Firearm Bluing

What is Bluing?

Bluing is a passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish. It is used to improve corrosion resistance and reduce glare.

Types of Bluing

This is the most common method, involving a series of hot salt baths.

A simpler method using cold solutions, often for touch-ups.

An older method involving controlled rusting and carding.

What Are The Benefits of Bluing?

  • Improves corrosion resistance
  • Reduces glare and reflection
  • Enhances aesthetic appeal
  • Can increase the value of a firearm

The bluing process involves several crucial steps.

  • Cleaning: Remove all oils and contaminants from the surface of the steel.
  • Polishing: Smooth the surface to the desired finish.
  • Bluing: Apply the bluing solution through either hot or cold methods.
  • Neutralizing: Stop the bluing reaction with water or other neutralizers.
  • Oiling: Apply oil to protect and seal the blued surface.

To maintain the blued finish on a firearm, regular cleaning and oiling are recommended. Avoid harsh chemicals that can strip the bluing and always store the firearm in a dry environment to prevent rusting.
