X-ray fluorescence mapping of copper and iron mapping in front decoration and back groove.

<p>(A) A groove is labelled by a white rectangle on the back of the casting mold sherd. One red dashed line indicates the deepest position in the groove. (B) X-ray fluorescence mapping of the copper on the back and a white dashed line encircles the groove. (C) X-ray fluorescence mapping of the iron on the back and a black dashed line encircles the groove. One side of the deepest line shows a gathering of iron, and on the other side, this reverses. (D) A probing range is labelled by a white rectangle on the front of the casting mold sherd. (E), (F) X-ray fluorescence mapping on the front decoration of copper and iron, respectively. Both elements have an uneven distribution and some correspondence to the profile of decorated patterns.</p
