In the following example, the silver solder inlay stands out in a copper piece with a dark green patina. Silver is only superficially affected by this chemical reaction, so it can be used in combination with copper and provide some contrast. Once the surface of the metal is clean, avoid touching it (hold by the edges or make a handle with fishing wire).Ĭopper is best suited for this type of patina, although brass, a copper alloy, will work up to a point with much less dramatic results. This is not just corrosion but a protective barrier that prevents further deterioration of the metal underneath. Pumice works well, but scouring cleaning products like Ajax or Comet, for example, will do the job. Copper patina is a layer of various compounds such as oxides, carbonates, sulfides, or sulfates that develop on the surface of copper or copper alloys, such as bronze and brass, as a result of exposure to atmospheric elements. The metal must be thoroughly cleaned (free of grease and oil) to ensure the proper action of the chemicals. Give it a try and let me know.Material used are basic salt and ammonia, things y. And like last time, I have chosen basic recipes that can be used easily in a small studio, with limited equipment and common household products (vinegar, ammonia and salt). Today, I finally have that Force Patina tutorial Ive mentioned a few times. This time, I will focus on greens and blues. In a previous post, I shared a few simple recipes for creating red patinas on copper. There are countless options available to metalsmiths when it comes to metal patination, especially with copper and brass. So, let’s get to it before I surrender to a “less colourful” work routine. As the last lilacs begin to fade, so does my enthusiasm. But I also know this surge of optimism (and over-confidence?) is usually short-lived. It makes me want to start new projects – something “new” and fresh, something well… green of course. I always find this influx of renewed energy quite contagious. As I observed the beginnings of patina spots building after concluding my first shave, thoughts of fun experimentation began to percolate in my mind. Days are getting longer, trees are greening and flowers are blooming. Since brass is very soft, the matte bead blast finish comes away in no time, and a final mirror-like shine readily presents itself, as is the above.
