Brassager: Premium Brass Ager Darkening Solutions for Brass, Copper & Bronze

Brassager makes a premium metal darkening solution that gives brass, copper, and bronze an authentic antique patina without damaging the metal. Our flagship Brass Ager formula is made in the USA by a family-owned business with over 14 years of experience, and it delivers old-world character in minutes, not decades.

Built by Restorers, for Restorers

Our formula began in our own vintage hardware restoration business, where we needed a reliable way to age new and bare metal to match original pieces. We developed it in-house, and when customers kept asking to buy it, Brassager was born. Every bottle reflects years of real-world restoration experience.

Why Choose Our Darkening Solution?

• Total color control: The gradual color change lets you stop at exactly the shade you want, from warm golden-brown to deep, dark antique.
• Zero dimensional change: Darkens the surface without pitting, thinning, or altering the shape of your metal.
• Easy to apply: No special equipment or complicated prep.
• Versatile: Works on brass, copper, and bronze.
• Made in the USA: Trusted by hobbyists, restorers, and professionals.

Perfect for Hardware, Lighting, Décor & Restoration Projects

Use it to match aged finishes on cabinet hardware, hinges, drawer pulls, lamps, light fixtures, furniture hardware, and decorative metalwork. Whether you’re restoring a single antique piece or outfitting a full project, Brassager gives new metal a believable, time-worn look.
