The oxidising agent stimulates the natural oxidation process of metals, creating effects of porosity and authentic rust. It is particularly useful for improving the adhesion of paints on brass photo-engravings. Note that some natural rusts can be toxic, so it is advisable to apply a varnish after oxidation to seal the rust and avoid direct contact.
This product is designed to rust the pure metallic pigments in our range in a very natural way.
