During kiln firing, the temperature must be reduced gradually. First the base color is fired in an electric kiln at 1,150oC, then the coating color is fired in a gas kiln at 1,100oC, and finally the main coloring is treated via the reduction firing technique in a gas kiln with the temperature held steady at 1,050oC.
窯燒時需逐漸降低溫度，首先，底色以電窯燒到攝氏 1,150 度，套色用瓦斯窯燒至 1,100 度，主色則仍用瓦斯窯，採「還原燒」方式，溫度先控制在 1,050 度。
