It is widely assumed that Etruria traded lump iron, lead and bronze in exchange for Greek pottery.
Corinth dominated the pottery export trade up to the mid 6th century BC. By around 525 BC Athens had established a monopoly in luxury wares and in time effectively drove Corinthian and all other regional styles from the marketplace.
The key to Athens's success lay in the quality and variety of the shapes and the wide range of pictorial scenes.
Coarse-ware pottery was produced locally
throughout the Greek world wherever clay was available.
