Project Information

The 18th century lead sculpture of and African slave holds aloft a Delander sundial. The weight of the sundial in addition to the failing armature had caused the figure to slump and distort.

Panels were cut into the figure to allow access to the failed armature, this was removed along with the old fill material. The distorted sections were reshaped and a new stainless steel armature made to fit the reshaped figure. All of the cracks and splits were repaired and the access panels welded back into position.

Historical records tell us that the sculpture was originally finished to imitate a bronze. Paint samples were taken from a contemporary piece which still had its paint system intact; the interior lead sculpture of Andromeda, located at Osterley Park. The paint system consisted of a grey base coat followed by two coats of brass filings which were mixed into an unknown medium and tinted with iron oxide yellow pigment, the top coat was an oil that had been tinted red-brown. These layers were carefully built up over time with particular attention being paid to the high lights and low lights to emphasise the modelling in the piece.
