Jean Darcet

Jean d'Arcet or Jean Darcet was a French chemist, and director of the porcelain works at Sèvres. He was among the first to manufacture hard porcelain in France and helped reduce imports and establish the ceramic industry at Sévres. He is also remembered in Darcet's alloy, a mix of bismuth, lead and tin that melted easily and was used for low-cost dental filling and other applications. His son Jean-Pierre-Joseph d'Arcet (1777-1844) also became a chemist.
