Hervé Rousseau uses stoneware, made from Beauvaisis clays, which he works directly by hand. He favours direct-flame firing in a Noborigama kiln, consisting of two chambers, inspired by the traditional multi-chamber dragon kilns that appeared in China probably during the Shang dynasty (1600-1046 BC). The artist places his pieces in different parts of the kiln so that zones marked by oxidation and others by reduction appear upon unloading. The results are powerful shapes, exhumed from the block of clay, recalling the shape of fossils, such as this large wing whose flight feathers are hollowed out by the impact of the ceramicist's hand.
