摘要
以建阳当地原料红土、建瓯石、草木灰等为主要原料,制备了一种蓝底黄毫的兔毫釉.通过XRD、Raman、SEM、EDS等测试方法,探究烧成温度对建窑黄兔毫釉毫纹的影响规律及作用机理.实验结果表明:兔毫釉烧成温度范围较窄,在较低温度1270～1290 ℃下,釉中主要是分相-析晶,毫纹处ε-Fe2O3晶体尺寸为150 nm,釉中由于高温液相黏度较大晶体无法迁移形成釉面斑点;随着烧成温度升高至1310℃,釉面出现毫纹,釉浆黏度逐渐减小,釉中结构完成分相向析晶的转变,毫纹中的ε-Fe2O3晶粒数量增加,尺寸为300 nm,底釉中的晶核逐渐向毫纹中迁移,导致1350℃以上釉面逐渐呈现密集的黄色毫纹.在1330 ℃的兔毫釉釉浆黏度适中,底釉略微泛蓝,毫纹形态为细长的拉丝状,清晰分明,效果较佳.
Abstract
The experiment produces a blue-and-yellow striped hare's fur glaze using Jianyang's local raw materials,including red clay,Jian'ou stone,and plant ash.It investigates the effect and mechanism of firing temperatures on the yellow hare's fur glaze of Jian wares by XRD,Raman,SEM,EDS and other testing methods.The findings indicate that hare's fur glazes have a restricted firing temperature range.At lower temperatures between 1270 ℃ and 1290 ℃,the glaze mainly contains separated-crystal structures;the Fe2O3 crystals are 150 nm,and they cannot move to form glaze spots due to increased viscosity.With the firing temperature increasing to 1310℃,strips began to appear and the viscosity decreased gradually,completing the transition from separated to crystals.The base glaze's crystal nuclei gradually migrate into the strips as the amount of Fe2O3 crystals increases,and its size is 300 nm,as a result,the glaze gradually develops dense yellow stripes above 1350 ℃.At 1330 ℃,the hare's fur glaze paste viscosity is moderate,the base glaze is slightly bluish,and the shape of the strips is slender and thread-like,well defined,and more effective.
