Metallic surfaces and details are very popular in interior decoration today. They are widely used to decorate furniture and accessories. The so-called aged metal was especially fond of. That is, not a smooth shiny surface, but a rough one, with different color shades. Such decorative elements give the interior or garments a certain solidity, passing the test of time.
Necessary
- - active acids or bicarbonate soda
- - Nitric acid
- - drying oil
Instructions
Step 1
Modern chemistry offers a fairly large number of methods for decorative metal processing. Many recipes have been known since ancient times. Choose a method depending on the desired results, as well as the type of metal you are going to decorate.
Step 2
Before starting to work with the material, clean its surface from any contamination. The results of your work will largely depend on how carefully you go through this stage. The product can be gently baked to get rid of resin residues or any other impurities. If you are going to work with brass or copper alloys, bleach them in a weak solution of sulfuric acid, and if you are going to work with iron, use sulfuric acid. For aluminum products, bicarbonate soda is well suited. After processing items, rinse them well, clean with a metal brush. Now proceed directly to finishing.
Step 3
To be acidic outdoors. You need a cotton swab to work. Wrap it on a wooden stick and use it to apply nitric acid or a solution of it to the metal surface. After the reaction is complete, heat the object and continue heating until the evaporation reaction stops.
Step 4
The color of the surface will depend on the concentration of the acid, the time the metal surface is treated, and the degree of heating after processing.
Step 5
When working with iron products, immediately after cleaning the surface, apply drying oil on them. Then heat to 300 or 400 degrees. If you use an oven, the surface tone will be more uniform. If you want to brighten the surface, use nitric acid.
Step 6
If you plan to age or simply decorate the aluminum surface, prepare kerosene or soot for the procedure. This is the best way to highlight all the features of the relief and give the surface originality.
