The ambitious project to restore Large Figure was completed in three distinct stages, within a tight six-week schedule.
The first stage involved the removal of the degraded lacquer and areas of intense oxidation to reveal the base metal. To remove the lacquer, coarse 60 grit sanding pads were used, followed by finer sanding pads to produce a more even surface.
Once the lacquer had been removed, stage two - the repatination itself - began. A chemical patina of dilute potassium sulphate was applied in thin layers with a cloth to produce a warm, gold-brown colour.
Finally, in stage three, a mixture of clear and neutral beeswax diluted in white spirit was applied to the surface. The white spirit was then allowed to evaporate, and the surface was polished with a lamb's wool cloth.
The beeswax coating will protect the patina while allowing it to develop naturally over time. This protective barrier can be assessed and reapplied as necessary, in accordance with the Foundation's current practice.
