        The data arise from a chemical analysis of 26 samples
        of pottery found at Romano-British kiln sites in Wales,
        Gwent and the New Forest.  The variables describe the
        composition, in terms of the metals aluminium, iron,
        magnesium, calcium and sodium, and are expressed as
        percentages of the oxides of the metals.
