2006年7月,淄博市临淄区发现一座古墓葬,经抢救性发掘证明这是一座规模较大的战国墓①。墓葬为“甲”字型土坑积石木椁墓,该墓出土2件青釉罍。2016年临淄区文物局委托北京大学用能量色散X荧光光谱仪对青釉瓷垂进行了釉面成分测定。经检测,釉面化学成分检测结果如下:MgO(氧化镁)占0,56%、A1203(氧化铝)占3.89%、SiO_2(二氧化硅)占21.78%、P_2O_5(五氧化二磷)4.36%、K_2O(氧化钾)占0.7%、CaO(氧化钙)占1.71%、TiO_2(二氧化钛)占0.18%、Fe_2O_3(氧化铁)占3.99%、CuO(氧化铜)占0.03%、PbO(氧化铅)占62.07%,这两件青釉瓷罍确定为铅釉陶罍。临淄战国墓出土的这两件铅釉陶罍,是迄今经过正式考古发掘确认出自战国墓葬中唯一一例,为我国铅釉陶器出现于战国时期提供了重要依据。
In July 2006, an ancient tombs was discovered in Linzi District, Zibo City, which was proved to be a large Warring States Period by rescue excavations. Tombs for the “A ” type pit pit stone mound tomb, the tomb unearthed two pieces of green glaze. In 2016, Linzi District Bureau of Cultural Relics commissioned Peking University to measure the glaze composition of green glaze by energy dispersive X-ray fluorescence spectrometer. After testing, glaze chemical composition of the test results are as follows: MgO (magnesium oxide) accounted for 0,56%, A1203 (alumina) accounted for 3.89%, SiO_2 (silica) accounted for 21.78%, P_2O_5 (phosphorus pentoxide) 4.36% , K2O (potassium oxide) accounts for 0.7%, CaO (calcium oxide) accounts for 1.71%, TiO 2 (titanium dioxide) accounts for 0.18%, Fe 2 O 3 (iron oxide) accounts for 3.99%, CuO (copper oxide) accounts for 0.03% Accounting for 62.07%, the two green glazed porcelain 罍 identified as lead glazed Tao 罍. The two pieces of glazed pottery unearthed in Linzi Warring States Tomb are the only examples confirmed by the official archaeological excavations to date from the tombs in the Warring States Period and provide an important basis for the appearance of our lead glazed pottery in the Warring States Period.
