In this second part of my polishing series, I’m focusing on how to use tumblers to polish copper electroformed jewelry. Tumblers are incredibly helpful when it comes to smoothing surfaces, improving conductivity before electroforming, or brightening up a piece after applying a patina. I’ve tested three types: a vibrating tumbler, a rotary tumbler, and a magnetic tumbler (the last one generously provided by VEVOR). Whether you're dealing with a dull surface, leftover oxidation, or intricate details that are hard to polish by hand, these machines can make a big difference. In this blog post, I’ll walk you through my setup and process for each tumbler, share my experiments with DIY burnishing compounds, and give you tips to get the most out of each tool. 🧰 Supplies Used Vibratory tumbler https://amzn.to/44CAFDI | https://bit.ly/3I1bMsz Rotary tumbler  https://amzn.to/4l8SqAw | https://bit.ly/4eqIWxP VEVOR magnetic tumbler  https://amzn.to/4kcQk1i | https://bit...
