Description
本発明は、建築物の外装材や内装材及び装飾材に用いることができる建築用結晶化ガラス物品及びその製造方法に関し、特に、耐火性、安全性を必要とする装飾用間仕切り材として好適な建築用結晶化ガラス物品及びその製造方法に関するものである。 The present invention relates to a crystallized glass article for construction that can be used for exterior materials, interior materials, and decoration materials for buildings, and a method for producing the same, and is particularly suitable as a partition material for decoration that requires fire resistance and safety. The present invention relates to a crystallized glass article for construction and a method for producing the same.
近年、建築物の形状や装飾の多様化に伴って、機能性やデザインの面から建築物に種々のガラス物品が使用されるようになっている。建築物に使用される物品の中には、有色不透明な板ガラスがある。この種の有色板ガラスには、結晶化ガラス、膜付ガラス、色ガラス等があり、建物の内外装に使用すると、ガラスのもつ質感と光沢で特有の外観を呈することになり、意匠性が要求される用途に好適となる。 In recent years, with the diversification of building shapes and decorations, various glass articles have been used for buildings in terms of functionality and design. Among the articles used in buildings, there are colored and opaque plate glasses. This kind of colored plate glass includes crystallized glass, glass with film, colored glass, etc. When used for the interior and exterior of a building, it will exhibit a unique appearance due to the texture and gloss of glass, requiring designability It is suitable for the intended use.
例えば、特許文献１には、イオン交換処理により強化された主結晶としてフォルステライト又はガーナイトを析出する結晶化板ガラスを使用した建材用の外壁材物品が開示されている。 For example, Patent Document 1 discloses an outer wall material article for building materials that uses crystallized plate glass that deposits forsterite or garnite as a main crystal strengthened by ion exchange treatment.
また、特許文献２、３には、低膨張係数の透明結晶化板ガラスを使用した透明耐火壁が開示されている。さらに特許文献４には、低膨張係数の透明結晶化板ガラスの間に樹脂フィルムを介して合わせガラスとした遮熱性の防火ガラス物品が開示されている。 Patent Documents 2 and 3 disclose transparent fireproof walls using a transparent crystallized plate glass having a low expansion coefficient. Furthermore, Patent Document 4 discloses a heat-shielding fire-resistant glass article in which a laminated glass is provided through a resin film between transparent crystallized plate glasses having a low expansion coefficient.
従来、このような有色ガラス建材は、窓ガラス等の無色透明な板ガラスに比べて熱吸収率が高く、熱割れが発生する可能性のある建築物の部位には使用が制限されている。特許文献１に記載の外壁材は、主結晶としてフォルステライトやガーナイトを析出する結晶化板ガラスの線膨張係数が４０〜８０×１０−７／Ｋであるので、直射日光や厨房などの熱線を吸収して温度が上昇する建築物の部位には使用することが困難である。 Conventionally, such colored glass building materials have a high heat absorption rate compared to colorless and transparent plate glass such as window glass, and their use is limited to parts of buildings where heat cracking may occur. The outer wall material described in Patent Document 1 absorbs heat rays such as direct sunlight and kitchen because the linear expansion coefficient of crystallized plate glass on which forsterite and garnite are precipitated as the main crystal is 40-80 × 10 −7 / K. Therefore, it is difficult to use it for a part of a building where the temperature rises.
また、特許文献２〜４に記載の透明耐火壁は、線膨張係数が−３×１０−７／Ｋであるが、透明であるので内部が透けて見え、プライバシー保護性に劣る点などで壁材には適さないという問題がある。 In addition, the transparent fire walls described in Patent Documents 2 to 4 have a linear expansion coefficient of −3 × 10 −7 / K, but are transparent so that the inside can be seen through and the privacy protection property is poor. There is a problem that it is not suitable for materials.
また、透明や半透明で単色の低膨張係数の結晶化板ガラスは、装飾性に欠けるため、装飾用間仕切り材等の用途には不向きである。 In addition, transparent, translucent and monochromatic low expansion coefficient crystallized plate glass is not suitable for applications such as decorative partition materials because it lacks decorative properties.
本発明は、建築物のあらゆる部位に使用しても熱割れの心配がなく、安全で且つ優れた装飾性を具備する有色の建築用結晶化ガラス物品及びその製造方法を提供することを課題とするものである。 It is an object of the present invention to provide a colored architectural crystallized glass article that is safe and has excellent decorativeness and a method for producing the same without being concerned about thermal cracking even when used in any part of a building.

本発明において、実質的に気泡を含まず、β−石英固溶体又はβ−スポジュメン固溶体を主結晶とし、３０〜３８０℃における平均線膨張係数が２０×１０−７／Ｋ以下である結晶化ガラスよりなり、有色半透明又は有色不透視の第一板状体としては、β−石英固溶体又はβ−スポジュメン固溶体の結晶粒径が可視光波長に比べて同等以下で半透明なもの、結晶粒径が可視光波長に比べて大きく不透視のものであれば使用可能である。また、本発明において、実質的に気泡を含まないとは、結晶性ガラス小体を焼き固める集積法等の製造方法により作成されて気泡が内在するようなものではないことを意味している。 In the present invention, from a crystallized glass that is substantially free of bubbles, has a β-quartz solid solution or a β-spodumene solid solution as a main crystal, and an average linear expansion coefficient at 30 to 380 ° C. is 20 × 10 −7 / K or less. As the first plate-like body that is colored translucent or non-colored, the crystal grain size of β-quartz solid solution or β-spodumene solid solution is less than or equal to the wavelength of visible light and is semitransparent. Anything that is largely opaque compared to the visible light wavelength can be used. Further, in the present invention, the phrase “substantially free of bubbles” means that bubbles are not created by a production method such as an accumulation method in which crystalline glass bodies are baked and hardened.
また、本発明において、実質的に気泡を含まず、β−石英固溶体又はβ−スポジュメン固溶体を主結晶とし、３０〜３８０℃における平均線膨張係数が２０×１０−７／Ｋ以下である結晶化ガラスよりなり、第一板状体とは色調が異なる第二板状体としては、第一板状体に対して、コントラストが出るような色調を有するものであれば使用可能である。例えば、第一板状体が白であれば、第二板状体は黒、透明など色調が異なるものである。 Further, in the present invention, crystallization having substantially no bubbles, β-quartz solid solution or β-spodumene solid solution as a main crystal, and an average linear expansion coefficient at 30 to 380 ° C. of 20 × 10 −7 / K or less.

For example, if the first plate-like body is white, the second plate-like body has a different color tone such as black or transparent.
さらに、本発明において、第一及び第二板状体を貼り合わせて一体化する樹脂層としては、熱可塑性樹脂、熱重合性樹脂、光重合性樹脂、熱可塑性樹脂フィルム等が使用可能である。 Furthermore, in the present invention, a thermoplastic resin, a thermopolymerizable resin, a photopolymerizable resin, a thermoplastic resin film, or the like can be used as the resin layer for bonding and integrating the first and second plate-like bodies. .
また、本発明の建築用結晶化ガラス物品は、第二板状体が透明又は有色不透視であることを特徴とする。 In addition, the architectural crystallized glass article of the present invention is characterized in that the second plate-like body is transparent or colored opaque.
本発明において、第二板状体が透明であるとは、β−石英固溶体又はβ−スポジュメン固溶体の結晶粒径が可視光波長に比べて十分小さく、透明なものであることを意味している。また、第二板状体が有色不透視であるとは、結晶粒径が可視光波長に比べて大きく不透視のものであることを意味している。 In the present invention, the second plate-like body being transparent means that the crystal particle diameter of the β-quartz solid solution or β-spodumene solid solution is sufficiently small compared to the visible light wavelength and is transparent. . In addition, the second plate-like body being colored opaque means that the crystal grain size is largely opaque compared to the visible light wavelength.
また、本発明の建築用結晶化ガラス物品は、第二板状体は、質量％でＳｉＯ２ ６４〜６６％、Ａｌ２Ｏ３ ２１〜２３％、ＭｇＯ ０．４〜０．６％、Ｌｉ２Ｏ ３〜５％、Ｎａ２Ｏ ０．４〜０．６％、Ｋ２Ｏ ０．２〜０．４％、ＺｒＯ２ １〜３％、ＴｉＯ２ １〜３％、Ａｓ２Ｏ３ ０〜２％、Ｐ２Ｏ５ １〜２％のガラス組成を有し、透明又は白色不透視であることを特徴とする。 Further, architectural crystallized glass article of the present invention, the second plate-like body, SiO 2 64 to 66% by mass%, Al 2 O 3 21~23% , MgO 0.4~0.6%, Li 2 O 3-5%, Na 2 O 0.4-0.6%, K 2 O 0.2-0.4%, ZrO 2 1-3%, TiO 2 1-3%, As 2 O 3 0 It has a glass composition of ˜2% and P 2 O 5 of 1 to 2%, and is characterized by being transparent or white opaque.
本発明において、各成分の含有量を限定した理由を以下に述べる。 The reason for limiting the content of each component in the present invention will be described below.
ＳｉＯ２はガラスのネットワークフォーマーであるとともに結晶を構成する成分である。ＳｉＯ２の含有量が６０％より少ないと熱膨張係数が高くなるとともに機械的強度が低くなり、７０％より多いとガラスの溶解が困難となって泡や失透物等の欠陥が発生する。本発明ではＳｉＯ２の含有量は６４〜６６％が好適である。 SiO 2 is a glass network former and a component constituting a crystal. When the content of SiO 2 is less than 60%, the thermal expansion coefficient is increased and the mechanical strength is lowered, and when it is more than 70%, melting of the glass becomes difficult and defects such as bubbles and devitrified substances are generated. In the present invention, the content of SiO 2 is preferably 64 to 66%.
Ａｌ２Ｏ３は結晶を構成する成分である。Ａｌ２Ｏ３の含有量が１７％より少ないとガラスの失透性が強くなるとともに化学耐久性が低下し、２７％より多いとガラスの粘性が高くなりすぎて均一なガラスが得られなくなる。本発明ではＡｌ２Ｏ３の含有量は２１〜２３％が好適である。 Al 2 O 3 is a component constituting the crystal. If the content of Al 2 O 3 is less than 17%, the devitrification of the glass becomes strong and the chemical durability is lowered, and if it exceeds 27%, the viscosity of the glass becomes too high and a uniform glass cannot be obtained. In the present invention, the content of Al 2 O 3 is preferably 21 to 23%.
Ｌｉ２Ｏは結晶を構成する成分である。Ｌｉ２Ｏの含有量が３％より少ないと所望の結晶が析出し難くなるとともに溶解性が悪くなる。一方、５％より多いとガラスの失透性が強くなり、成型が困難になる。本発明ではＬｉ２Ｏの含有量は３〜５％が好適である。 Li 2 O is a component constituting the crystal. When the content of Li 2 O is less than 3%, it becomes difficult to precipitate desired crystals and the solubility is deteriorated. On the other hand, when it exceeds 5%, the devitrification property of the glass becomes strong and molding becomes difficult. In the present invention, the content of Li 2 O is preferably 3 to 5%.
ＭｇＯは溶解性を向上させ、泡欠陥の発生を防止する成分である。ＭｇＯの含有量が０．１％より少ないとその効果がなく、泡が発生し易くなる。一方、ＭｇＯが０．９％より多いと熱膨張係数が大きくなって熱的特性が低下する。また透明結晶化ガラスの場合、ＴｉＯ２の存在によってガラスが僅かに着色することがあるが、ＭｇＯの含有量が上記範囲を超えるとこの着色が濃くなって透明性が損なわれる。本発明ではＭｇＯの含有量は０．４〜０．６％が好適である。 MgO is a component that improves solubility and prevents the occurrence of bubble defects. If the content of MgO is less than 0.1%, the effect is not obtained and bubbles are easily generated. On the other hand, if MgO is more than 0.9%, the thermal expansion coefficient increases and the thermal characteristics deteriorate. In the case of transparent crystallized glass, the glass may be slightly colored due to the presence of TiO 2 , but if the MgO content exceeds the above range, this coloring becomes dark and the transparency is impaired. In the present invention, the content of MgO is preferably 0.4 to 0.6%.
ＴｉＯ２は核形成剤として作用する成分である。ＴｉＯ２の含有量が１．３％より少ないと結晶化を促進する効果が得られず、所望の結晶が得られなくなる。一方、３％より多いと液相温度が高くなり、成型作業が困難になる。また透明結晶化ガラスの場合、ガラスが濃褐色に着色して透明性が損なわれる。本発明ではＴｉＯ２の含有量は１．３〜３％が好適である。 TiO 2 is a component that acts as a nucleating agent. If the content of TiO 2 is less than 1.3%, the effect of promoting crystallization cannot be obtained, and desired crystals cannot be obtained. On the other hand, if it exceeds 3%, the liquidus temperature becomes high and the molding operation becomes difficult. In the case of transparent crystallized glass, the glass is colored dark brown and the transparency is impaired. In the present invention, the content of TiO 2 is preferably 1.3 to 3%.
ＺｒＯ２は核形成剤として作用する成分である。ＺｒＯ２の含有量が１％より少ないと結晶化が安定して起こらない。また結晶が粗大になる結果、透明な結晶化ガラスが得られなくなる。一方、３％より多いとジルコニアの未溶解物が生じ、ガラス中に失透物が発生する。 ZrO 2 is a component that acts as a nucleating agent. When the content of ZrO 2 is less than 1%, crystallization does not occur stably. Further, as a result of the coarse crystal, a transparent crystallized glass cannot be obtained. On the other hand, when it exceeds 3%, an undissolved material of zirconia is generated, and devitrified material is generated in the glass.
なおＴｉＯ２とＺｒＯ２の合量は、２．６〜５％の範囲にあることが望ましい。これらの合量が２．６％より少ないと十分な結晶化促進効果が得られず、結晶量が少なくなって機械的強度が低下し易くなる。一方、これら成分の合量が５％より多いと失透性が強まり、均一な結晶化ガラスが得難くなる。 The total amount of TiO 2 and ZrO 2 is preferably in the range of 2.6-5%. When the total amount is less than 2.6%, a sufficient crystallization promoting effect cannot be obtained, and the amount of crystals decreases and the mechanical strength tends to decrease. On the other hand, when the total amount of these components is more than 5%, devitrification becomes strong and it becomes difficult to obtain a uniform crystallized glass.
Ｐ２Ｏ５は、核形成剤として含有されるＺｒＯ２の難溶解性を改善する効果がある成分である。Ｐ２Ｏ５の含有量が０．０５％より少ないとその効果がなく、２％より多いと分相し易くなって均一なガラスが得られない。また結晶量が多くなって透明な結晶化が得難くなる。本発明ではＰ２Ｏ５の含有量は、１〜２％であることが好適である。 P 2 O 5 is a component that has the effect of improving the poor solubility of ZrO 2 contained as a nucleating agent. If the content of P 2 O 5 is less than 0.05%, the effect is not obtained, and if it is more than 2%, phase separation is easy and uniform glass cannot be obtained. In addition, the amount of crystals increases, making it difficult to obtain transparent crystallization. In the present invention, the content of P 2 O 5 is preferably 1 to 2%.
Ｎａ２Ｏはガラスの溶解性を向上させる効果がある成分である。Ｎａ２Ｏの含有量が０．０５％より少ないとその効果がなく、１％より多いとガラスの熱膨張係数及び誘電損失が大きくなる。本発明ではＮａ２Ｏの含有量は、０．４〜０．６％であることが好適である。 Na 2 O is a component that has an effect of improving the solubility of glass. When the content of Na 2 O is less than 0.05%, the effect is not obtained. When the content is more than 1%, the thermal expansion coefficient and dielectric loss of the glass increase. In the present invention, the content of Na 2 O is preferably 0.4 to 0.6%.
Ｋ２Ｏはガラスの溶解性を向上させる効果がある成分である。Ｋ２Ｏの含有量が０．１％より少ないとその効果がなく、１％を超えると熱膨張係数及び誘電損失が大きくなる。本発明ではＫ２Ｏの含有量は、０．２〜０．４％であることが好適である。 K 2 O is a component that has an effect of improving the solubility of glass. If the content of K 2 O is less than 0.1%, the effect is not obtained, and if it exceeds 1%, the thermal expansion coefficient and the dielectric loss increase. In the present invention, the content of K 2 O is preferably 0.2 to 0.4%.
なお、Ｎａ２ＯとＫ２Ｏの合量は０．５〜２％であることが好ましい。これら成分の合量が０．５％未満の場合はガラスの溶解性が悪化し易くなり、２％を超えると結晶化ガラスの強度や耐熱性が低下し易くなる。 Incidentally, the total amount of Na 2 O and K 2 O is preferably from 0.5 to 2%. When the total amount of these components is less than 0.5%, the solubility of the glass tends to deteriorate, and when it exceeds 2%, the strength and heat resistance of the crystallized glass tend to decrease.
更に、本発明のＬｉ２Ｏ−Ａｌ２Ｏ３−ＳｉＯ２系結晶化ガラスは、上記成分以外にもＣａＯ、ＰｂＯ、Ｆ２、Ｃｌ２又はＣｅＯ２等の任意成分を各々３％以下含有させることが可能である。 Further, the Li 2 O—Al 2 O 3 —SiO 2 -based crystallized glass of the present invention contains 3% or less of arbitrary components such as CaO, PbO, F 2 , Cl 2 or CeO 2 in addition to the above components. It is possible.
また清澄剤としてＡｓ２Ｏ３やＳｂ２Ｏ３を合量で２％以下含有させることによってガラスの溶解性、作業性、均一性を向上させることができる。しかし、Ａｓ２Ｏ３を使用する場合、０．１％未満では清澄効果が低下するので、０．２〜０．４％が適量ではあるが、１％を超える使用は環境上好ましくない。 The solubility of the glass by incorporating 2% in total of As 2 O 3 and Sb 2 O 3 as a fining agent, it is possible to improve workability, uniformity. However, when As 2 O 3 is used, the clarification effect is lowered if it is less than 0.1%, so that 0.2 to 0.4% is an appropriate amount, but use exceeding 1% is not preferable in terms of the environment.
また、本発明の建築用結晶化ガラス物品は、第二板状体は、標準光Ｄ６５で１０度視野の測定条件による意匠面のＬ＊ａ＊ｂ＊表色系色度における明度Ｌ＊値が９３．０以上の白色不透視であることを特徴とする。 In addition, in the crystallized glass article for building of the present invention, the second plate-like body has the lightness L * in the L * a * b * color system chromaticity of the design surface according to the measurement condition of the standard light D65 and the 10 degree visual field. It is characterized by white opacity having a value of 93.0 or more.
本発明において、標準光Ｄ６５で１０度視野の測定条件による意匠面のＬ＊ａ＊ｂ＊表色系色度における明度Ｌ＊値が９３．０以上の白色不透視である第二板状体としては、青味、黄色味等の白色以外の色味が殆ど感じ取れない白色度を有し、透明性のないものであることを意味している。 In the present invention, the second plate shape is white non-transparent with a lightness L * value of 93.0 or more in L * a * b * color system chromaticity of the design surface under the measurement condition of the standard light D65 and a 10-degree field of view. As the body, it means that the body has whiteness such that bluishness, yellowness and other colors other than white can hardly be felt and is not transparent.
また、本発明の建築用結晶化ガラス物品は、第一板状体は、標準光Ｄ６５で１０度視野の測定条件による意匠面のＬ＊ａ＊ｂ＊表色系色度における明度Ｌ＊値が１．０以下の黒色であることを特徴とする。 Further, architectural crystallized glass article of the present invention, the first plate-shaped body, lightness in the L * a * b * colorimetric system of the design surface by the measurement conditions of the standard light D 65 10 degree field of view L * The value is black having a value of 1.0 or less.
本発明において、標準光Ｄ６５で１０度視野の測定条件による意匠面のＬ＊ａ＊ｂ＊表色系色度における明度Ｌ＊値が１．０以下の黒色である第一板状体としては、一見して不透視で黒色度の高いものであることを意味しており、暗い赤色等の長波長の光を僅かに透過する半透明なものでもよい。 In the present invention, as a first plate-like body that is black having a lightness L * value of 1.0 or less in L * a * b * color system chromaticity of the design surface under the measurement condition of a standard light D65 and a 10-degree field of view Means at first glance that it is opaque and has a high degree of blackness, and may be a translucent material that slightly transmits light of a long wavelength such as dark red.
また、本発明において第一板状体は、質量％でＳｉＯ２ ６４〜６６％、Ａｌ２Ｏ３ ２１〜２３％、ＭｇＯ ０．４〜０．６％、Ｌｉ２Ｏ ３〜５％、Ｎａ２Ｏ ０．４〜０．６％、Ｋ２Ｏ ０．２〜０．４％、ＺｒＯ２ １〜３％、ＴｉＯ２ １〜３％、Ａｓ２Ｏ３ ０〜２％、Ｐ２Ｏ５ １〜２％、Ｖ２Ｏ５ ０．０８〜１．２％のガラス組成を有し、黒色であることを特徴とする。 Further, the first plate-shaped member in the present invention, SiO 2 64 to 66% by mass%, Al 2 O 3 21~23% , MgO 0.4~0.6%, Li 2 O 3~5%, Na 2 O 0.4-0.6%, K 2 O 0.2-0.4%, ZrO 2 1-3%, TiO 2 1-3%, As 2 O 3 0-2%, P 2 O 5 It has a glass composition of 1 to 2% and V 2 O 5 0.08 to 1.2% and is black.
また、本発明において、先記で既に説明した成分以外のＶ２Ｏ５は、着色剤として作用する成分であり、本発明ではＶ２Ｏ５の含有量は、０．０８〜１．２％であることが好適である。 In the present invention, V 2 O 5 other than the components already described above is a component acting as a colorant. In the present invention, the content of V 2 O 5 is 0.08 to 1.2%. It is preferable that
また、本発明の建築用結晶化ガラス物品は、第一板状体及び／又は第二板状体は、裏面が火造り面であることを特徴とする。 In addition, the architectural crystallized glass article of the present invention is characterized in that the first plate-like body and / or the second plate-like body has a back surface that is a fire-making surface.
本発明において、裏面が火造り面である第一板状体及び／又は第二板状体としては、溶融ガラスからロールアウト成形、ダウンドロー成形等により板状体を得る方法、あるいは加工された板状体を加熱処理する方法等により得られるものがある。 In the present invention, the first plate-like body and / or the second plate-like body whose back side is a fired surface is a method of obtaining a plate-like body from molten glass by roll-out molding, down draw molding, or the like, or processed. Some are obtained by a method of heat-treating a plate-like body.
また、本発明の建築用結晶化ガラス物品は、第一板状体及び／又は第二板状体の意匠面に、高低差が０.０５〜２ｍｍ、大きさが円径換算で０．５〜１０ｍｍΦの凹凸模様を有し、かつ該意匠面が火造り面であることを特徴とする。 Further, the architectural crystallized glass article of the present invention has a height difference of 0.05 to 2 mm and a size of 0.5 in terms of a circle diameter on the design surface of the first plate and / or the second plate. It has a concavo-convex pattern of -10 mmΦ, and the design surface is a fire-making surface.
本発明において、凹凸模様の高低差が０．０５ｍｍ未満であると、模様として認識し辛く、一方、高低差が２ｍｍを超えると破損が生じ易く、かつ汚れが付着し易くなる虞がある。また、凹凸模様の大きさが円径換算で０．５ｍｍΦ未満であると、模様として認識し辛いものとなる。一方、凹凸模様の円径換算の大きさが１０ｍｍΦを超えると、成形時に裏面が平坦にならない虞がある。凹凸模様が形成されている意匠面が火造り面でないと、意匠面のうち、特に凹凸模様の部位にクラック等の多くの表面欠陥が内在することが多く、機械的強度が低下し、さらに粗面部位を有する場合には、汚れが付着し易くなる虞がある。そこで、意匠面を火造り面とすることで、表面欠陥を少なくして機械的強度を向上させ、かつ汚れが付着し難い建築用結晶化ガラス物品となる。凹凸模様が形成されている意匠面が火造り面である板状体は、ロールアウト成形法により製板する際に、一方のローラーの表面に、凹凸模様が形成されているものを使用し、凹凸模様を転写することにより、意匠面に高低差が０．０５〜２ｍｍ、大きさが円径換算で０．５〜１０ｍｍΦの所望の形状をした凹凸模様を形成したものが使用可能である。また、裏面に高い平坦性が要求される場合には、凹凸模様の円径換算の大きさを５ｍｍΦ以下とすることが好ましい。 In the present invention, when the height difference of the concavo-convex pattern is less than 0.05 mm, it is difficult to recognize as a pattern. On the other hand, when the height difference exceeds 2 mm, damage is likely to occur and dirt may be easily attached. Further, if the size of the concavo-convex pattern is less than 0.5 mmΦ in terms of a circle diameter, it is difficult to recognize as a pattern. On the other hand, if the size of the concavo-convex pattern in terms of the circle diameter exceeds 10 mmΦ, the back surface may not be flat during molding. If the design surface on which the concavo-convex pattern is formed is not a fired surface, many surface defects such as cracks are inherently present in the concavo-convex pattern portion of the design surface, resulting in a decrease in mechanical strength and further roughening. When it has a surface part, there exists a possibility that dirt may become easy to adhere. Therefore, by setting the design surface as a fired surface, it is possible to obtain a crystallized glass article for construction which improves surface strength, improves mechanical strength, and is difficult to adhere to dirt.
