One cannon being readied for conservation at Texas A&M University.A team of Texas A&M students work swarm over the cannon to carefully remove the rocky concretion.
 
 
A pair of Texas A&M marine archaeology students set the cannon on its side to remove the rocky concretion. The wooden base of the cannon was eventually fully exposed after carefully removing the rocky concretion. Shown upside down here, the t-shaped object projecting from the base fit into a slot to help sailors control the cannon's recoil during firing. 
 
 
A Texas A&M student at the conservation research lab uses a small air-powered tool to carefully remove the rock and sand shell coating the cannon. The cannon's wood and metal parts must first be exposed, then separated so they can be treated to resist corrosion. 
 
 
With the rocky concretion nearly gone, the cannon must be kept wet to prevent more corrosion. The cannon with the rocky concretion removed. It is never allowed to rest on the fragile wooden base (probably oak).
 
 
A close-up detail of the cannon's rear end. A large screw fit into this hole, allowing the sailors to point the cannon up or down to aim during firing. Exciting: a mark on the cannon's surface that looks like a broad arrow, indicating the cannon probably came to the US from the British Royal Navy. The young US Navy bought many such arms from overseas in the early 19th century.
