Raw Bronze (RB).
Raw Bronze is the purest form of bronze, an alloy of copper and tin.
Raw Bronze is corrosion free, so it doesn’t require a protective layer. This rough form of bronze comes with warm, copper-like colours. To offer the bronze its rough look, a special technique was developed. The casting remains are removed, but the item is not polished. After some time, the bronze will have a shiny look, since the metal will be polished naturally.
