- Place drops of the different gold test solutions on the line (9ct, 14ct, 18ct, 20ct).
- Wait for one minute.
- Where the scratch line is still visible, that indicates the carat value.
- If the item was made of brass for eg, the scratch line would disappear.
How To Test For Platinum
- Make a scratch line with the platinum piece to be tested on the test stone.
- Place a drop of the platinum test solution on the line.
- Wait for one minute.
- If the scratch line remains visible, that is a positive test for platinum.
- For other metals, the scratch line will disappear, indicating it is not platinum.
How To Test for Silver
- Remove all impurities from the surface of the silver piece to be tested by using a solvent like thinners, etc.
- Place a drop of the silver testing solution on the item to be tested. Always test on a inconspicuous section of the piece
- If it is silver, the drop will become red. The degree of redness depends on the quality of the silver.
- On sterling silver (925 silver) the drop will become light red.
- On silver plate the solution will become darker red.
- Other metals will not show up as red.
