摘要
以建阳当地原料红土、建瓯石、草木灰等为主要原料,研究不同Fe2O3含量对建窑兔毫釉黄色纹路及显微结构的影响规律,解析毫纹的变化机理.实验结果表明:Fe2O3含量影响着釉中ε-Fe2O3晶体析出的数量、形态及尺寸,使得毫纹呈现不同形态.Fe2O3含量为0.11 mol,釉中主要为玻璃相,析出晶体较少,形态为不规则块状,尺寸约50～100 nm,釉面呈灰青色而未出现毫纹.Fe2O3含量增至0.13～0.15 mol,ε-Fe2O3晶体析出较多,形态为短柱状,尺寸约50～150 nm,釉面形成细短蓝白色毫纹.当Fe2O3含量增至0.17～0.19 mol,ε-Fe2O3晶体发育形成单层和多层枝状晶花,尺寸约250～450 nm,釉面形成较长拉丝状黄色兔毫纹.Fe2O3含量增至0.21～0.23 mol,ε-Fe2O3晶体发育成树叶状大晶花,尺寸约1～2 μm,釉面形成柿红.釉中Fe2O3含量处于0.15～0.21 mol,釉面形成的黄色毫纹数量适中,形态纤细,呈较好的拉丝状.
Abstract
The experiment used local raw materials such as red clay,Jianou stone and plant ash from Jianyang to investigate the effect of different Fe2O3 contents on the yellow hare's fur glaze strips and structures inJian Kiln,analyzing the variation mechanism of the fur strips.The results show that the Fe2O3 content affects the quantity,morphology and size of ε-Fe2O3 crystals precipitated in the glaze,resulting in different forms of fur stripes.With an Fe2O3 content of 0.11 mol,the glaze primarily consists of a glass phase with fewer precipitated crystals,and an irregular block-like shape with a size of approximately 50～100 nm,resulting in a gray-blue glaze surface without fur stripes patterns.As the Fe2O3 content increases to 0.13～0.15 mol,more ε-Fe2O3 crystals precipitate in a short columnar form with sizes around 50～150 nm,forming fine blue-white fur stripes on the glaze surface.When the Fe2O3 content reaches 0.17～0.19 mol,ε-Fe2O3 crystals develop into monolayer and multilayered dendritic structures with sizes around 250～450 nm,resulting in longer,filamentous yellow hare's fur patterns on the glaze surface.When Fe2O3 content is 0.21～0.23 mol,ε-Fe2O3 crystals develop into leaf-like large crystal flowers,about 1～2 μm in size,resulting in a persimmon-red glaze surface.When the Fe2O3 content in the glaze ranges from 0.15～0.21 mol,an optimal quantity of yellow fur stripes with slender morphology and good filamentous characteristics is observed on the glaze surface.
