Patina is an artificial mixture of different elements that contain cryptocrystalline aggregates of calcite with occasional foraminifera (powdered or partially dissolved chalk), ferruginous clay, charcoal, and some tiny specks of gold. That’s a real mouthful.

To put it more simply, Patina is the thin sheen that slowly develops over time on leather, metal or wooden goods caused by natural forces such as exposure to the sun. The term can refer to fading, darkening, or signs of aging.

Think of how leather looks after being left in the sun for a long time. Patina improves the natural appearance of the leather. This type of beauty forms with age over time. In this blog, we will learn more about this phenomenon.


Patina Finishing

What Is Patina Finishing?

Do you want your item to look aged? Patina is the chemical process that happens over time, making the piece look old. Metal will appear darker as it ages. You may not have time to wait around while your item ages, so artisans kick-start the process in various ways.

Have you ever stopped to admire a copper statue or stunning piece of art? Bronze, silver, and brass naturally tarnish when exposed to water and natural elements such as air.

This turns the shiny copper to a darker brown with varying tones. If left alone, it will eventually turn a stunning turquoise green. A perfect example is the famous Statue of Liberty.

A green or brown film starts forming on the object because copper is known as a living metal.

The main reason that it is so popular is that it is aesthetically pleasing. You will find Patina in architecture and many famous buildings.

How Is Patina Metal Different From Other Metallic Paint Finishes

We already know that patination is caused by oxidation or weathering in metals, stone, and wooden furniture. They form Patina to protect themselves against damage caused by corrosion.

Some fantastic paints on the market may look great, but they will always have a different feel than Patina.

Paint is applied as a solid color; conversely, Patina is a chemical reaction that occurs over a long period.

The color becomes a part of the metal itself. Metal can reflect light, and depending on how the light hits it, you will see various colors as you move around the object. Paint will always have the same color and tone.

Paint has come a long way, and some fantastic products are available, but none will compare to the natural beauty of patinas.

Metals that can be patinated:

  • Copper
  • Brass
  • Bronze
  • Zinc
  • Steel

Patina finishes are perfect for achieving rustic, decorative textures in floor tiling, metals, brass, and even wood. It can be used on most metal products to achieve a stunning natural oxidized metal effect.

Patina can be used for sinks, tubs, table tops, light fixtures, mirrors, knobs and pulls, towel bars, backsplash murals, and much more.

Aged copper finishes include:

  • Ayrshire: Relaxed, light copper patina with small specks of verdigris

Patina is usually found in buildings, statues, and other art pieces but has various practical uses.

  • Brass/Bronze: Add warmth to any room. The yellow and gold colors work well together, especially when patinated to a dark tone and highlighted with a light burnish to highlight the original color. It is found mainly in the kitchen on brass or bronze hood ranges. It can also be used on bronzed frames, handles, hinges and other hardware
  • Polished Brass and Antique Brass: It is wonderfully versatile and has its own inherent beauty due to the golden sun-like color. If polished, it takes on a mirror appearance. You could often find this effect in the Victorian and Edwardian eras on furniture, doors, and windows and in the car industry
  • Copper Patina: Copper reacts much like brass and can be found in copper cooking pots, plumbing pipes, and old building roof sold building roofs.
