BLACK PATINA FOR SOLDER 250ML
Black patina is used to blacken solder. After washing and cleaning your copper foil project, scrub with fine steel wool, and then using a brush or a rag generously apply the patina. Continue to brush on the patina to achieve the desired colour. Wash off in cold water, dry and apply a wax finishing polish. It can also be used to darken solder joins on lead prior to puttying.
