The sculpture before treatment. The polluted environment had led to a mottled black surface appearance

Remnants of old wax on the surface had absorbed pollutants and become blackened. Where wax was weathered away the underlying bronze had a dry green appearance

Henry Moore
'Oval with Points' 1968
This monumental bronze sculpture is owned by Hongkong Land and it is displayed outside the Landmark Building in Central Hong Kong. Early photographs show that it originally had a variegated watery green patina, with a member of staff at Hongkong Land commenting that he remembered it was ‘like a piece of jade’ when it was first installed. Over the years the high levels of humidity and pollution in Hong Kong had caused the surface of the sculpture to become blackened and unsightly. Together with our fellow sculpture conservator colleagues from Two Sticks in New York we were asked to undertake a treatment of the sculpture to improve its condition.
The sculpture was first cleaned with steam to remove surface soils and traces of wax. Small areas of missing green patina were retouched using a selection of cold patina recipes used on Moore’s sculptures and collected through past research in order to integrate the overall appearance. A clear wax was then applied to the surface of the sculpture to provide some protection from weathering.
