The Study of Mambong Clay Properties Improvement with Calcium Carbonate Addition

Abstract

Mambong pottery is a unique heritage of Kelantan state with its own identity and features. However, the fabrication technique of this pottery can be improved to gain the product quality in terms of its properties. The additional of CaCO3 as an additive opens the opportunities to improve the properties of this pottery. Four different compositions which are 0%, 5%, 10%, and 15% of CaCO3 were used in 12 hours firing duration. The slip casting method was used in this research as the modern fabrication technique. The aim of this research is to study the Mambong clay properties improvement with different compositions of CaCO3 addition.
