The ultimate Japanese finishing compound for notoriously difficult hard metals. Polishing dense, high-friction metals like platinum and titanium requires a specialized abrasive matrix. Standard rouges tend to drag, smear, or overheat the surface. Manufactured in Osaka, Japan, the Biso Orange Luster Compound (BS-New Poliart No. 7000) is engineered specifically to overcome these metallurgical challenges. It delivers a flawless, ultra-high mirror luster on hard alloys while serving as a highly versatile "all-rounder" for gold and standard precious metals.
Advantages
-
Hard Metal Mastery: The abrasive structure is chemically and physically optimized to cut and finish Platinum, Palladium, Titanium, Zirconium, and Stainless Steel without surface dragging.
-
Easy Wash-Off Formula: A massive time-saver at the bench. Hard metal polishes are traditionally extremely greasy and difficult to clean out of diamond settings. Biso’s proprietary binder is formulated to wash easily off hands, jewelry, and intricate settings, drastically reducing your ultrasonic cleaning time.
-
Highly Concentrated Yield: This is a premium, high-density compound. You only need to apply a very light skim to your buffing wheel. Over-charging the mop will actually reduce the cutting efficiency—a little goes a remarkably long way.
-
The "Mixed-Metal" All-Rounder: While it shines on platinum, it is incredibly effective on Karat Gold. This makes it the perfect compound for polishing two-tone jewelry (e.g., 18k Yellow Gold bands with Platinum prongs) without needing to switch wheels or compounds mid-polish.
Bench Tip: Less is More
For the absolute best mirror finish, apply this compound sparingly to a clean, unstitched fine cotton or flannel mop. Let the high-quality Japanese abrasives do the work; applying too much pressure or too much compound will result in a hazy finish.
