LEVELING AGENT
Hello, I’m just starting out with electroplating. After about three hours, nodules consistently form on my ring. I’ve done some research and understand that using a leveling agent would be better, but I’m not sure which one to choose. I live in France. My solution consists of copper sulfate, 15% battery acid, and demineralized water (used for copper-plating jewelry), and I’m also using a magnetic stirrer. Thanks in advance.
