【摘要】：定窯是我國宋代五大名窯中唯一以生產(chǎn)白瓷而聞名于世的窯廠,其高超的刻印花紋技術(shù)及首創(chuàng)的支圈覆燒工藝,對(duì)國內(nèi)外許多窯場(chǎng)產(chǎn)生了深遠(yuǎn)的影響。采用(energy dispersive X-ray fluorescence,EDXRF)探索了歷代定窯白瓷的組成配方,并采用X射線吸收精細(xì)結(jié)構(gòu)(XAFS)法分析了瓷釉中Fe元素的價(jià)態(tài),以探討定窯白瓷的相關(guān)燒制工藝。研究發(fā)現(xiàn),定窯白瓷瓷胎具有典型北方瓷器"高鋁低硅"的特征,并在瓷胎中特意添加了富含CaO的礦物原料,對(duì)瓷胎的燒結(jié)有一定的促進(jìn)作用。瓷胎中的TiO2應(yīng)主要是高嶺土原料中的雜質(zhì)。定窯白瓷瓷釉具有"高鈣高鎂"特征,基本屬于鈣鎂釉或鈣鎂堿釉。其瓷釉配方中應(yīng)含有一定量的白云石或滑石。瓷釉中K2O的含量逐步增加,反映了定窯瓷釉由鈣鎂釉向鈣堿釉發(fā)展演變的過程。此外,根據(jù)瓷釉中的Al2O3,MnO和P2O5等含量的特征,可以推測(cè)釉料配方中應(yīng)添加了草木灰和高嶺土。由XAFS分析結(jié)果可知,晚唐五代時(shí)期定窯白瓷釉中Fe3+比例最高,金代次之,宋代最低,不同時(shí)期定窯白瓷皆是在還原氣氛中燒成。宋金時(shí)期定窯白瓷白中泛黃可能由于燃料煤中富含的硫在燃燒過程中與瓷釉反應(yīng),生成Fe—S化合物所致。
[Abstract]:Ding kiln is the only one of the five famous kilns in Song Dynasty, which is famous for producing white porcelain. Its superb printing pattern technology and the first branch and ring burning technology have had a profound influence on many kilns at home and abroad. The composition of white porcelain in Dingkiln was studied by (energy dispersive X-ray fluorescence spectrometry (EDXRF), and the valence state of Fe elements in porcelain glaze was analyzed by X-ray absorption fine structure (XAFS) method. It is found that the white porcelain tire of Ding kiln has the characteristic of "high aluminum and low silicon" in typical northern porcelain, and the mineral material rich in Cao is added specially to the porcelain tire, which can promote the sintering of porcelain tire to a certain extent. The TIO _ 2 in porcelain tire should be mainly impurity in kaolin raw material. Dingyao white porcelain glaze is characterized by high calcium and high magnesium, which basically belongs to calcium magnesium glaze or calcium magnesium alkali glaze. Its porcelain glaze formula should contain a certain amount of dolomite or talc. The content of K _ 2O in porcelain glaze increases gradually, which reflects the evolution process of Ding kiln porcelain glaze from calcium magnesium glaze to calcium alkali glaze. In addition, according to the contents of Al _ 2O _ 3, MNO and P _ 2O _ 5 in glaze, it can be inferred that plant ash and kaolin should be added to the glaze formula. The results of XAFS analysis show that the proportion of Fe 3 in Dingyao white glaze was the highest in the late Tang and five dynasties, followed by the Jin Dynasty and the lowest in the Song Dynasty. The yellowing of white porcelain in Ding kiln during Song and Jin dynasties may be due to the reaction of sulfur rich in fuel coal with porcelain glaze during combustion and the formation of Fe-S compounds.
