陶藝在地草木灰釉釉方之試驗與製備研究

An Experimental Study of Local Plant Ash Glaze Formulas in Pingtung Country

蒐集屏東農作廢棄草葉試驗與製備成草木灰釉釉方，是資源再利用、發展文創產業的一種有效方式。本研究試驗屏東縣稻梗、雜草、蓮霧枝葉與樟樹葉等四種植物枝葉灰份，用於製釉。研究目的：一、研發草木灰釉釉方，二、探究添加草木灰影響原釉方偏移方向，三、分析釉色內涵。經蒐集草木枝葉製灰，採點發散式三角座標試釉法，兩階段試驗138個釉方。結論：一、獲致屏東四種草木灰釉63個成功釉方。二、添加草木灰影響原釉方往釜戶長石端增量偏移。三、屏東草木灰釉燒成多為無（白W）與黃綠（0YW）色相、7.5N與8.5N高明度、1S與2S低彩度，適合搭配金屬氧化物（呈色劑）以獲得色澤變化與釉面效果。

Local plant leaves after calcination were added into glaze formulations for ceramic crafts to create unique local cultural products. This study used rice stalks, weeds, bell fruit leaves and camphor leaves sampled from Pingtung country. The study 1. experimented with ash glaze formulations,2. explored how grass-wood ash influences offset direction of the original glaze formulation, and 3. analyzed color contents of ash glaze. The Tri-axial Phase Diagram experimental method of glaze formulations was used with 138 ash glaze formulations by two steps. The findings were as follows.1. 63 successful Pingtung ash glaze formulations were obtained. 2. The original glaze formulation had an incremental offset to Fuhu feldspar after adding ash. 3. The hues of Pingtung' plant ash glaze are white (W) and yellow-green (0YW), high brightness 7.5N and 8.5N, and low saturation 1S and 2S. Multiple colors and glaze effects can be obtained by combining Pingtung' plant ash glaze and mental oxides as colorants.
