The Four des Casseaux porcelain kiln stands in the Four des Casseaux museum (Musée du Four des Casseaux) on Rue Donzelot in Limoges, Haute-Vienne, Nouvelle-Aquitaine, France. Brick fireboxes open at its base behind iron frames and grates. On the right, long iron tools with hooks lean against the kiln, and round saggers are stacked against the rubble-stone wall behind them. An arch on the left opens onto an exhibition room with display cases. The Four des Casseaux is a so-called round kiln with a reverse flame (four à flamme renversée), unique in the country. It measures 20 metres in height and
