Green Patina is supposed to be healthy food for your horses. Also - The patina might be ok, What about too much copper?

To oxidize copper and achieve a green patina, you can expose the copper to a combination of oxygen, moisture, and acidic substances like vinegar or saltwater. This process will create a chemical reaction that forms the green patina on the copper surface.
light green color (called a patina)
When copper is exposed to air and moisture, it undergoes a chemical reaction that forms a green patina on its surface. This patina is mainly composed of copper compounds such as copper carbonate and copper hydroxide, giving copper its distinctive green color.
To achieve a blue patina on brass, the process involves applying a solution of ammonia and salt to the brass surface and allowing it to oxidize over time. This creates a chemical reaction that results in the desired blue-green color. The brass can also be heated or treated with other chemicals to enhance the patina effect.
The time it takes for copper to develop a green patina can vary depending on environmental factors such as humidity, temperature, and exposure to elements like air and moisture. It can take anywhere from a few weeks to several years for the green patina to fully develop on copper surfaces.

To achieve a green patina on copper, you can use a mixture of vinegar and salt to create a chemical reaction that oxidizes the copper. Simply apply the mixture to the copper surface and let it sit for a few hours or overnight. You can also expose the copper to the elements, such as moisture and air, to naturally develop a green patina over time.
Copper can be aged to achieve a green patina by exposing it to air and moisture over time. This natural process, called oxidation, forms a layer of copper carbonate on the surface, giving it the characteristic green color.
Copper turns green when exposed to oxygen and moisture over time, forming a patina. You can accelerate this process by using a mixture of vinegar, salt, and ammonia to create a green patina on copper surfaces. This mixture can be applied to the copper and allowed to sit until the desired level of green patina is achieved.
To quickly turn copper green, you can use a mixture of vinegar and salt or a commercial patina solution. Simply apply the solution to the copper surface and allow it to sit for a few hours or overnight to achieve the desired green patina.
