The luminous gold finish seen on many Himalayan bronze sculptures was produced by a technique known as fire gilding. After casting and finishing the bronze, artisans prepared an amalgam of gold and mercury, which was brushed onto the surface. Heating the sculpture caused the mercury to evaporate, leaving a thin layer of gold bonded directly to the metal. The gilded surface was then burnished to achieve a smooth, even finish. Unlike gold leaf applied to the surface of a finished sculpture, fire gilding becomes an integral part of the bronze. The result is a surface that combines the warmth of gold with the precision of the underlying bronze, reflecting both the technical accomplishment of the caster and the finishing skills of the gilder.
