Traditional and classical, brass plaques are a favourite for a prestigious opening or memorial and professionals business plaques. The gold finish fits well with a rustic or historic location and where a distinguished and elegant look is sought.
Signmakers supply brass plaques in two finish options - polished (mirror) or linished (brushed) both of which are usually finished in a clear protective lacquer.
Polished/mirror finish is highly reflective and text can be difficult to read. Polishing adds to production and handling costs. It is still a very popular and traditional finish but better suited to smaller plaques and nameplates.
Linishing reduces the reflectivity of the metal and text is clearly legible. Retaining the warmth of brass the linish gives more flexibility for using brass and a more contemporary look.
While the brass itself will last indefinitely in most situations it is not possible to permanently protect the finishes and the metal will tarnish (go a darker brown colour) over time, regardless of clear lacquer protection. Time taken for this to happen depends on the environmental conditions.
Some prefer to keep the brass in its natural state, without protective clear lacquer and let it age to tarnish naturally and uniformly or to keep it sparking with regular attention with a cloth and some Brasso. As with any engraved metal the engraved lettering if left natural will still be legible against the surface material. If you are wanting to achieve an aged look quickly a bare metal plaque may be the way to go.
