The easiest way to burn steel in different shades

The easiest way to burn steel in different shades

Bluing steel allows you to create a protective coating that prevents corrosion, which also has good decorative qualities. If done correctly, it has greater durability than paints, therefore it can be used on rubbing surfaces. Let’s consider how you can make bluing at home in various shades: golden, blue and classic black.

What you need:

  • gas-burner;
  • solvent;
  • container with water;
  • container with mining.

Bluing process

The bluing blank must be well sanded to be smooth and degreased with a solvent. Then the part is hooked with a wire hook and evenly heated with a gas torch. In places where the metal is thickened, it takes longer to heat it.

If at the moment of appearance on the steel of a golden tarnish color, you dip it into water, then such a noble bloom will be preserved.

It is the thinnest bluing layer, which is quite easily removable, with excellent decorative qualities. If you cover such a blank with transparent varnish, then it will look beautiful and will definitely not rust.

If you heat the workpiece longer, until blue begins to appear under the torch of the soldering iron, and also cool it in water, we will get a more durable and very beautiful bluing. However, it also needs additional varnishing.

The most resistant bluing can be achieved by heating the part to a uniform gray tarnish color, so that it appears over the entire surface.

Then it must be pulled out and heated with a burner so that the oil finally bakes and reacts with the steel. As a result, the workpiece will become matte black. If you re-dip it into the mining and dry it with a burner, then the color will become deeper. This bluing layer does not need varnishing. Metal will not rust through it.

When bluing, it is important not to overheat the part more than to a gray tint. Otherwise, the metal will loosen, become softer and lose its original properties.
