摘要
“南澳Ⅰ号”沉船位于广东汕头市南澳县南澳屿与半潮礁之间海域，是一艘明万历年间商船（1573—1620 A．D．），2007年发现并于2009年开始打捞，共出水文物近3万件，以瓷器为主，陶器数量位居第二。该文利用体视显微镜（Stereo Microscopy）、激光拉曼光谱（Raman Microscopy）、扫描电子显微镜与能谱仪（SEM-EDX）等仪器，分析了一件“南澳Ⅰ号”沉船出水酱釉刻纹彩绘陶片。分析结果表明，该陶片样品有内、外釉料层，显色元素主要为Fe与Mn。外层釉料中新发现了多种析晶，主要成分为钙长石（CaAl2Si2O8），辉石（Ca（Mg，Fe，Al）（Al，Si）2O6），钙铝榴石（Ca3Al2Si3O12）。高硅低铝型陶胎中SiO2含量为61．0％～63．9％，Al2O3含量为25．0％～27．2％，陶胎中夹杂有一定量的KAISi3O8，Fe2O3，TiO2，SiO2等颗粒。
Nan＇ao Ⅰ shipwreck site is located in the sea area between Nan＇ao island and Banchaojiao in Nan＇ao County, Shantou, Guangdong. The shipwreck found in 2007 and salvaged in 2009 was a merchant ship in the Wan Li Period of Ming dynasty （1573-1620 A. D. ）. Nearly 30,000 relics were found in the shipwreck by far. Porcelains have accounted for the vast majority and there are also many glazed pottery in-cluded. In this work, a piece of brown glaze sculptured pottery from Nan＇ao I shipwreck was analyzed by Stereo Microscopy, SEM-EDX （Scanning electron microscopy-energy dispersive X ray） and Raman Microsco py. The SEM-EDX results confirm that the sample has both inner and outer glaze layers of which the chro- mogenie elements are Fe and Mn. The composition of the outer glaze layer was qualitatively confirmed of de- vitrifications including CaAl2Si2O8 （anorthite）, Ca（Mg, Fe, Al） （Al, Si）2O6 （augite） and Ca3Al2Si3O12 （hessonite）. The body of pottery featured with high silicon and low alumina contains SiO2 of 61.0%-63.9% and Al2O3 of 25.0%-27.2%,which is mixed with particles of KAlSi3O8, Fe2O3, TiO2 and SiO2, etc.
