The research concentrates on producing a range of pink-red colors. The objective of the study is to find a composition that will produce stable colors even at high temperatures. The pink-red color has been high in demand yet it has not been easy to maintain its consistency. The research experiments to produce the pink-red color in both glaze and pigments. The experiment uses Cr2O3, SnO2, and CaO. The study has proven that cassiterite and malayaite crystalline formations are the main factors in producing color. The crystals are also engaged by Cr2O3. Furthermore, H3BO3 is added as a mineralizer in pigment compounds to accelerate and increase the formation of malayaite. The result of this is then analyzed with the XRD method. The increase in malayaite crystals, results from the reaction caused by malayaite combined with pigment compounds, and an excess amount of Cr2O3 is produced, consequently allowing Cr2O3 to engage with malayaite. The research has proven to be important for more future experiments in producing other colors. It will contribute to other studies in understanding the color mechanism associated with other chemical components.
