New shapes include the "psykter" and the "pelike". Large "krater" and "amphorae" became popular at this time. Although there is no indication that the painters understood themselves as a group in the way that modern scholarship does, there were some connections and mutual influences, perhaps in an atmosphere of friendly competition and encouragement. Thus, a vase by Euthymides is inscribed ""as Euphronios never have been able"". More generally, the pioneer group tended to use inscriptions. The labelling of mythological figures or the addition of Kalos inscriptions are the rule rather than the exception.
