Japanese Polishing Compounds: Premium Polishing Performace!

For a superior surface finish every time!

When polishing challenging surfaces such as platinum, palladium, stainless Steel, white gold, silver or yellow gold, our go-to recommendation is our Japanese polishing compounds.

The Japanese Polishing Compound Difference

High-end jewelers choose Japanese polishing compounds over traditional polishing compounds because of its performance. The immediate differences are the purity of the material and control they offer during the polishing process.

Each compound has a specific grit number that determines the cutting ability of the material, ranging from #800 (heavy cut) to #8000 (Finest). The proper method for polishing metal surfaces is in steps, from cutting aggressively as needed to a final high polish.

The silicon carbide grain size impregnated in each Japanese polishing compound is specific to the compound grit's number rating. Lower cost polishing compounds have a wider range of abrasive grains and are designed for general polishing. Japanese polishing compounds allow better control during the polishing process, release quickly from metal surfaces during washout resulting in less time in an ultra-sonic, and are specifically designed for jewelry polishing applications.

Romanoff's Recommendations

We always recommend a 3-step minimum buffing process using differently marked buffs for each grit compound. Our own Romanoff Blue Buffs are perfectly suited for this application.

For small parts or earrings you can use a 4” x 50 ply blue buff, a 6” x 50 ply blue buff for rings or heavier pieces or 6” razor Edge buff for polishing in between prongs and grooves.

Recommended Buffing Order

Use Buff #1 for your first cut. Use either Platinum First Cut (#800 grit) or Platinum Lapping Compound .92lb Bar (#1500 grit) polishing compound. These compounds are ideal for raw castings or heavily marked surfaces. When split lapping or blind lapping, use Platinum Lapping Compound .92lb Bar (#1500 grit) or Romanoff Platinum Greystar polishing compounds.

Use Buff #2 for medium cutting in tandem with our Fine Cut (#4000 grit) or Extra Fine (#6000 grit) compounds. These are popular for remounts, repairs or preparation before final polish. You may consider washing out the parts in an ultra-sonic before the final polishing step.

Use buff #3 for the final polish, using our Super Shine (#8000 grit) or Wasabi (#8000 grit) final polish compounds for a mirror finish.
