On iron and steel, Torch Patina is designed to be used over a base of Copper Plate Patina to create the torch effect. The uniformity and colors of the patina are determined by the application techniques. Without the Copper Plate Patina base, Torch Patina will turn steel a mixture of black, grey, and rust.
On Bronze, Brass, and Copper, Torch Patina is designed to be applied directly to clean metal.
