In such a general tile tile, in the hatching process, carbon and moisture from the fuel combine to form hydrocarbons, which adhere (adhere) to the tile surface, To obtain roof tiles with such colors and unique shine.
However, when the color of the roof surface is, for example, black, it is inevitably silvery, so it is a little light black and finished, and it is difficult to obtain a dark black.
In order to obtain this dark black, there is a means of using a glaze, but when this glaze is used, the type of roof tile to be manufactured is shaped into the roof tile, for example, by a roof tile or the like. The pattern is crushed (erased) by the glaze, which is not suitable, and the glaze usually contains lead. For example, if the tile is replaced, the tile that is discarded In that case, it cannot be discarded as it is, and the processing causes various problems such as environmental pollution.
Therefore, in view of such a conventional problem, the present invention obtains a Japanese roof tile (glazed roof tile) without using a glaze containing lead and having a roof surface of a darker shade than the existing tile roof tile. It is an object of the present invention to provide a method for manufacturing a Japanese roof tile.

The above-described problems of the present invention are solved by the invention described in the following claims.

By burning the site and promoting (promoting) its carbonized state, a Japanese tile (glazed tile) having a tile surface with a darker color than the existing tiled tile is obtained.

  According to the first aspect of the present invention, it is possible to obtain a Japanese tile (glazed tile) having a tile surface with a darker color than that of an existing tile without using a glaze containing lead.

  According to the invention of claim 2, as in claim 1, a Japanese roof tile having a tile surface that is darker than existing tile roof tiles without using a lead-containing glaze like glaze roof tiles ( Can be obtained.

It is explanatory drawing which shows an example of a manufacturing process.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is an explanatory view showing an example of a manufacturing process.
Therefore, an embodiment of a method for manufacturing a tile roof as the “Japanese roof tile” of the present invention will be described.
First, a desired tile shape, for example, a tile molded body 1 such as a flat tile or a round tile is formed from a tile base made of clay having a high fireproof temperature. That is, similarly to the existing method, the tiled molded body 1 is molded by a molding machine or the like having a mold surface corresponding to the tile shape to be molded.
In this case, it is preferable that the clay having a high refractory temperature to be used has a characteristic that the refractory temperature is about 1150 ° C.

Next, the above-described roof tile molded body 1 is immersed in a clay solution in which clay having a low fire resistance temperature is dissolved, and the clay solution is soaked into the surface of the roof tile molded body. That is, clay having a low refractory temperature is dissolved in water to form a clay solution having a desired viscosity (thinness), and the clay solution is put in the container 2, and the tile-molded body is put in the clay solution W in the container 2. For example, the clay solution W is soaked in such a manner that 1 is immersed in a bumped state and extends slightly from the entire surface of the roof tile molded body 1 to the inside.
In this case, the clay having a low fire resistance temperature, which is a material of the clay solution W, preferably has a fire resistance temperature of about 1050 ° C. to 1060 ° C. Moreover, it is desirable that the clay solution W soaked into the roof tile body 1 is adhered to the surface of the roof tile body 1 as a layer of about 0.01 mm.

  And after drying the tile-shaped body 1 soaked with the clay solution W for a desired time, the tile-shaped body 1 is primarily fired in a desired firing furnace. That is, the temperature in the firing kiln is gradually increased, and the temperature is set to about 1150 ° C., and the temperature is maintained and the tile-shaped body 1 is fired over about 30 hours (primary firing). Process).

Next, the above-mentioned tile-molded body 1 after the primary firing is further fired and fired at a temperature lower than that during the primary firing in the firing furnace for a short time. That is, the temperature in the firing furnace is lowered, and the tiled body 1 after the primary firing is wrinkled at a temperature of about 950 ° C. to 960 ° C., which is lower than that at the time of the primary firing, and about 1 hour. Baking and hatching (a hatching process).
In this case, in order to promote tanning and firing, the inside of the firing kiln is sealed and a predetermined amount of oxygen is supplied into the firing kiln.

  Then, secondary firing is performed on the tile-molded body 1 after the above-mentioned calcination and firing, in which the inside of the firing furnace is set to a temperature lower than that during the above-mentioned calcination and firing, and the firing is performed in a short time. That is, secondary firing in which the tile-molded body 1 after sinter and firing is fired at a temperature of about 580 ° C. to 600 ° C., which is lower than that at the time of sinter and firing, and takes about 5 to 10 minutes. Next baking step) is performed.

  Thus, the tile-molded body 1 fired through the primary firing step, the hatching step, and the secondary firing step is taken out from the firing furnace, and the tile roof as “Japanese roof tile” is manufactured.

  The tile tiles as “Japanese roof tiles” manufactured as described above are soaked from the surface of the roof tile 1 to the inside of a desired depth before firing, and are extremely thin on the surface. The clay solution W adhered as a whole is baked in the primary firing step, the hatching step, and the secondary firing step for the roof tile molded body 1 so that the surface of the roof tile molded body 1 has a deep gloss. It can be finished in a certain color.

  In this case, in the color of the entire tile tile as the “Japanese tile”, various colors such as black and vermilion are formed depending on the material of the tile base material forming the tile molded body 1. It can be applied to colored roof tiles, and is finished in a brilliant brilliant color with a darker shade than that of conventional Japanese roof tiles.

  Therefore, the glazed roof tile as the “Japanese roof tile” manufactured by the above-described manufacturing method does not use a glaze containing lead as in the prior art. However, it does not cause problems such as environmental pollution associated with the treatment, and moreover, in the tile provided with the roof tile, the pattern and the like formed on the roof tile can be accurately formed. .

  In the meantime, the means for immersing the clay solution W in the entire surface of the tile molded body 1 described above has been described as the means for immersing in the soaking state, but is not limited to this, and also for the firing kiln. Various existing firing kilns can be employed.

  Further, each means in the above-described embodiments can be variously modified without departing from the gist of the present invention.
