Florentine bronze

Florentine bronze is a modern term for a type of bronzed metal.

Prior to 1828, the primary artificial bronze used for copper and copper alloys was antique green of various shades. A metal colouring called "Florentine bronze" was introduced by a French man named Lafleur around 1828 and soon became popular.^[1] A variation, Florentine fremé ("smoked" bronze), was introduced by another French man named Camus in 1833.^[2]

The alloy is usually formed as a mixture of aluminium or tin (<10%) and copper (>90%). Currently no chemical formula for Florentine bronze has been made as it is an alloy which is not standardised (in proportions) worldwide.^{[citation needed]}

"Florentine bronze" bears no relation to the 16th century bronze reductions of full-scale sculptures that were made in Florence after models by Giambologna and other Mannerist sculptors, to satisfy a collectors' market.
