Brass is a versatile metal alloy composed primarily of copper and zinc. It has a distinctive golden yellow color and is valued for its malleability, corrosion resistance, and acoustic properties. While solid brass stock can be purchased, it is also possible to give other metals a brass finish through a simple chemical reaction process.

Transforming metal into brass can provide an inexpensive way to restore vintage hardware, lamps, decorative items, and more.

Creating a Brass Finish

The most common method for turning other metals into brass involves the use of liver of sulfur. This chemical solution reacts with the surface of many metals to create a brass-like appearance. The process causes the metals to undergo a color change through an oxidization reaction.

With proper handling, liver of sulfur can safely turn small metal objects a golden brass tone. However, it does have a strong rotten egg odor during use. It also requires careful prep work and safety precautions.

An alternative product for brass finishing is called brass black. This chemical solution works similarly but creates a blackened brass effect. It may be preferred for a more antique or distressed look.

For small brass finishing projects, beginners may opt for an even simpler approach. Wax-based brass finishing products like Rub ‘n Buff allow brass transformations without chemicals. They can create convincing brass tones on metal, wood, glass, and more.

Benefits of Turning Metal into Brass

Some key advantages of turning other metals into brass include:

Cost savings – Brass finishing can restore vintage items at a fraction of the cost of remaking them in solid brass.
Customization – You can choose which metal antiques, furniture pieces, decor items, etc. to transform into brass.
Ease of use – Brass finishing products are readily available and easy to apply.
Durability – The brass tone becomes a permanent finish on the metal surface.
Low maintenance – Brass finishes do not require continued polishing or lacquering like solid brass.
Safety – Products like Rub ‘n Buff allow brass finishing without harsh chemicals.

Supplies Needed

To turn metal into brass, you will need:

Brass finishing product – Such as liver of sulfur, brass black, or Rub ‘n Buff.
Metal objects – Such as antique hardware, lamps, vases, candle holders, or other decor items. Avoid zinc, cast iron, and natural brass.
Prep supplies – Sandpaper, steel wool, masking tape, cotton swabs, cleaning agents, plastic containers, and disposable gloves.
Application tools – Soft cloths, paintbrushes, cotton swabs, sponges, or foam brushes.
Finishing supplies – Steel wool, metal polishing cream, clear coat spray, microfiber cloths, and wax paper.

Safety Precautions

When using brass finishing chemicals, proper handling is imperative:

Work outdoors or in a well-ventilated area.
Wear gloves and eye protection. Avoid skin contact.
Follow all label instructions carefully.
Store solutions securely in sealed containers.

For added safety, opt for a wax-based brass finish product instead of chemicals. Rub ‘n Buff and similar products minimize risks.

How to Turn Metal into Brass with Liver of Sulfur

If using liver of sulfur solution, follow these steps:

Step 1: Prepare the Metal Surface

Clean the metal thoroughly with soapy water to remove any oils, dirt, or existing finish.
Lightly sand the surface with fine grit sandpaper.
Wipe clean again with denatured alcohol using cotton swabs or a soft cloth.

Step 2: Apply Masking Tape

Cover any areas you do not want to change color with masking tape.
Use extra tape around joints, seams, or detailed edges.

Step 3: Mix the Liver of Sulfur Solution

Don protective gloves, eye wear, and work outdoors or in a ventilated area.
Mix a liver of sulfur concentrate with hot water per product instructions.
Pour into a plastic container large enough for dipping.

Step 4: Dip and Remove Metal Object

With tongs, dip and submerge the item in the solution for 30 seconds to 5 minutes.
Remove and rinse thoroughly in clean water to stop the reaction.
Repeat dipping if a darker finish is desired.

Step 5: Remove Tape and Dry

Use steel wool to gently remove any dark spots on raised surfaces.
Remove all masking tape once satisfied with the finish.
Allow the item to dry fully before applying any top coat.

Step 6: Apply Protective Coating (Optional)

For added durability and sheen, apply a spray-on clear coat gloss finish.
Alternatively, rub on a thin coat of Renaissance Wax to protect the patina.

How to Turn Metal into Brass with Brass Black

The process for using brass black solution is very similar:

Step 1: Clean and Prepare Surface

Follow the same cleaning and light sanding techniques. Tape off any areas as needed.

Step 2: Apply Brass Black

Use a paintbrush to coat the item with brass black solution. Let it sit for 2-3 minutes.

Step 3: Rinse and Rub Down

Rinse thoroughly with clean water and dry immediately with a soft cloth. Rub gently with steel wool to smooth and antique the finish.

Step 4: Remove Tape and Apply Protective Coating

Once satisfied with the level of blackening, remove the tape. Apply a top coat if desired for added protection.

How to Turn Metal into Brass with Rub ‘N Buff

For a simple brass finishing technique, Rub ‘N Buff is ideal for beginners.

Step 1: Clean and Prepare the Surface

Lightly clean and sand the metal item first. Tape off any areas as needed.

Step 2: Apply Rub ‘N Buff

Use a soft cloth or foam brush to apply a thin layer of Rub ‘N Buff wax evenly over the surface.

Step 3: Buff the Finish

Immediately buff with a clean cloth to create a smooth, shiny brass effect. Add a second coat if needed.

Step 4: Remove Tape and Seal (Optional)

Carefully remove any masking tape. Seal with a clear coat spray for added protection if desired.

Benefits of Using Rub ‘n Buff Instead of Brass Paint

There are several advantages to using Rub ‘n Buff over traditional brass spray paint or acrylics when giving metal a brass makeover:

Super easy to apply. Just use your fingers or a soft cloth to apply a thin layer of Rub ‘n Buff directly onto metal. No need for multiple paint coats, primers, or sealers.
Dries quickly. You can buff off any excess Rub ‘n Buff right away and the finish dries within minutes. No waiting hours or days for paint to dry!
Doesn’t chip or scratch off. Rub ‘n Buff maintains a flexible finish that won’t crack or peel like paint. It’s durable for indoor use.
Adds texture and dimension. The Rub ‘n Buff finish brings out the natural grain, hammer marks, and imperfections of metal rather than covering them up. This gives metal a rich, dimensional look.
Achieves a realistic aged brass patina. Unlike shiny brass spray paint, Rub ‘n Buff has a muted, natural-looking patina like real aged brass.
Allows for selective application. You can use painter’s tape to mask off certain areas and apply Rub ‘n Buff just where you want it.
Cost effective. One small pot goes a long way and costs a fraction of the price of spray paint while achieving better, longer-lasting results.

Tips for Achieving the Best Brass Finish

Go slowly and apply brass finishing products sparingly for ideal results.
Repeat the process multiple times for a deeper, richer brass tone.
Mix liver of sulfur solutions in glass, plastic, or ceramic containers, not metal.
Use soft cloths or cotton swabs to gently rub and antique the finish.
Brass finishing won’t work well on zinc, cast iron, or natural brass metals.
If you make mistakes, quickly rinse the item under water to stop the reaction.
Properly label and store any leftover brass finishing chemicals.

Caring for Brass Finishes

Once your metal objects have been transformed, a brass patina should remain stable with proper care:

Gently dust items with a soft cloth to keep finishes looking their best.
Avoid using harsh cleaners, chemicals, or abrasives on brass finishes.
For added protection, apply a thin coat of Renaissance Wax periodically.
If finishes become dull, gently buff with a microfiber cloth or apply another thin layer of Rub ‘N Buff.
Spot clean fingerprints or oil smudges as needed with a mild cleaner.

With the right products and techniques, it is simple to turn metal into brass. Experiment with small decorative items first to perfect your method before moving on to larger brass finishing projects. And be sure to take necessary safety precautions when using chemicals like liver of sulfur. In no time, you can affordably restore beloved antiques and fixtures with stunning brass tones.
