文獻對釉藥呈色劑用量之論述不同，頗令陶藝界困擾。故本研究採實驗研究法探究：(1)實驗常用釉藥呈色劑添加量與顯色能力的相關性、(2)比較常用釉藥呈色劑添加量影響釉方熔融度的差異性、(3)界定常用釉藥呈色劑添加量最適值與所顯色效果。研究結論如下： 1.呈色劑皂加量與顯色能力的相關性有四點：(1)初始顯色色相多與呈色劑原色相近；(2)呈色劑加量影響顯色相轉為相近色或強烈的對比色，差異極大；(3)呈色劑加量與顯色明度多呈現「近負相關有極限值」的關係；(4)呈色劑添加量與顯色彩度多呈現「近正相關有極限值」的關係。 2.呈色劑添加量影響釉方熔融度極具差異，影響強弱依序為：二氧化二鉻(Cr2O3)、二氧化鈦(TiO2)、氧化銅(CuO)、二氧化錫(SnO2)、碳酸銅(CuCO3)、二氧化錳(MnO2)、矽酸鋯(ZrSiO4)、三氧化二鐵(Fe2O3)與氧化鈷(CoO)。 3.以「呈色劑名、添加量、PCCS色相、明度值、彩度值」表示呈色劑添加量最適值與顯色效果，則為(1)三氧化二鐵、5-7%、帶紅色的黃、6.5-5.5、3-5S；(2)碳酸銅、2-5%、青綠、6.5-5.5、4-5S；(3)氧化銅、2-5%、青綠、5.5-4.5、5-6S；(4)氧化鈷、0.9-4.3%、青、4.5-2.5、5-8S；(5)二氧化錳、6-10%、紫棕、5.5-4.5、3-5S；(6)三氧化二鉻、2-4%、綠、6.5、2-3S；(7)二氧化錫、6-10%、白、8.5-9.5、1S；(8)二氧化鈦、5-6%、白、9.5、1S；(9)矽酸鋯、8-12%、白、9.5、1S。 研究建議：(1)探討呈色劑影響釉方熔融度的原因、(2)探究呈色劑添加量影響顯色色相轉變的原因。

Ceramic books have different opinions about the useful quantity of pigment glazes. This study used the experimental research method to explore: (1)The correlations of color manifestation abilities and quantity of pigment glazes. (2)The differences of pigment glazes’ quantity in computation of glaze formula founding. (3)The suitable quantity and manifestation colors of pigment glazes. The results are: 1.The correlations of color manifestation abilities and quantity of pigment are: (1)The beginning Hues are almost the colors of pigment glazes. (2)The quantity of pigment glazes influences Hue to appreciative or contrastive ones. (3)The correlation of manifestative Values and quantity of pigment glazes is near negative but terminus. (4)The correlation of manifestative Chromas and quantity of pigment glazes is near positive but terminus. 2.The sort what quantity of pigment glazes influences glaze formula founding is: Cr2O3, TiO2, CuO, SnO2, CuCO3, MnO2, ZrSiO4, Fe2O3, and CoO. 3.The suitable quantity and manifestation colors of pigment glazes the (“pigment glazes, quantity, PCCS Hues, Value, Chroma”): (1)Fe2O3, 5-7%, 7:ry, 6.5-5.5, 3.5S. (2)CuCO3, 2-5%, 13:bG, 6.5-5.5, 4-5S. (3)CuO, 2.5%, 14:BG, 5.5-4.5, 5-6S. (4)CoO, 0.49-4.3%, 17:B, 4.5-2.5, 5-8S. (5)MnO2, 6-40%, 4:Ro, 5.5-4.5, 3.5S. (6)Cr2O3, 2-4%, 12:G, 6.5, 2-3S.
