    What Does Blue Green Color Mean in My Sink/Shower

    Introduction. Most corrosion problems show up as blue green staining. The stain is copper deposited from the corrosion of the water piping and fixtures. The corrosion will eventually cause pinhole leaks in the water pipes. Pinhole leak caused by the corrosion of copper pipes. There can be a number of causes for the corrosion.

  • Why Does Copper Turn Green Over Time? (Patina Chart)

    Why Does Copper Turn Green Over Time? (Patina Chart)

    Copper naturally turns green over time as it reacts with oxygen in the air – a chemical reaction known as oxidation. The green colour is simply the natural shade of the patina that forms over the copper surface; the patina protects the copper from deterioration and creates a light bluishgreen facade which can be seen on many copper rooftops and copper structures.

  • Why causes copper to turn blue instead of the expected green?

    Why causes copper to turn blue instead of the expected green?

    When copper is oxidized by a combination of air, humid and finely divided acid and salts in the air, then a socalled patina of copper is formed. This is a basic copper (II) carbonate/sulfate mix, which has a cyan color. The reason that the color ...
