#Patina metal how to#

To demonstrate how to create patina, we will apply some sim-ple household chemicals to a small piece of 20-gauge bare steel. Individually, they are benign compo- nents, but once we put chemistry to work, they work with and against each other to give us great rusty results! Vinegar is a mild acid, ammonia is a common household cleaner, and table salt has obviously been around for millennia as a spice and flavor enhancement. This will create the appearance that a particular part has been rusting for a very long time.īy using basic chemistry and common products, we can create a cool rusted surface that looks as if it has been rusting for years. Take the warning labels on these household items seriously! Have fun with this, but please stay safe. While we show you how to mix certain simple chemicals together to gain an effect on metal, certain reactions could occur if care is not taken to be safe. Please take all precautions to maintain a well-ventilated area and to use appropriate safety equipment while mixing chemicals.

This Tech Tip is From the Full Book, HIGH PERFORMANCE AUTOMOTIVE COOLING SYSTEMS. If you then have a container of ammonia sitting beside the coated parts, the fumes will affect the sprayed solution and set in motion a chemical reaction that will deteriorate the outside surfaces of these metals very quickly. When you add a couple of tablespoons of salt to a cup of a mild acid, such as vinegar, you create a very corrosive solution that can then be sprayed onto bare metal products, such as fasteners and hinges. You can speed up the process of rusting with acids and salts to create the appearance of natural exposure.Īdding an acid to metal produces hydrogen gas, which promotes faster oxidation. Copper oxidation (such as the green patina on the Statue of Liberty) bonds to the base metal and forms a protective layer on top, creating a chemical seal against the outside atmosphere and slowing or stopping the deterioration process. In most cases, the oxidation process will deteriorate completely through the metal, the top layer will flake off and expose underlying iron, and it will eventually disintegrate completely. Oxidation is not always rust colored on iron. A simpler, more natural, and more passive approach to accelerated rusting simply involves exposing the metal to chemicals and letting time and chemistry take its toll, although not the decades-long time frames that nature demands.

We simply don’t have another 50 or 60 years to let vehicles ferment and degrade, so we must come up with techniques to accelerate time or fool the eye to give the appearance that we have. Copper or bronze will slowly change outer coloration and develop beautiful patina over the years. Thick iron beams will remain strong for hundreds of years while steadily rusting. These processes take a lot of time in nature. The act of taking a decades-worn vehicle and enhancing the deteriorated metal and paint has become a genre of custom car creation, and it bears acknowledgment and legitimate praise in the industry for expanding the way cars and customizing can be appreciated. Rusty metal is the foundation for many automotive fauxtina (man-made patina) projects, and the aesthetic foundation of the entire “Rat-Rod” style of custom car building in the automotive aftermarket. Metal is the primary substrate in which we may want to instigate rust to create a patina effect.
