🔬 How to Test (Step-by-Step)

Streak Test (Recommended): Firmly rub your test piece across an assay touchstone to leave a clear, visible gold streak.
Apply One Drop: Squeeze a single drop of 14ct–24ct solution directly onto the streak mark using the precision nozzle.
Observe the Reaction:
- Genuine 14ct–24ct gold holds its bright colour and remains untouched.
- 9ct gold, rolled gold, or plated base metals rapidly fizz, discolour, or dissolve away.
Clean: Neutralise with water or neutraliser solution, then wipe clean with a tissue or cloth.
