In the final production phase, silver castings undergo a cleaning process to achieve the desired shape and smoothness. This process removes the sprue system. The commercial appearance, aesthetics, and precision of the casting surface finish are crucial for assessing the quality of the jewelry. Key stages of post-casting processing include removing the sprue system by cutting it off, followed by cleaning the area on a specialized cleaner. Giving the castings their final appearance requires manual work, demanding significant practical experience and dexterity.
