Actual rust bluing is not a cold process. The solution is applied cold to bare metal, then the part is immersed in boiling water for about 15 minutes until a black 'crust' forms. Then the crust is carded off on a fine wire wheel leaving the rust-blue finish. Takes several applications. If you are referring to the cold-blue kits sold commercially, I dont believe you will like the results. In order to get ANY kind of decent color, the metal must be absolutely clean and oil-free. The best types we've found to use are Oxpho-Blue and Blue Wonder. They give the darkest finish without too much of the rotten-egg smell. repair@countrygunsmith.net
The chemical used for cold bluing is usually Selenium_dioxide.
If cold they hibernate. if hot they go in the water
the cold temperture may harm plants and kill the cells that helps the plants to grow.
The skin responds to heat, water, pain, cold and anything that you can feel
The most common engineering material I have worked with that forms a passive oxide film is Aluminum which forms the film when contacted with air. Some types of Stainless Steel can also be induced to form a passive oxide film by treatment with nitric acid. "Hot bluing" can be used to provide limited protection to other types of iron and steel by bathing them in hot aqueous solutions of potassium nitrate or sodium hydroxide to form a layer of magnetite (Fe3O4). Note that regular red rust is Fe2O3. "Rust bluing", "cold bluing" and carefully controlled heat treatment of iron and steel pieces can also be used to impart a protective oxide finish. All of these bluing processes still require additional treatment with oil to provide lasting protection.

Most gun shops, sporting goods stores, on line. Please note that cold bluing products generally do not work as well as hot, professional bluing.
Bananas respond fairly poorly to the cold. They tend to shrivel and become smaller.

Most bears respond to the cold by hibernating through the winter months. Polar bears are an exception because they just keep hunting no matter how cold it gets.
