Both axes have a clear casting seam (figs. 2 and 3), indicating that both objects have been cast in a bi-valve mould. Seven samples were taken using a jeweller’s saw. These were taken from each half of the axe and from the casting seam. One sample from axe AC20 is heavily oxidised and is thus excluded from this analysis. The other six specimens are triangular in shape and have dimensions of about 2 x 1 x 1 mm3, so that a cross-section of the wall both lengthwise and crosswise is present. All samples used in this research originate from the upper part of the axe (i.e. the part closest to the original socket mouth, see fig. 3).
