Giannis vs Polinik on the color of bronze :)

Depends on the circumstances. In a wet environment such a patina can appear within a few hours. The patina cannot really be preserved in a specific state, it will always change to a darker tone, until it is saturated. In Antiquity bronze and brass items were often intentionally patinised, e.g. with egg, or with acids. This was shown by F. Willer on the finds from the Mahdia shipwreck. Dark brown and even black tones were created this way. This is also possible for armor etc., but there we lack investigations in this regard, unfortunately. Future will bring up some results, hopefully.
