Platinum First Cut .92 lb Bar-Japanese Polishing Compounds

This Japanese-made "First Cut" compound is an industry-leading abrasive for the initial stage of platinum finishing. It features a unique blend of minerals that can quickly remove 100 percent of the "skin" or oxidation found on raw platinum castings. Despite its aggressive cutting power, it leaves a uniform surface finish that is easy to refine in subsequent polishing steps. This 0.92 lb bar is an essential part of the toolkit for any high-end jeweler working with difficult-to-finish noble metals.
