PROBLEM TO BE SOLVED: To provide a method for forming a three-dimensional multi-colored shape wherein a baked layer of at least three-colors is formed on a base board, then a required sheet is affixed to the layer, and sandblasting is applied to the sheet. SOLUTION: A paint of a first color (e.g. white) for use in pottery is applied onto the surface of a base board made of a refractory material (metal plate or the like), then the board is subjected to a high temperature treatment to form a first baked color glass layer 1, and second to fourth baked color layers 2, 3, 4a, 4b are successively formed (to at least the third color layer). A sheet with a cut-off through hole pattern is adhered to the surfaces of the uppermost layers 4a, 4b, and sandblasting is repeatedly applied locally to the sheet from above by means of a thin sand nozzle, thereby leaving at least a part of each of the layers.
