Review: More black than brown & very easy to use. - I've done some patination with other chemicals and they all required heat and a spray bottle. This stuff works cold and does a nice job, but it is more on the black side than brown, but that's what I wanted for this project. Also used it on some zinc plated wood screws and it worked great. Easy to use.
Review: You must IMMERSE the item to darken - I'm giving this 3 stars because it's not nearly as quick and effective as Birchwood Casey Brass Black which can be easily applied with a Qtip. This stuff requires immersion in the liquid for it to work, which is probably fine for many things, but for my small jewelry projects a Qtip application is preferred. Birchwood Casey Brass Black is the same price but you only get 3 oz vs 16 oz of Jax. Bottom line: you have to immerse the object in Jax, and I don't know yet how long the solution lasts before (or if) it loses its blackening power in the container I'm using. Had I known this before buying I would not have purchased it, and there's a NO RETURN on this so it was a $30 mistake on my part, but I'll make it work. It's probably fine for other people. It works, just not what I was expecting.

## Features

- FAST ACTING: JAX Brown-Black works quickly, just clean the metal from lacquer, oil, grease and wax
- EASY TO USE: JAX Brown-Black is easy to apply and safe on the metal surface. Use a bristle brush, sponge or rag and apply the JAX solution directly to the metal. You may also dip the entire object into the solution. Always use JAX Products in plastic or glass containers
- EASY TO CONTROL: JAX Brown-Black has a water-based solution for antiquing or darkening metal. To dip your metal into JAX solution, you may dilute it with water to slow the reaction down and have more control over the finish
- NEVER EXPIRE: JAX products never expire; however, they can deteriorate over time if not cared for properly. Safety is the first priority. Always store JAX products at room temperature, in tightly closed original containers
- PROUDLY MADE IN THE USA BY JAX CHEMICAL COMPANY, a quarter of a century of giving our customers uncompromising quality. Go ahead, experience a metal polish that's tried and trusted

### ⭐⭐⭐⭐ Worked OK.
*by T***M on October 16, 2025*

Although it did darken it some, I needed to use something else to make it look even richer. The smell was strong.
