摘要
以天然矿物为原料， 结合中国紫的分子式及多数考古样品的分析结果进行配料（如或多或少都含有铅）， 对配制并加工好的试样进行热重-差热及变温XRD分析， 以探讨古代烧制中国紫颜料时的原料选用及烧制条件等问题， 为揭示诸如中国紫产生在中国的原因等问题提供依据。 结果表明利用毒重石（BaCO3）配料， 能够较容易地烧制出中国紫， 这意味着中国紫的出现可能与这种独特的含钡矿物资源有关。
Abstract
In the present article, according to the molecule formula of the Chinese purple and the result of most samples analysed in archaeology (PbO was contained more or less), the raw material of Chinese purple was prepared with the natural mineral resources, then the preparation was analyzed by thermogravimetry-differential thermal analysis (TG-DTA), X-ray diffraction and thermal analysis methods for discussing which materials and what condition were used to produce Chinese purple in ancient China, in an attempt to explore the reason why the Chinese purple was invented in ancient China. The result showed that the use of witherite makes the synthetic condition facile, implying that the emergence of Chinese purple in ancient China is concerned with the use of this unique mineral containing barium.
