The present invention relates to a method for making an irregular crack pattern on an outer surface of a container, comprising the following steps of: a) preprocessing a surface of a material to be applied to remove foreign substances such as dust, dirt, or the like thereon; b) applying a coupling agent for improving an adhesive strength between the surface of the material and a polymer resin; c) drying the applied coupling agent; d) undercoating the surface of the material on which the coupling agent is dried with a suitable polymer resin monomer composition; e) overcoating the undercoated surface of the material with a suitable polymer resin monomer composition; f) spraying a pattern agent and applying the same on the overcoated surface of the material; g) heating the material on which the pattern agent is sprayed and applied at a suitable temperature; and h) cooling the material having a pattern formed by heating, and packaging the same, wherein the steps are sequentially performed on one painting line as one line method. Accordingly, a crack pattern having irregular shapes or sizes is formed on an outer side of a container, plate, or the like made of materials such as ceramics, glass, metal, aluminum, or the like, thereby improving overall design of the container and increasing an added value of the container or a product accommodated in the container according to the improvement of the design thereof so as to improve competitiveness and satisfy preference and taste of a consumer or a buyer. |
