Abstract

The paper reports the results of X-ray fluorescence (XRF) analysis of the composition of the alloy of a group of AD 286/287 silvered staters of the Bosporan king Thothorses from the 2011 Phanagorian hoard. For the first time, such elements as chlorine, calcium, sodium and magnesium are revealed on the surface of these coins, which suggests the use of silvering paste composed of silver chloride. Other additives might be sodium chloride, ammonium chloride, potassium-hydrogen tartrate, mercuric chloride and chalk as a thickener. A similar technique of silvering of the surface of coins was purportedly used in Roman coinage from the late third to beginning of the fourth century AD.

锡索斯州公元286/287发光金属表面的X射线微分析：博斯普兰硬币镀银过程的新数据

摘要

这篇论文报道了来自2011年帕纳戈里亚ho积者的博斯普兰国王Thothorses的一组AD 286/287镀银状态的合金的成分的X射线荧光（XRF）分析结果。这些硬币的表面首次显示出氯，钙，钠和镁等元素，这表明使用了由氯化银组成的镀银浆。其他添加剂可能是氯化钠，氯化铵，酒石酸氢钾，氯化汞和白垩作为增稠剂。据称，从公元三世纪后期到四世纪初，在罗马造币中使用了类似的对硬币表面进行镀银的技术。
