Bucchero

It is an ancient Etruscan technique.

Bucchero ware is distinguished by its black fabric as well as glossy. Black surface was achieved through the unique “reduction” method in which it was fired.

In times past, after the leather-hard green ware was arranged in the kiln and the fire started, the vent holes were closed, thus reducing the supply of oxygen required in a normal kiln firing. In the smoke-filled atmosphere of the kiln, the oxygen-starved flames drew oxygen molecules from the iron oxide of the pottery. This process caused the fabric of the clay to change colour from its natural red to black.  The lustrous, shiny, black surface of many bucchero pieces was achieved by diligent burnishing.

 

ブッケロというのは古代エトルリアの技術です。その黒い色と光沢仕上げが特徴です。器を焼くときには、原料となる粘土を「なめし皮」と同じ固さになるまでおき、窯に入れて焼きます。窯で器を焼き始めて、煙が出始めると、窯の蓋を閉じ酸素の少ない状態にします。煙を増やして窯の中の酸素だけで器を焼くためです。そうすることで、粘土の中の鉄と酸素が融合され器の色が「赤」から自然に「黒」になります。

 

E’ un’antica tecnica etrusca. Il Bucchero si distingue dal suo colore nero e dalla finitura lucida.  La superficie nera era ottenuta attraverso un particolare processo di cottura in “riduzione”.

Nel passato, dopo che il pezzo, raggiunta la consistenza cuoio, veniva messo nel forno e quando il fuoco cominciava a svilupparsi si chiudeva la presa d’aria, riducendo così l’ossigeno richiesto in una normale cottura. Nell’atmosfera piena di fumo, all’interno del forno, le fiamme si alimentano con le molecole di ossigeno all’interno dell’ossido ferrico della terracotta.

Questo processo fa sì che l’argilla cambi colore dal suo naturale rosso a nero.  La superficie nera lucida di alcuni pezzi in bucchero era ottenuta da una diligente brunitura.
