    The suitability of using traditional soil chemical and mineralogical
    methods combined with chemometrics to trace provenance of archaeological
    samples was tested on potsherds from Frederiksgave, a
    former Danish plantation in southern Ghana, in use from 18301850.
    Soil and six potsherds from Frederiksgave, together with potsherds
    from two likely production sites at Ga and Dangme Shai, were investigated
    by visual inspection, total element analysis and X-ray
    diffraction and the results analyzed by principal component analysis
    (PCA) and cluster analysis. The investigation clearly showed that
    the Frederiksgave pots were not locally produced but came from
    other production sites indicating trading interaction between the
    plantation and surrounding settlements. One sample undoubtedly
    originated from Dangme Shai and another one must have been produced
    at a third (unknown) site. The provenance of the remaining
    samples is uncertain, but possibly three of them came from Ga and
    maybe one from Dangme Shai. Ill-defined compositional variation
    at Dangme Shai and Ga sites is thought to be the main reason for
    the observed difficulties in tracing the precise provenance of the
    Frederiksgave samples.
