Use Procedure

Lily Black Oxide is used as supplied in a temperature range of 285°F to 295°F for approximately a five minute dip. The ability of Lily Black Oxide to apply a "bluing" to steel is temperature dependent. As the temperature falls below 285°F more product must be added. As the temperature rises above 295°F water must be added. Cast iron parts blacken best at 285°F, while steel parts blacken best at 295°F.

Prior to the black oxide process, parts should be cleaned and thoroughly rinsed to ensure that the work is properly prepared. After the oxide process is complete, parts should be rinsed in a roiling boil, clear water rinse to remove the excess chemical. If desired parts can then be dipped in a water displacing corrosion inhibitor, Metgard WDS, for maximum corrosion protection.
