的、コスト的に困難さを伴う。2. Description of the Related Art Conventionally, crystallized glass building materials have been widely used as building finishing materials such as building exterior materials, interior materials, floor materials, and ceiling materials. By the way, the recent finishing materials for construction tend to be preferred to have various uneven patterns, and a product having an uneven pattern is also required for a crystallized glass building material. Therefore, it has been attempted to utilize a general glass surface treatment technique such as sandblasting or acid treatment, but it is difficult in terms of time and cost to obtain a desired uneven pattern.

For example, JP-A-63-230531 discloses a method in which a glass material is placed on a holding member on which a sheet having irregularities is placed and heat treatment is performed.

う問題もある。However, in the conventional method as described above, since the holding member side is the front side of the product, when the holding member is warped, this affects the surface of the product. In addition, since the load of the glass material applied to the sheet is very large, they easily react with each other during heat treatment, resulting in poor releasability. Therefore, there is an inconvenience that a release agent must be used. Further, when a sheet is used, there is also a problem that it is not possible to obtain a crystallized glass building material having a deep unevenness pattern such as a split surface of natural stone or a rough surface finish.

When heat-treated at a temperature equal to or higher than the softening point, there is no limitation as long as it has a property of precipitating crystals while being softened and deformed,
In particular, SiO 2 45 to 77 in terms of weight percentage is used as a material excellent in properties required as a building material such as mechanical strength and weather resistance.

It is preferable to use glass having a composition of 0 to 5% 2 O and having a property of precipitating β-wollastonite and diopside. The glass bodies can be used in various shapes such as powder, granules, fragments, rods, and lumps.

反応が起こり難いこと等の理由による。Next, a ceramic plate having an uneven pattern on the lower surface is placed. Here, the glass small bodies are accumulated first, and the ceramic plate is placed on the glass surface. Even if the holding member is warped, the holding member side is the back surface of the product, so that the uneven surface is formed. The reason is that there is no influence of warpage on the side and that the reaction between the two is difficult to occur because the glass body is not loaded on the ceramic plate.

しい。The ceramic material used as the ceramic plate is required to have little shrinkage and expansion due to heat treatment, to be free from cracking and alteration, and to have excellent transferability without large pores on the surface. As such a ceramic material, it is preferable to use a chamotte-based ceramic containing silica or alumina as a main component, or a ceramic composed of a refractory aggregate and a binder, such as a metal casting mold material.

Examples thereof include oxides and minerals containing 2 O 3 , ZrO 2 and the like as main components, and various salts such as MgCO 3 , CaCO 3 and CaSO 4 . Note that these may have any shape such as powder and fibrous shape. Further, the binder is capable of maintaining an appropriate mechanical strength during the heat treatment of glass, for example, hydraulic cement represented by alumina cement, ammonium phosphate, phosphates such as magnesium phosphate, gypsum, and ethyl silicate. Etc. are desirable. In addition to the above-mentioned binders, silicates, sulphates, aluminates, various sols, various clays and other refractory binders in order to increase the mechanical strength at high temperature, and the initial strength of the ceramic plate. Various natural sizing agents, synthetic sizing agents, and synthetic resins may be contained in order to enhance the heat resistance. Note that it is important to select these refractory aggregates and binders in consideration of the heat treatment temperature of glass, transferability, and releasability.

の方法で形成しておくことが望ましい。The thickness of the ceramic plate must be determined in consideration of the depth of the uneven pattern and the weight of the ceramic plate. A preferable range of the plate thickness is 5 to 50 mm, and if it is thicker than this, it is difficult to uniformly form the ceramic plate, or it becomes too heavy and workability and releasability deteriorate.
On the other hand, if it is too thin, it may be easily damaged or a deep uneven pattern cannot be obtained. The depth of the recess formed in the ceramic plate depends on the thickness of the ceramic plate, but is preferably 30 mm or less. The concavo-convex pattern of the ceramic plate may be formed at the time of molding the ceramic plate or may be formed by a method such as engraving after the molding, but in consideration of the manufacturing cost and productivity of the ceramic plate, it is formed by the former method. It is desirable to keep it.

At the same time, crystals are precipitated from the glass to obtain crystallized glass having an uneven pattern.
