Bronze disease is an irreversible and nearly inexorable corrosion process that occurs when chlorides come into contact with bronze or other copper-bearing alloys. [1] It can occur as both a dark green coating, or as a much lighter whitish fuzzy or furry green coating. [1]
The actual attack on the metal is by the corrosive action of the water to which it is exposed while the erosive factor is the mechanical removal of the corrosion product from the surface. Impingement attack produces highly characteristic water-swept pits, which are often horseshoe shaped, or it can produce broader areas of attack.
Tarnish does not always result from the sole effects of oxygen in the air. For example, silver needs hydrogen sulfide to tarnish, although it may tarnish with oxygen over time. It often appears as a dull, gray or black film or coating over metal. Tarnish is a surface phenomenon that is self-limiting, unlike rust. Only the top few layers of the ...
Sealed, or lacquered, copper will present as much shinier than raw, or natural, copper—and it's also much easier to clean (tackle sealed copper with a warm, wet dishcloth and dish soap).
The mechanism for copper begins the same as for steel, evolution of the inhibitor. Once at the copper surface however, the inhibitor will form a copper benzotriazole complex which is protective. [9] Vapor pressure is a critical parameter in VCI effectiveness. The most favorable range of pressure is 10 −3 to 10 −2 Pa at room temperature ...
A wine dispenser. Wine dispensers are devices designed to serve and preserve wines. Dispensers store stored wines at cool temperatures and oxygen is prevented from entering the bottle when pouring. Wine dispensers vary greatly in use and function, most commonly wine dispensers are used in restaurants and bars to prevent spoilage when selling ...
Spray away grease, ink, blood, red wine, coffee, makeup, food, grime, dirt and even set-in stains. "I bought this to take to work to help get stains off carpets," according to a five-star reviewer.
The safest and most easily available cleaning option for most wine glass owners is to “wash by hand with very hot water and mild soap,” says Darrin Ylisto, co-owner of natural wine shop Really ...
