Caring for your bronze patina
Sculpture
The patina is the most fragile part of a bronze sculpture, it consists of a combination of very delicate layers of chemical compounds, pigments and waxes. Maintaining a consistent protective layer of wax over the patina is the key to its longevity.
When handling the sculpture we would advise to wear soft gloves, as sharp rings or watch bands can easily scratch the surface. Handling the bronze with bare hands can transfer oils which over time will decay the wax and potentially effect the patina.
To help maintain the colour and pattern of a bronze patina, we would advise to position the bronze away from direct sunlight and damp conditions.
It is recommended that indoor sculptures are waxed at least once a year, but those that are exposed to high rates of humidity (specifically outdoor sculpture) should be waxed two to three times per year.
Waxing method
Start by cleaning the bronze, avoid using water or any form of detergent simply use a soft dry clean cloth to wipe away any surface dust. For textured areas and crevices where dust has gathered, you can use a clean soft dry brush or compressed air.
Onto the cleaned bronzed, apply a very thin layer of wax with a soft brush. The wax should be left for ten to fifteen minutes to cure and then buffed with a soft cloth or soft brush to the desired finish. The foundry uses Renaissance Wax which is generally available.
Household cleaners and furniture polishes may contain solvents, abrasives or pigments, these can scratch, discolour or soften the wax that is already in place.
