Labu Sayong is a gourd-shaped water pitcher thrown from Sayong river clay in a single Perak village. Its black is not a glaze but a firing accident made repeatable: bisque at 850–900°C, cool to 450–500°C, bury the still-hot pot in rice husks, and in five minutes the smothered fire lays carbon across the burnished skin.

The design system follows that logic. A matte carbon ground, a graphite sheen where the surface was polished before firing, unsmoked clay breaking through in brown, and stamped motifs held in strict horizontal bands round the neck and shoulder — never scattered, never painted on.
