Oil-Rubbed Bronze - Danish Style

Allegion’s aged bronze finish (643e) resists the color change and fading that occurs naturally with the oil-rubbed bronze finish (613).

A couple of weeks ago, one of my Allegion coworkers pointed out a problem with the images on a post from 2009.  The post was announcing a *new* finish called aged bronze (643e), which was created as an alternative to US10B – oil-rubbed bronze (613).  Since people continue to access the 2009 post, I think I can safely assume that hardware consultants are still being asked to specify the US10B finish, and using the photos in the post to show what can be expected over time.

Allegion’s Knowledge Center includes this information about the US10B – oil-rubbed bronze finish:

The BHMA 613 (US10B) finish is not intended to be color-fast and has been specified for many years by architects who wish to have an antique look with their hardware. To make this finish, the brass or bronze base material is dyed and oxidized to a brown color, and then satin polished and oil rubbed. The oil slows the acceleration of the antique look until it reaches the job site. Once the product is installed to the door, the oil should be wiped off so the antique effect can begin quickly. After a period of a few weeks, the brown oxidation will wear off, due to handling, which will expose the base material underneath and achieve the desired results.

Depending on the desired look, either aged bronze or oil-rubbed bronze may be the right finish for a particular project, but it’s important to know what to expect.  With the US10B finish, the hardware will change color over time, especially wherever it is touched or cleaned.  As I walk the streets of Copenhagen, I am seeing A LOT of examples of bronze hardware that demonstrate the effects of the oil-rubbed bronze finish:
