HOME OF THE LADY DENMAN - Local history isn't always about the big story - the everyday story of life in the early development of the region can be a fascinating, entertaining and educational journey.

Ravages of time


Beautiful colours
This is one small part of the copper sheeting that lines the hull of the Lady Denman.
Even though the Lady has been out of the water for many years now, the slow release of moisture mixing with air oxidizes the copper and creates these rather beautiful stains.
It’s a slow ongoing process.

Why does Copper oxidize
Copper oxidizes because it is highly reactive and readily loses electrons to react with oxygen in the air. The electro potential of copper is higher than that of oxygen causing a spontaneous oxidation reaction resulting in a green layer of copper oxide. Copper exhibits good resistance to corrosion in urban, marine, and industrial atmospheres.
