We use C38500 Architectural Bronze for vitually all purposes although other Bronze alloys can be used including C22000 Commercial Bronze, C28000 Muntz Metal and C23000 Red Brass, and Aluminium Bronze where required.
Bronze is a highly decorative material with a naturally gold colour when cut or cast, it gradually acquires a 'patina' of darker oxidation on exposure to air, or green copper salts in maritime envoronments. This appearance can be artificially accelerated by a process known as 'patination' so that newly made items can be given an appearance of age.

Bronze, brass and copper can be chemically treated to make the surface look as if it has been exposed to the elements for many years. A variety of different effects can be created by the use of different chemicals, waxes etc., a process known as 'patination'. Some typical effects are shown in the chart below (pictures courtesy of Copper Development Association).
