The Gold Testing Acid Solution Kit provides a reliable method for determining the karat value of gold items.
It includes test acids for 10kt, 14kt, 18kt, and 22kt gold, which can be used alongside test needles and stones to assess purity.
The testing process involves scratching the metal onto the stone, applying a small amount of acid, and observing the rate at which the metal dissolves.
This approach allows for differentiation between different gold karat levels, helping users verify gold quality with consistency.
The kit offers a practical, budget-friendly solution for those requiring accurate gold testing without specialized equipment.

14K Gold Karat/Value Testing Solution Gold test acids, when used with test needles and test stones, determine the gold karat value of articles being tested.
10kt, 14kt, 18kt and 22k test acids are available. Scratch or rub the metal onto the testing stone. Place a half a drop of the closest acid to the karat you estimate the metal to be.
If the acid dissolves the metal it is less then the karat level of the acid use and you should try again with lower level acid.
If the metal dissolves the slowly, the metal is slightly less than the karat level of the acid in the bottle. If the metal does not dissolve it is the karat level of the acid in the bottle or higher.
Use a test needle to scratch and compare the speed the metal dissolves to more closely determine the gold purity level.
