Seventeen pottery sherds from the seventh century BC pottery kiln uncovered at Knossos in 1993 were analysed by neutron activation at N.C.S.R. Demokritos. Fifteen of the seventeen sherds form an extremely homogeneous chemical group whose composition parallels Late Minoan I and Classical/Hellenistic pottery from Knossos. The two chemically different samples are also physically different, being much coarser and more severely burned.

Robinson, ‘Neutron Activation Analysis of Minoan Pottery from Crete: The Search for Reference Groups’ (in preparation). The three Knossian groups defined from the Manchester laboratory's data are as follows: Group 1 = LM I A and I B; Group 2 = LM II and III A; Group 3 = LM III B. The Classical/Hellenistic material has Group 1 chemistry. See also J. A. Riley, ‘The Contribution of Ceramic Petrology to our understanding of Minoan Society’, 283–92 in Krzykowska, O. and Nixon, L. (eds), Minoan Society (Bristol, 1983)Google Scholar. Riley's petrographic analysis also reveals a chronological division: pottery from LM II onwards shows a marked increase in the number of microfossils, and in he LM III B period a change of fabric.

11 The data listed in Appendices 1 and 2 have been converted to the Manchester–Berkeley standard to allow direct comparison with the chemical reference groups defined from these laboratories’ data. Factors to be applied to the ‘raw’ Demokritos data were calculated on the basis of the reanalysis at Demokritos of some seventeen pottery samples previously analysed at Manchester. These conversion factors are as follows: Na 0.95, Ca 1.167, Sc 1.055, Cr 1.251, Fe 1.051, Co 1.046, Rb 0.984, Cs 0.927, La 1.011, Ce 0.966, Sm 1.01, Eu 0.641, Yb 0.944, Lu 0.995, Hf 1.046, Th 0.859, U 0.654.
