Buddhist Temple Gold Leaf Application (Kinkaku)

金箔押し (Kinpaku-oshi)

Kinpaku-oshi (金箔押し — gold leaf pressing) is the technique of applying gold leaf to wooden Buddhist sculptures, screens, and architectural elements using urushi adhesive (漆箔 urushi-haku) or sizing (膠箔 nikawa-haku) as the bonding medium. The urushi-haku technique — applying gold leaf to urushi-coated surfaces — is the most demanding: the urushi must be at precise tack when the gold is laid, and the gold must be pressed with a deer horn burnisher to bond completely without tearing. The Kyoto tradition is notable for its application to the intricate carved surfaces of Buddhist sculptures — gold leaf must conform to carved drapery folds, facial features, and decorative motifs without tearing at convex edges or collapsing into concave recesses. The technique requires calculating how to cut each gold leaf sheet into sections that can follow the curved surface without overlapping (which would show as double thickness) or gapping (which would show as bare urushi).
