Choosing the antique versus polished brass finish can be a challenging. Out rule of thumb is that if you are looking for the hardware to enhance your piece in a subtle way, choose the finish that is closest to the color of your piece. If you are looking for the hardware to pop, the choose the finish that is not like the color of your furniture. So, if your dinning room furniture is dark and you want the hardware to stand out, choose the polished brass finish. If you are looking for a more subtle effect, choose the antique finish. In our antiquing process, each item is treated with a chemical process that 'ages' the brass giving the pieces the rich patina seen on antiques. Each piece is done by hand and all of the items from your order are done at the same time to ensure that all of your pieces have the same finish. Antiquing may delay shipping by two to three days. Please note that the actual color of the antiqued item may differ slightly from the above picture due to variations with computer monitors. Mounting hardware is included. It's just like grandmas! It's something we hear from people restoring or refinishing a dining room set or bedroom suit from the 1930's and 1940's.
