Vinegar Patina Etching on Bronze

Using acidic solutions (vinegar, salt, ammonia fumes) to create controlled verdigris and patina patterns on bronze and copper work. Combines the oxide layer chemistry from mordant-dyed tempering with the bronze work from singing bowl hammering, creating decorative and protective finishes through deliberate corrosion rather than heat treatment.

Vinegar Patina Etching on Bronze

I sealed a cracked singing bowl in a container with ammonia-soaked paper towels. This is either chemistry or a cry for help.
