Patina, Green Verdi, 444

Green Verde #444 is a chemical solution that speeds up the natural aging process of Copper, Brass, and Bronze and provides a beautiful Green Verde Patina directly on the surface of the metal. This process does not require previous treatment with antiquing solutions. However, the metal needs to be cleaned and free of grease, oil, sealers, waxes, and/or paint. Some specific applications include lighting fixtures, furniture, jewelry, and other artistic creations and this process is especially popular for green copper patina roofs and gutters.
Procedures:
Parts must be free of grease, alkalinity, or acid when Green Verde 444 is applied. Parts must be thoroughly cleaned and deoxidized prior to blackening. Cleaner 104 is recommended for removing heavy oils and oxidation. Do not use petroleum-degreasing solvents that leave a residue on the surface. Rinse thoroughly with overflowing cold water to remove residual cleaners and dust. It is important that alkaline cleaners are completely rinsed off prior to blackening.
