Polished brass door furniture
Brass is the base material for many types of finishes. The most popular being POLISHED and LACQUERED brass, POLISHED CHROMIUM PLATED brass, SATIN CHROMIUM PLATED brass and ANTIQUE brass. Polished and lacquered brass will retain its shine until the lacquer wears away and then it will start to tarnish. This means that it will gradually change to firstly dull light brown then gradually darken. If exposed to water it will sometimes turn green to start with before settling to a matt brown finish. This metal can always be revived. Initially by the use of a metal polish (any finely abrasive cream or liquid will suffice) and in the case of more sever tarnishing an initial rubbing with wire wool. There are 8 grades of wire wool. The finest 0000 grade is similar to cotton wool and is ideal to use in the early stages of tarnishing as it will not leave visible scratches on the soft metal. Using the coarser grades will do the job quicker but is more likely to leave scratches on the surface that is being polished. Many people love to polish their brass regularly has it gives them a sense of satisfaction to perceive the highly polished finish that they have achieved. Once a polished finish is attained it is possible to apply a coat of clear lacquer that will maintain its polished appearance until the lacquer wears away. Lacquered surfaces are not suitable nor do they need polishing.
Another way to maintain a bright polished finish is to use Physical vapor deposition (PVD) brass.This is a variety of vacuum deposition* that is used to deposit a thin film* by the condensation of a vaporized form of the desired film material onto the metal surface. This then protects the surface of the door furniture and gives it a 25 year anti tarnish guarantee.
*Vacuum deposition is a family of processes used to deposit layers atom-by-atom or molecule-by-molecule at sub-atmospheric pressure (vacuum) on a solid surface. The layers may be as thin as one atom to millimeters thick (freestanding structures). There may be multiple layers of different materials. A thickness of less than one micrometer is generally called a thin film* while a thickness greater than one micrometre is called a coating.
