Abstract
A tile having a desired pattern is provided. The pattern goes through the tile in the thickness direction. For manufacturing such a tile, e.g. a partition plate 84 is disposed in a pressure forming die 91 so as to divide its inside space into an outer forming space 95 and an inner forming space 96. Light black granules and light red granules are filled respectively in the outer and inner forming spaces 95, 96. Then, the partition wall 84 is taken out from the die 91, and lining granules are filled over the colored granules. Thereafter, they are pressed into one body and burned.
Claims26
A method of manufacturing an accessory tile having a plurality of plate portions and a three dimensional shape, said method comprising the steps of:
- forming a plurality of tile blanks having plate shapes corresponding to different ones of said plate portions;
- providing at least one of said tile blanks with a design having a plurality of colored portions corresponding to the design of said accessory tile;
- disposing said tile blanks on a pressure-forming die having a shape corresponding to the shape of said accessory tile;
- placing end surfaces of at least two of said tile blanks adjacent to each other to form a gap between said end surfaces;
- disposing a moldable joining tile material in said gap;
- pressing said tile blanks and said moldable joining tile material with said pressure-forming die to join said tile blanks via said moldable joining tile material so that said tile blanks and said moldable joining tile material form an integral body having a shape corresponding to said three-dimensional shape of said accessory tile;
- and
- burning said integral body of said tile blanks and said moldable joining tile material to form said accessory tile such that at least one of said plate portions of said accessory tile includes a design having a plurality of colored portions corresponding to the design of the colored portions of at least one of said tile blanks.
A method of manufacturing an accessory tile having an angular shape comprising first and second plate portions, said method comprising the steps of:
- pressing a tile material to form a first preformed tile blank having a plate shape corresponding to the shape of said first plate portion;
- pressing a tile material to form a second preformed tile blank having a plate shape corresponding to the shape of said second plate portion, at least one of said first and second preformed tile blanks being provided with a design comprising a plurality of colored portions;
- disposing said first and second preformed tile blanks in a forming space of a press-forming die having an angular shape corresponding to the angular shape of said accessory tile, and placing one of the end surfaces of each of said preformed tile blanks adjacent to each other with a gap;
- disposing a moldable joining tile material in said gap;
- pressing said preformed tile blanks and said joining tile material with said press-forming die to join said preformed tile blanks with said joining tile material so that the preformed tile blanks and said joining tile material form an integral body having said angular shape of said forming space of said press-forming die;
- and
- burning said preformed tile blanks and said joining tile material to form said accessory tile such that at least one of said plate portions includes a design comprising a plurality of colored portions.
