Community “Four Handle Jar pottery” was a major production of earthenware steamer of Hourd to store a sugar in ancient times. The research team has studied the information to develop and improve the fabrication process to be quick and easy to produce by the elderly. The results of the study and analysis revealed that the composition of stoneware clay and the earthenware clay from “Four Handle Jar pottery” to prepare the slurry was a ratio of 1 to 9 mixed clay and a specific gravity of 1.6-1.7 can be used in the process of hollow slip casting under the use of 2 pieces plaster mold. Pottery with a local identity can be used the slip casting method to save time and reduce the labour force because the group of labour is older and also produce a lot. The experiment showed that sample was a shrinkage of 12% after firing at 900 and ๑,๒๐๐ oC. The scores were at a high level of 4.๘0. The method of preparation slip was easy to understand and not complicated 4. ๗๕, neatness of plaster molds was average 4.๘๒, save time 4.6๗ , suitable for older labor 4.87, maintain the local identity 4.๙๐, reduce damaged after firing 4.๕6, can be produced in large numbers easier 4.๘๖, the hollow casting is as complete as the method of throwing 4.๖๑, control thickness of sample 4.๘ 9. The participants can be produced of hollow casting, reduce working time when compared with a throwing that requires much force to do and time to practice skill. The hollow casting need to learn how to prepare slip, demolding and decoration. From the firing of firewood kiln, it remains the unique color of the ancient pottery, good dry condition, easy to seam decoration and reduce damage after firing.
