JSP® Blak-Ox Patina Solution – Deep Black Oxidizing Finish for Gold, Silver, Copper, Brass & Bronze (3 oz)

JSP® Blak-Ox produces the darkest, smoothest, deep-black patina available for silver, gold, copper, brass, and bronze. Formulated for jewelers and metal artists, this professional-grade oxidizing solution delivers a bold antique finish that enhances engraving depth and contrast.

The liquid mixture contains 3 oz of hydrochloric acid blended with proprietary darkening agents to ensure fast, even coloration. Simply apply directly for a rich black finish or dilute with water to create subtle shades of gray. Perfect for jewelry, sculptures, and decorative metalwork where a deep oxidized appearance is desired.

To prevent unwanted oxidation of nearby metals, always seal the bottle tightly, double-bag after use, and store away from metal surfaces. Handle with care and use in a well-ventilated area.
