摘要
"梨皮纹"是吉州窑黑釉的典型特征之一.以吉州窑黑釉为研究对象,采用高岭土、狼萁草灰和滑石等为主要原料仿制吉州窑"梨皮纹"黑釉.实验通过探究SiO2/Al2O3对吉州窑黑釉显微结构及性能的影响,揭示了独特"梨皮纹"釉面的形成机制.结果表明:当SiO2含量在4.0～5.0 mol,Al2O3含量在0.55～0.60 mol(SiO2/Al2O3:6.6～9.1),釉面形成类似吉州窑黑釉瓷独特的"梨皮纹"褶皱纹理.这主要是由于釉层在高温烧制与冷却过程中,高SiO2与Al2O3含量增大釉熔体黏度.同时,釉层氧化铁分解产生分相,生成少量赤铁矿和钙长石,以及残留石英晶体,从而使釉面形成了"梨皮纹"特征的褶皱状黑色调纹理.
Abstract
"Pear peel pattern" is one of the typical characteristics of the black glaze of Jizhou Kiln. This paper focuses on the black glaze of Jizhou Kiln,using kaolin,pteris multifida ash and talc as the main raw materials to replicate the "pear peel pattern" black glaze of Jizhou Kiln. By exploring the effects of SiO2/Al2O3 on the microstructure and properties of the black glaze in Jizhou Kiln,the formation mechanism of the unique "pear peel pattern" glaze was revealed. The results show that when the content of SiO2 is in the range of 4.0～5.0 mol and the Al2O3 content is in the range of 0.55～0.60 mol (SiO2/Al2O3:6.6～9.1),the glaze surface exhibits a unique "pear peel pattern" fold texture similar to that of Jizhou Kiln black glaze porcelain. This is mainly due to the increased viscosity of the glaze melt caused by high SiO2 and Al2O3 content during the high-temperature firing and cooling process. At the same time,the decomposition of iron oxide in the glaze layer produces phase separation,generating a small amount of hematite and calcium feldspar,as well as residual quartz crystals,thus forming a wrinkled black texture of "pear peel pattern" characteristics on the glaze.
