This topic is essential to the artists that contribute to the game. It can help them to properly understand the nature of the material that they are working on, in order to properly depict them in the game. This topic will serve as a baseline for the discussion about the metallurgical history of the respective factions which are playable in 0ad. I really encourage the information junkies around the community to participate in the discussions in order to create a useful reference which the community artists could use. Thank you very much!
