Facet varnish is not a patina but an antique effect based on cracking.The liquid is a special varnish that gives the wood a light yellow or golden hue inherent in antique oak or ash.For the gilding effect, the base is the natural color of the wood – the same oak, for example. Usually, you get light brown, reddish or gold shades in this way. A thick patina is in the form of a paste, usually two-component.The latter are purchased in construction stores. It is necessary to combine chemical and mechanical methods for the best effect. However, on woods of high density and hardness that are very insensitive to water – such as oak – a white or dark patina indicates antiquity.Īrtificial patination is often done on classic living room furniture because it is difficult to get a natural patina on the furniture. The patina on wood is often not a good thing, as it appears when it is affected by fungus or rot. The color, in this case, can be absolutely any – from light gold and white to black and may include shades completely untypical of natural material. This is a kind of imitation created with the help of conventional stains and paints – for example, acrylic. You can also distinguish the group of decorative patina.Such coatings are less durable and more porous than the noble film but protect the metal. Artificially made patina is formed much faster due to specific chemical reactions.It is necessary to get rid of such a film. The second – loose and from moisture metal will not protect. The first has a dense structure and protects the metal from corrosion (e.g., green patina on copper). It is divided into a noble patina and a wild patina. ![]() The natural patina appears during the oxidation of the metal in the atmosphere.It is obtained, of course, in other ways. As a result, an artificial patina was born. After all, through transitions of color, this noble patina emphasizes the beauty of the carvings and forges, volume texture, or indicates the object’s age, which unwittingly translates the living room furniture or other product into the category of rare or at least antique. Strangely enough, the presence of such a patina, if the coating does not affect the characteristics of the product and does not destroy it, not only is not destroyed but is often welcomed. In other cases, the process stretches for many years – as in the case of green patina on copper, silver patina (blackening), and so on. In some cases, the effect is speedy – for example, rusting of iron. To some extent, any material except gold and platinum interacts with oxygen and moisture in the air. Today, patina is also an aging effect, so fashionable when decorating furniture and kitchen utensils. Later, it also referred to a patina that appeared overtime on metal or wood surfaces. I encourage you to experiment with LOS and colors.In its original meaning, patina meant an oxide film on a copper item of green (malachite) or bluish (azurite) color. And, if one is not happy with the color, one can remove the patina by (assuming no gems) a quick trip through the kiln or (if there are stones) lots of rubbing. However, I have had patina colors remain unchanged for years. Sometimes the change is for the better, sometimes not. One warning about LOS-based color on silver: the patina is not static. I put a moonstone in the tiny pendant, letting the pale stone contrast with the dark background. That leaves the pieces very shiny, while, leaving the patina in crevices. The very small pendant got a longer one still.īecause the person I was making these for likes ‘shiny’ jewelry, I removed most of the patina with a polishing cloth. The pendant with the geometrical design got a longer treatment (purple). ![]() The earrings with the botanical design got a longer treatment (bronze). I gave the earrings with the birds a very quick dip (gold). The pendant in the middle has a bezel cup. Very occasionally, red or turquoise will appear.įor my example, I start off by showing you some simple pieces just out of the tumbler. A long soak will yield gun-metal gray, and a slightly longer soak will yield black. A bit more than that will yield a bronze/brass color. In short, colored patina really seems to be up the to will of the patina gods.Ī quick dip will give a gold-like appearance. I give no proportions because, in my experience, controlling proportions and temperature does not give you as much control as you would expect. To produce a solution that will induce color on silver, add a pinch of salt, a dash of clear ammonia, and LOS to warm water. However, with silver, LOS can also be used to provide other colors. I’m going to take this opportunity to discuss how one puts color on silver with LOS.įirst of all, LOS can turn silver (or most other metals) black. ![]() To make it a bit more interesting, I thought I would add color with Liver of Sulphur (LOS). After the migrating snow goose, I felt like doing something simple.
