Bronze is a similar metal alloy to brass. Both have about 60-70% copper content with the rest mostly zinc (for brass) or tin (for bronze). Tin is considerably rarer and more expensive to extract than zinc so bronze is considerably more expensive than brass.
Despite this, solid bronze has an indefinable quality about it. Maybe it's the subtle colours you can detect close-up, or it's longevity, or it's provenance as man's first technological metal? The result is a range of ironmongery which oozes class. These products have a light antiqued finish which is not lacquered and can be polished to a pinkish golden shine or left alone to form a natural protective verdigris patina.
