EXPERIMENTATION COLOUR OF GLAZE USING A VARIOUS STONE IN SABAH

Abstract

Ceramics are the oldest art objects ever produced by humans since prehistoric times. Ceramics are made from clay and will change character when exposed to high temperatures above 1200 degrees celsius. Ceramic product is covered with a layer of glass which is a glaze and has a high resistance to temperature or heat. This research aims to document the production of glaze color systematically using various types of stone in Sabah such as Sungai Moyog stone, Lombong Mamut stone, and stone in Sports Complex, Ranau on the surface of the specimen body produced using by kaolin. In addition, this research also aims to identify the response of experimental samples using a mixture of different percentages using the formula Triaxial Line Blend on the surface of kaolin involving aspects of the material, type of combustion, and decoration techniques. The production of glaze color using natural materials which is a Sungai Moyog stone, Lombong Mamut stone, and Sports Complex stone found around Ranau and Kota Kinabalu, Sabah is an innovation in the production of color sourced from natural materials as well as efforts to develop the ceramic industry in Malaysia. It is more to the production of natural materials that have undergone the production process to produce a new glaze color. Preliminary studies using samples from color agents which are Sungai Moyog stone, Lombong Mamut stone, and Ranau Sports Complex stone were conducted experimentally. The research includes the preparation and formulation of glaze using the material until it successfully produces color pigments according to the temperature reaction and the type of combustion that has been implemented. This research also aims to study the suitability of glaze color on the surface of ceramic products such as kaolin. In conclusion, through this research, we will better understand the processes and ways how to produce glaze color in the ceramic industry by using natural materials found in the environment. Through this research as well, it is possible to identify the minerals present in the experimental materials that influence the reaction in the production of ceramic glaze color.
