1 to 3% is particularly preferable for imparting a soft taste and a calm gloss at the same time.
（５）Ｎａ２０の量が５％未満では、ガラスの溶融が困
難となる。一方１３％を越えると、結晶化ガラスの化学
的耐久性が低下する。(5) If the amount of Na20 is less than 5%, it becomes difficult to melt the glass. On the other hand, if it exceeds 13%, the chemical durability of the crystallized glass decreases.
（６）Ｆ・・・核形成剤としての機能を有する。この量
が１％未満では、核形成剤としての効果が不十分である
。一方５％を越えると、ガラス溶融時に失透し易くなる
。(6) F... Functions as a nucleating agent. If this amount is less than 1%, the effect as a nucleating agent is insufficient. On the other hand, if it exceeds 5%, devitrification tends to occur during glass melting.
本発明結晶化ガラスにおける、上記ガラス成分の含有量
は、結晶化ガラス全量の９５％以上とする。９５％未満
では、綱目光沢様の柔らか味と落ち着きを兼ね備え、研
摩不要の結晶化ガラスが得られない。The content of the above-mentioned glass components in the crystallized glass of the present invention is 95% or more of the total amount of the crystallized glass. If it is less than 95%, it will not be possible to obtain a crystallized glass that has a soft taste similar to a grain luster and a calmness, and does not require polishing.

The main crystalline phase of glass is forsterite, which exhibits a white to pale yellow color depending on the raw material composition, crystallization conditions, etc. When the crystallized glass of the present invention is formed into a plate shape, the outer surface has both a soft texture like a grain luster and a comfortable feel. When polished, it has an appearance and luster that closely resembles natural marble.
