Abstract

The shrinkage of clay as a ceramic material is the process of changing size and weight when the water content decreases and evaporates due to drying and burning. In general, pottery craftsmen in Takalar Regency do not understand misunderstand and have not been able to be measure the shrinkage of soil material so that the results of the pottery made are always different in size and weight between the shapes of one with the others. This research was carried out in Sandi Takalar Regency with the aims of explaining a simple way of measuring the soil shrinkage properties power and predicting the shape and size of ceramic craft art made by craftsmen. Qualitative research methods were conducted with data collection techniques in the form of observation, experimentation, and recording. The sampling technique was purposive by testing local clay combinations that were considered good and existed in South Sulawesi. The results showed that all local soil experienced an average shrinkage of 1.6 cm x 0.9 cm, occurring during drying and burning. Depreciation of the average weight is 0.31 cm. Depreciation of weight during drying an average of 0.21 kg and with average combustion of 0.1 kg. The most shrinkage occurs when drying indoors and outdoors, therefore, to determine the accuracy of the desired ceramic art form, the craftsman must overestimate enlarge the wet size is about 1.6 cm x 0.9 cm from the expected shape, and exaggerates rearrange the wet weight of 0.31 kg from the weight expected to produce shape, weight, and size according to the expectations demands of the consumers and stakeholders.
