Description

1378083 IX. Invention Description: [Reciprocal Reference of Related Application] This application is based on and claims the priority of Japanese Patent Application No. 2007-187655. This priority application was filed on July 18, 2007, its overall content. ^ Incorporated by reference. ' 4曰 : [Technical field to which the invention belongs]

I - The present invention relates to a crystallized glass article and a method of manufacturing the same, and more particularly to a crystallized glass article having a pattern applied to a building exterior, an interior material or a furniture panel, and an office panel Its manufacturing method. [Prior Art] In recent years, as the times have changed, people have been demanding various kinds of crystal enamel articles such as building exterior materials, interior materials or furniture panels, and office desk panels. As the crystallized glass used for these purposes, it includes a crystallized glass which is precipitated by the main crystal of the ash stone (call-wollastonite, /9-CaO.Si〇2), or diphthene (di〇pside). , Ca0 · Mg0 · 2Si〇2) Crystallized glass precipitated from the main crystal. In addition, the conventional production method of the crystallized glass article containing the above-mentioned crystals is as follows: (1) A method for producing a crystal from a surface to the inside by heat-treating a plate-shaped crystallized glass (see Patent Document 1); And (2) a manufacturing method of the "accumulation method", that is, the molten glass is subjected to rapid cooling treatment such as water cooling to form a crystallized glass body, and the crystallized glass body is accumulated in a fire resistance mold, and is heat-treated. A method for producing crystallized glass bodies by integrating them together (see Patent Documents 2 to 8). The crystallized glass article produced by these production methods has a pattern such as a natural marble pattern.

No. Hei. No. Hei. No. Hei. No. Hei. Japanese Patent Laid-Open No. Hei 6-24768. However, when the sheet glass is heat-treated to produce a crystallized glass article by the method disclosed in the above (丨), since the plate glass does not contain a core forming agent, the crystal is removed from the plate. The surface, the back surface, and the end of the glass are deposited and grown toward the inside. For example, a plate-like crystallized glass article having a thickness of about 8 mm has no crystallized central portion, and a glass matrix having a thickness of about 2 iran remains, and these glass matrix portions are partially cracked. Hereinafter, this state can be further illustrated by the drawings, and Fig. 4 is a cross-sectional view showing the crystallized glass article obtained by heat treatment of the above plate glass. In Fig. 4, reference numeral 100 denotes a crystallized glass article, 11〇 denotes a crystallized glass body, 12〇 denotes an uncrystallized crystalline glass precursor, and 13〇 denotes a crack. As shown in Fig. 4, the crystal grows from the front surface, the back surface, and the end surface of the sheet glass, and is stored in the field surrounded by the crystallized crystallized glass body 110 (the center portion of the sheet glass article). The crystallized glass precursor 12 〇 is formed, and these crystal glass precursors 12 are inside the raw cracks 130. Therefore, the crystallized glass material 'obtained by the production method of the above (1) does not have cracks in appearance, but cracks are present inside, and thus the strength is insufficient. On the other hand, when the crystallized glass article is produced by the accumulation method of the above (2), when the crystalline glass body is deposited in the fire resistance mold, the air is sealed in the space between the crystallized glass bodies. Air bubbles are easily generated inside the crystallized glass article. In order to process the crystallized glass article into a desired size and shape,
