The Vast Explorer
To map the Whydah's debris field, Clifford towed a magnetometer behind his ship, the Vast Explorer. After finding the artifacts, divers made a grid of the excavation area in one-inch squares.

Concretion
When concretions are brought to the surface, they are immediately placed into a tank of freshwater.
Anywhere from 2 to 4 weeks later, they get moved to a different tank that is filled with a chemical solution.

Sun King Pistol
The value of radiographic imaging in determining what was inside of a concretion became apparent almost immediately.
This concretion was found to house a pistol, a favored weapon with pirates.

Tea Kettle Conservation
A tea kettle, in the final stages of conservation, sits in a chemical bath. Conservationists will later us brushes and small picks to clear away the final debris.
This tea kettle has a special fitting on the bottom to allow it to sit in the stove so that it wouldn't be tipped over while at sea.
