Rust | patina | is that rust is (figurative) to degenerate in idleness; to become dull or impaired by inaction while patina is (figurative) a gloss or superficial layer. Is that rust is the deteriorated state of iron or steel as a result of moisture and oxidation while patina is (originally) a patent, flat type of dish.

(en noun) The deteriorated state of iron or steel as a result of moisture and oxidation. The rust on my bicycle chain made cycling to work very dangerous.

A similar substance based on another metal (usually with qualification, such as “copper rust “). (figuratively) To degenerate in idleness; to become dull or impaired by inaction.

Whether you’re fixing discolored surfaces or trying to achieve a certain cosmetic alteration, there are plenty of chemical processes associated with common household metals. Rust, tarnish, and patina all have numerous differences that can make doorknobs, tables, wind chimes, and many other items look completely changed.

Rust starts to chip away and corrode the metal surface, creating porous cracks and hazardous, sharp edges. Tarnish happens to copper, brass, aluminum, silver, and a few other metals.

Both processes (including patina as well) can’t occur on most solid iron surfaces. Patina and tarnish don’t cause any harm unless you’re using chemical sprays to artificially change the color.

The key takeaway from this section should be that rust is never a good thing, but the others are great when controlled. Oxygen and sulfur dioxide are the two primary non-metal compounds that cause tarnish on metals.

When they interact with one another, the result is a slight deterioration paired with a strong color adjustment. It breaks the outer portion of the metal, making it quite a bit weaker than it normally would.

Remember that there are certain chemicals found in modern makeup that can cause your jewelry to tarnish as well. It could be a result of your earrings resting on the side of your face or makeup touching and coating your necklace when you remove it.

Whichever cause may be, non-natural makeup is the enemy of silver, copper, and brass jewelry. All you have to do is spray on the solution, let it sit for 30 seconds, and wipe it off with a clean cloth or sponge.

You could also combine forest green, light brown, and copper-tone paints to mimic the appearance of tarnishing without altering the chemical compound of the metal. The oxygen in the air, combined with old metal, causes patina fairly quickly.

Acidic rain carries all the necessary compounds to interact and change metals. Finally, natural aging changes the appearance of many types of metal.

The only notable difference is that the colors are a bit unique from one another, and the materials that they form change the names. Also, rust is grouped together in large blots, whereas tarnish and patina usually cover the entire surface.

Rust typically eats away at the metal, leaving cracks and indents. All types of tarnished metal can be polished, shining the highlights to make it look much more visually appealing.

Never let moisture settle on metal for too long, and make sure you clean the surfaces regularly. Close examination will show that they have unique colors, textures, and chemical compounds that cause them.

“It appears in orange with a flaky texture, and is generally considered an eyesore, but in the right circumstances can give an object a look of age and authenticity,” she explains. While the surface of more recently rusted objects can sometimes be flaked off, Shay Iron of Heirlooms Antiques & Art says that if it's been a while, you might be stuck with it.

By Shawn Over, DesignandBuildwithMetal.com I have a friend who bought a beat-up Model T truck a couple of years ago and did a great job of bringing it back to running condition, as he’s done with other old autos. And after having more than a year to get used to the idea, I’ve come to agree that it can be a good practice in cases where the sheet metal hasn’t rusted through and there are no significant dents.

We all know many famous architectural landmarks that fit this description among countless worldwide examples on government buildings, college facilities, museums, homes and other structures. To say that the same desirable patina definition can be applied to the red rust on autos would have seemed like a stretch to most of us five or 10 years ago, and it probably would have been considered an abomination in decades before then.

But times change and so do opinions, which leads me to ask this: If a rusty old car can be considered a thing of beauty, can those same aesthetics be applied to decades-old metal roofing and wall panels that are showing red rust ? If you're interested in seeing some great examples of natural metals used in roofing, wall and rain ware applications, check out dozens of projects in our Design Solutions section.

The metal is still very smooth and you can really only see it in really bright light. I've done google searches and posted in a few other forums but everyone just freaks out and declares they would never strip the black paint off the rifle, which I didn't, it was bought this way.

Built Master Had another look.....it's the borderline between blue and brown.....old guns eventually go brown, especially if used a lot,like an old double...... The bluing done on British military guns is very durable, and looks like it has thickness like paint..... This kind of bluing cannot be done without using “corrosive sublimate”, a very poisonous chloride of mercury.(all salts of mercury are very poisonous)....so outside a third world country,the bluing cant be duplicated. Built Master Bluing is just a controlled rust.
