Hezekiel Ntuli's unfired clay sculptures

XRF analysis was carried out on two separate occasions, one at the University of Pretoria (5 May 2023), and one at the Fort Nonquai (30 May 2023). For the XRF I made use of the Bruker Tracer 5i handheld XRF using the Geochemical three phase factory calibration covering Mg to U (Figure 41). Analysis was done on five sculptures from the Leeb du Toit Collection (annotated as LDT), ten sculptures from the Fort Nonquai Historical Museum, Eshowe KwaZulu-Natal (annotated as FN), and one sample of the original clay obtained from Hezekiel Ntuli’s son Paddy Ntuli. The data is provided in Appendix E, and results are summarised here. The data showed that the clay samples did not contain different minor and trace elements and the major elemental composition was similar (although not identical as it is natural clay taken from a riverbank, not commercially homogenised clay).
