Oxidating flame

It even occurs in gold alloys with high copper contents. Oxidation is present in both firescale and firestain.As it generally appears in the form of blotchy patches following abrasive polishing it is seen as a blemish which destroys the clear reflectivity of finished silver surfaces.” So, no clarification there – either on name or spelling – firescale or fire scale. Oxidation (cupric oxide) develops on metal when heat, a metal alloyed with copper and oxygen are all present (hence the word: “oxidation”).When oxidation occurs in copper, on the other hand, the result is a greenish coating called copper oxide.The metal itself is not weakened by oxidation, but the surface develops a patina after years of exposure to air and water.Oxidation can also be a problem for car owners, since the outermost layers of paint are constantly exposed to air and water.If the car's outer finish is not protected by a wax coating or polyurethane, the oxygen molecules in the air will eventually start interacting with the paint.Your kind participation in this program helps me to keep supplying free information like this. This is a very good question and one, of which, I’ve seen various contradictory answers.“Firescale and firestain are often used interchangeably, but technically can mean two different thing….
