Use with black test stone, draw two lines alongside each other using test gold and reference gold (known carat value) Apply acid over both then observe the unknown carat strip disappear (meaning lesser carat value than reference gold) or if the test gold strip remains (carat value is equal to or greater than reference gold) if the line remains use the next gold test acid with a higher value until the line of reference gold disappears to reveal the carat value of the test gold.
