In the first method for manufacturing a two-layered molded tile, about 20 to 80% by weight of a vitreous material containing glass cullet having a particle size of about 0.5 to 5 mm, which becomes translucent vitreous by firing, Base material that becomes non-translucent base due to
Mixing an upper layer material containing: a lower layer material serving as a lower layer base material of the tile and the upper layer material into two layers to form a two-layer molded body, and firing the two-layer molded body And a step. The second of two-layer molded tiles
Comprises a feldspar having a particle size of about 0.5 to 5 mm containing a total of about 10% by weight or more of an alkali metal oxide and an alkaline earth metal oxide, and becomes a translucent vitreous material by firing. Mixing an upper layer material containing about 20 to 80% by weight of a vitreous material and about 80 to 20% by weight of a base material that becomes a non-light-transmitting base material by firing; The method includes a step of forming a two-layer molded body by molding the material into two layers, and a step of firing the two-layer molded body. In addition, each of the above-described manufacturing methods may further include a step of polishing the surface of the fired body obtained by the firing to generate gloss on the entire surface of the fired body.

できる。The vitreous material is contained in the base material or the upper layer material in an amount of about 20 to 80% by weight, preferably about 40 to 60% by weight.
To be included. The vitreous material corresponds to the light-transmitting portion of the granite pattern, and has a role of giving depth to the pattern. If the amount of the vitreous material is less than about 20% by weight, the depth becomes poor. If the amount exceeds about 80% by weight, the vitreous material easily flows down from the upper layer during firing. Those containing about 40 to 60% by weight of a vitreous material can obtain a depth close to that of natural granite.

About 10% by weight of alkaline earth metal oxides such as O in total
Those containing the above are preferred. In particular, those containing about 13 to 15% by weight of an alkali metal oxide are preferable because the glassy material becomes difficult to flow. When the content of the alkali metal oxide and the alkaline earth metal oxide is about 10% by weight or less, transparency is reduced and it is difficult to obtain a deep surface pattern. Note that it is also possible to form a colored portion by mixing a small amount of a coloring agent such as a pigment into a vitreous material.

In addition, the base material may be formed into fine granules, or may be granulated to a particle size of about 5 mm. In addition, by using a plurality of types of base materials having different particle sizes, the non-light-transmitting portion on the tile surface can be varied. Furthermore, by mixing a colorant of a desired color such as a pigment in a part or all of the base material, the color of the tile surface can be varied.
