Generally, the color gold has had a biased conception due to its traditional use. Thus, this bias has resulted in a lack of usage of golden glaze on ceramics and also a lack of extensive studies of such glazes. In this paper, optimum conditions and mechanism of formation of gold color crystallization glaze containing Fe2O3(hematite), which is developed for gold colors of ceramic glazes, were studied. Experimental result showed that there are pyroxene based on diopside and TiO2 phase in the base of a crystallization glaze with a value of TiO2 of 6 wt% confirmed by XRD and Raman Spectroscopy. When Fe2O3 was used as a colorant for the gold color, the TiO2 peak became extinct and the intensity of the diopside peak was sharper. Feldspar of 60 wt%, talc of 20 wt% and limestone of 20 wt% were used as the starting materials and these were tested using a three component system. The best result of test was selected and extended to its vicinity as an experiment to determine TiO2 and Fe2O3 contents. The glaze with TiO2 of 6 wt% and Fe2O3 of 12 wt% addition showed stable pyroxene based diopside crystals and the development of gold color. This gold color was obtained with CIE-L*a*b* values of 51.27, 4.46, 16.15 (a grayish yellow brown color), which was gained using the following firing conditions: temperature increasing speed 5oC/min, holding for 1 h at 1280oC, annealing speed 3oC/min till 1100oC, holding for 2 h at 1100oC, and finally natural annealing.
