The Inquartation method is one of the most common methods of refining low and medium karat gold jewelry (9K-18K) and can also serve the first step in refining sterling silver. Inquarting usually doesn't apply to high karat gold jewelry (21K-24K) since it is low in silver content. A low silver content (less then 8%) will not create passivation of the metal and therefore can be dissolved ...
