During the reducing phase of the three-phase firing sintering of the iron-rich "clay paint" led to a shiny black glaze.
The glaze, originally in the form of a fine grained clay paint, was added on with a paintbrush on the wheel, or by dipping.
Within about a hundred years, during the 5th century BC, black-glazed wares replaced the previously popular red-figure pottery from the Mediterranean markets.
Since the Hellenistic periods, non-Greek workshops also produced it, usually just serving local or regional markets.
In recent years, the importance of the type in modern research has increased considerably, especially in the contexts of culinary habits, regional contacts and trade links.
