Blackened Copper Patina works on bronze, brass and copper. This is a concentrated patina and requires dilution before use (typically 10-50% with distilled water). Depending on the dilution amount and application method, it will produce a beautiful transparent black finish.
Blackened Copper Bath Patina reacts just like the regular Traditional Blackened Copper Patina, but is made for an immersion process. It is also concentrated and should be diluted before use.
