摘要：
The present invention relates to a method for preparing an artificial patination material to substrates, preferably made from copper or copper alloys and a patination material. The raw material is a copper salt, which reacts with an alkali metal hydroxide. The precipitate is dispersed with powerful mixing and an addition of a dispersing agent. An oxidative agent like manganese dioxide is used, and carbon is used as an agent for catalysing natural patina forming. Metal compounds are used to achieving desired colour and/or colour tinge. The invention relates also to the corresponding patination material.
