What is the patina on carbon steel?
Magnetite turns carbon-steel knives a charcoal gray, giving them what we call a patina. Both types of oxidation occur when carbon steel comes in contact with oxygen and moisture (reactions that are sped up in the presence of salt). Magnetite will form when exposure to oxygen and water is limited.
What is patina on a knife blade?
A patina is a natural protective layer on carbon steels that protects the blade from further oxidation and gives it a look of rough finish. It is produced by the oxidation of steel surface and this process is even quicker if a knife comes into contact with various acids.
What does mustard do to steel?
Applying mustard to the surface of a carbon steel knife forces a patina on the surface. Mustard is slightly acid and, when slackened with a little water and applied with bubble wrap to give some texture, leaves a pleasing mottled patina on the surface.
