What it is and what it does. Antique bronze solution QLQ-20A is component A of the two-part QLQ-20 antique bronze system, the metal-bearing part that produces the bronze colour on copper-tin deposits.
- Blue-green clear liquid, used with component B of the same system.
- The colour is produced by a controlled reaction with the bronze deposit rather than by electroplating a separate layer.
- Frequently used after barrel bronze plating to give the aged, value-added look on sliders and hardware.
