摘要
北宋的钱币成色较好,形制、工艺精美,加之有御笔和名人学士(如司马光、苏轼)的题字,所以早已引起文物、考古界的关注,不少科学工作者对此已有相当充分的研究,我们在本刊前一期发表的"北宋铜钱化学成分剖析及夹锡钱初探"一文中也做了全面的探讨。这些成果对研究北宋的政治、经济和科学技术都有重要意义。但南宋铜币由于过去出土、传世的较少,成色与制作工艺都很粗劣,对它的研究,相对地说,就极其有限,尤其是对其实物的化学与冶金学的研究至今未见有系统的报道,即使有个别的分析数据,也远不足以对南宋钱币的质量进行有说服力的评价。本文就是针对这项空白,对分属于南宋各年号的铜钱进行了化学分析研究,并考证了宋代铜锡坑冶的兴衰情况,以进行综合评述。
On the basis of an analysis of the chemical composition and purity of 32 Southern Song
coins and textual research of historical documents, this article further probes into the quality
and the prescription of coin casting. The authors hold that there was no standard of prescrip-
tion for Southern Song coins and indicate that the percentages of copper and tin decreased, whe-
reas the ferric impurity increased rapidly in the coins compared with Northern Song's. The
occurence of the above phenomenon is due to the decline of mining industry and the utilization
of 'Dantong' (produced by the reduction of CuSO_4 with Fe).
