Un grupo nuevo de cerámica arcaica Griega (“Grupo H”) fabricado en Tartessos (Huelva, España)

To the production by Greek residents in Huelva of pottery characterised by yellowish-green clay, a second ceramic group distinguished by yellowish, orange or reddish clay, and frequently red slipped, conventionally nominated “Group H” can now be added. The preliminary study of two pieces had already aimed at a local production of the new group. This fact is supported by the results of an additional study based on the Neutron Activation Analyses of 10 ceramic specimens conclusively indicating a close resemblance to the chemical composition of clays from local deposits near the habitat. Likewise, as in the group of the yellowish-green clay, a striking contamination with precious metals, gold and especially silver, was detected in some of the fragments. The representation of both groups suggests that a significant percentage of the Archaic Greek vessels found in Huelva was manufactured in situ .
