In the early days of Taiwan local art most large houses and temples used low-temperature Koji color glaze pottery as decoration. Even today Koji pottery remains a special craft technology in Taiwan. According to visiting survey, the modern Koji pottery craft and style is different from the past. Koji pottery craftsmen prefer the Koji relics from 1840 to 1895 B.C. This period is called the period of gem glaze. Modern craftsmen most wish to imitate the vivid style of Yeh, Wang. His carmine glaze of pottery is still considered the ultimate color and style. This study utilized composition analysis and instruments to probe for Yeh’s, Wang carmine glaze composition and materials technology, and then utilize unleaded materials to imitate the glaze color. The result of the study reveals that Yeh’s, Wang carmine glaze not only used the nano gold to present color, also had less nano silver then previously thought. The study also found that potassium is better than sodium in the base of glaze composition, and that adjustments help gold to become carmine. Unleaded simulation confirms that there is no problem to present carmine.
