According to the research, study, and development of molding large ceramic products with fiberglass for ceramic entrepreneurs, currently, large ceramic works have quite difficult manufacturing processes with specific work characteristics, for instance, large pots. Most sculptural works will be created as the sculptures and have many problems in the workpiece production, as large ceramics have molding problems, distortion of the workpiece, cracking, heavy weight, easy collapse during molding, both before and after burning, and inconsistent thickness and lightness of the workpiece. Referring to the large ceramic molding problems, the researcher studied and saw that the glass fiber material, which was mainly used in the casting of glass fiber would help reinforce the workpiece strength and could be molded to be the large works. The researcher saw that glass fiber was the short fiber which could hold the structure of the clay for large ceramic products. If it is taken to assist in large ceramic work molding, it can reduce the weight of the workpiece to lighten and reduce the distortion of the workpiece. The reason was that when the fiberglass was burned, the glass would melt to be the structure, different from other materials which were burned and then disappeared. This could strengthen ceramic entrepreneurs making large ceramic products or large ceramic sculptures well. The purposes of the research are as follows: To study and develop the results of trials to bring fiber glass to adjust for use in the development of molding large ceramic products. It included the tests of the large ceramic product molding process with fiber glass to produce the prototype products by mixing local clay which was Earthenware clay having red clay and yellow clay and Stoneware clay having black clay, white clay, and short fiber glass between 1-10% to find the appropriate ratio between the fiber glass and clay to aid molding the clay. According to the experiments, the Earthenware clay used 4-10% of fiber glass to mix, and the Stoneware clay used 6-10% fiber glass mixture. The properties were analyzed by bringing the tested molding formula by extrusion, molding by the applying method, and molding by the casting method. There were three burning temperatures which were 1,000° C, 1,150° C, and 1,230° C. According to the characteristics of each clay kind, the prototype products could be built based on the temperature of the clay. The mixed clay and glass fiber could be adhered to be the structure lifting out of the mold more easily than normal. The trial results showed that bringing the short glass fiber to mix in each clay type could help in forming the structure within the clay well and decreasing the distortion, cracking, and lightweight. This was one alternative for the operators and pottery group.
