Chaux de Coquillages de La Rochelle
The production of lime from burned oyster shells — a building material tradition unique to the Atlantic coast of France, where the abundance of oyster shells from centuries of oyster farming provided an alternative to limestone for lime production. Shell lime (chaux coquillière) produces a purer calcium oxide than many limestone deposits and has been used for centuries in the white-washed architecture of the Charente-Maritime coast and the Île de Ré. The calcination of shells requires a lower temperature than limestone and produces a more reactive lime.
