Title: Manufacturing method of tile, and tile
Inventor: WATANABE OSAMU
IPC: C04B33/24
Filed: 2019-04-23
Abstract: To obtain high-definition ornamental design by suppressing the spreading of tile's pattern, and to reduce the ink cost.SOLUTION: A manufacturing method of a tile 1 comprises a step of forming a ground layer 5, a step of printing by ink 7, and a step of burning the same. The ground layer 5 does not melt at a predefined burning temperature and contains opacifier. Since the ground layer 5 does not melt like a glaze layer, the spreading of the ink 7 (pigment) to the ground layer 5 is suppressed. Therefore high-definition ornamental design can be obtained without spreading of a pattern. In addition, since the spreading of the ink 7 (pigment) to the ground layer 5 is suppressed and a deep color can be produced by a small amount of the ink 7, ink cost can be also reduced.SELECTED DRAWING: Figure 5
