Restoration
Cannons recovered from the sea are often extensively damaged from exposure to salt water; because of this, electrolytic reduction treatment is required to forestall the process of corrosion. The cannon is then washed in deionized water to remove the electrolyte, and is treated in tannic acid, which prevents further rust and gives the metal a bluish-black color. After this process, cannon on display may be protected from oxygen and moisture by a wax sealant. A coat of polyurethane may also be painted over the wax sealant, to prevent the wax-coated cannon from attracting dust in outdoor displays. Recently archaeologists say six cannon recovered from a river in Panama that could have belonged to legendary pirate Henry Morgan are being studied and could eventually be displayed after going through a restoration process.
