How to Use for Gold Testing?
Step 1:
Rub the gold colored item on the gold testing stone until it leave a visible mark.
Step 2:
Apply Acid 1 on the mark & the acid will dissolves the mark of any item which is not gold.
Step 3:
If the mark remain while testing Step 2, you may continue to Test on Acid 1 & Acid 2(Mix) for fineness testing.
Testing for gold with acid capitalizes on gold's status as a noble metal, resistant to corrosion, oxidation, or acid. The procedure includes rubbing the gold-colored item on black stone, leaving a visible mark. The mark undergoes scrutiny by applying (Acid 1), which dissolves the mark of any item not gold, stainless steel, zinc, tungsten, aluminum, platinum, or palladium. If the mark persists, further testing involves (Mix of Acid 1 & Acid 2). If the mark dissolves, the item proves to be genuine gold. More precise assessment of fineness or purity is achieved using varying strengths of (Mix of Acid 1 & Acid 2) and comparative testing against known fineness.
