A World Built of Oyster Shells

Earlier this week, I wrote about the historic use of oyster shells for constructing roads on the North Carolina coast. But coastal people didn’t only use oyster shells for road building. Particularly before the Civil War, they also used oyster shells as an important source of lime. Burnt down in kilns, an incredible tonnage of oyster shells was used in making cement, mortar, bricks, wall plaster and whitewash.
