Quest for Black Pots!



 

Hello,

Anybody know how to take a bright brass finish (Like the type you would find on a polished pot from Pier 1) and turn it an even dark black?

The simplest solution is to dissolve copper carbonate this on eBay or Amazon [affil links] (powder form) in ammonia this on eBay or Amazon [affil links] until this saturates. You will obtain a navy blue solution that must be kept refrigerated. The parts, perfectly cleaned are dipped in the solution. Depending on the copper content in the brass alloy you will get different shades from dark brown to black.
