After heat-treating the resulting slurry, miners could separate the mercury and gold for processing. Even artisans have used mercury and gold to create stunning effects. Ormolu – a type of mercury-gilding – involves coating a piece (usually porcelain) in an amalgam, then using extreme heat to burn away the mercury, leaving a layer of gold.
