2. Description of the Related Art Conventionally, in the case of a glazed roof tile, a white background is hung on a roof tile hanger found in Japanese Utility Model Publication No. 54-1481, and the upper part of the white background is poured with glaze and the lower part is glaze. Although it is dipped in a tank and applied with glaze, it is then dried appropriately and removed from the hanger and baked, but in such a method, only a single color can be applied, so-called glaze It is not possible to pre-form a kiln change pattern that gives an old-fashioned feeling in which the layers change in color tone over time, at the manufacturing stage,
Moreover, in the above dipping, since the high-concentration glaze is adhered to the white background only by the natural pressure, the glaze does not enter into the recesses or pinholes provided on the white surface, and the surface condition of the glaze layer deteriorates. have.

Therefore, when it is attempted to glaze a concave portion or a pinhole by only spraying the glaze,
Inevitably, a low-concentration glaze will be used, which will increase the glaze time and increase the cost, and in the case of a glazed tile that requires glaze on the backside of the roof of the roof tile main body, such a glazed tile will be extremely glazed. It had the drawback of being difficult.
