Notes

Pomponne Name of an alloy developed by goldsmiths Turgot and Daumy, established in the Hôtel de Pomponne, rue de la Verrerie in Paris, who received, in 1785, from Louis XV, King of France, a Privilege of manufacture. The composition of the alloy, based on copper and zinc, is not well known and was used to imitate gold and silver. Until that date all imitations of these metals were prohibited in France. Antique Pinchbeck or Pomponne jewellery, like all plated jewellery can’t be repaired because, by heating, the two metals are mixed and the gold layer disappears. Christopher Pinchbeck (c.1670-1732), London watchmaker, creator of a zinc and copper alloy bearing his name, the Pinchbeck that looks like gold. He has a son of the same name (1710- 1783).
