Fabrication of Mambong pottery by using slip casting method

Mambong pottery in Kuala Krai, Kelantan is one of the types of potteries in Malaysia other than
Sayong, Terenang and Sarawak pottery. Mambong pottery was being made by traditional
technique like pinching and throwing. In this research, Mambong pottery was made by using slip
casting method. This method used porous mould which can absorb the water content from the
clay slip. Different composition of water and clay was used and its effect on product properties
was investigated. Samples with different composition of water and clay were labelled as
50C50W, 60C40W, 70C30W and 80C20W samples with addition of 0.7% of sodium silicate,
Na2SiO3. The samples were characterized by its specific gravity (S.G.) of clay slip, drying and
firing linear shrinkage, density and porosity and strength of the clay samples. Finding from this
research showed that 70C30W sample is the optimum composition in fabricating pottery by using
slip casting among other samples.
