🔧 What it does & how to use
This is burnishing media for a jewellery or metal tumbler, used to work-harden and polish precious metal items — rings, chains, findings and small components — to a bright, smooth finish without removing material. It's suited to both hobbyist and professional jewellery makers.
-
Load: Place your metal pieces into the tumbler barrel along with the 2mm steel balls, filling roughly two-thirds full with media.
-
Add liquid: Add water and a burnishing compound or a drop of mild soap to help lubricate and clean as it tumbles.
-
Run the tumbler: Run the barrel for the time recommended by your tumbler's instructions (typically 1-3 hours), checking progress periodically.
-
Rinse and dry: Remove the pieces, rinse off residue, and dry thoroughly — you should be left with a bright, burnished surface.
-
Store the media: Drain and dry the steel balls after use to keep them rust-free for next time.
A separate listing is available for 3mm round balls if you need a coarser media size.
