Today, many homeowners strive to achieve a lived-in vibe with their interior design choices. Who wants furniture that looks like it just came out of a catalog? Or a pallet project that trumpets the fact that it was made just last weekend? Those same DIYers who go to great lengths to distress wood so their furnishings radiate vintage appeal also don’t want brand-new metal accents that stick out like a sore thumb. The solution? Age the metal to conceal the recent genesis of your furniture while creating a striking decorative finish. Unlike such materials as glass or tile, metal may even look better with a little antique patina than it does in its unblemished state—so much so that you might want to age all your metal accents. Fortunately for DIYers, the prospect of aging metal yourself doesn’t have to give you gray hairs. Read on to learn how to take the shine away from silver, copper, and cast iron with a minimum of steps and materials.

 

How to Age Metal - Tarnished Silver

Method #1: When Sulfur Met Silver

MATERIALS AND TOOLS
- Dish soap
- Plastic gloves
- Large pot
- Water
- Eggs (one or two)
- Plastic freezer bag
- Paper towel (optional)
- Soft cloth

NOTE: This technique works best on sterling silver of 92.5% purity or lower.

STEP 1
Before aging silver, hand-wash it with soap and cold water to remove surface oils. Put on a clean pair of gloves before handling the washed silver to prevent the oil on your fingers from transferring to the piece.

STEP 2
Bring a pot of water to a boil, toss in one egg (or two, for larger silver pieces), and cook until the egg is hard boiled. Remove the egg from the pot and crack it open, separating the yolk from the white.

STEP 3
Place the silver into a freezer bag with the crumbled yolk of the hard-boiled egg, but don’t let the yolk touch the silver. (If they touch, you may end up with spotting in your new patina.) For larger pieces of silver, you may need to use a paper towel to separate the metal from the yolk. Seal the bag, and let it sit for six to eight hours. The silver will soon begin the aging process, thanks to the sulfur in the eggs.

STEP 4
It’s time to unleash the power of science! Open the bag outdoors so the sulfur fumes don’t invade your home. Remove and clean the aged silver with soap and water, gently buffing the high points with a clean cloth to reveal a rich patina.

Method #2: Photo-Finish Copper

MATERIALS AND TOOLS
- Soap
- Water
- Steel wool
- Shallow plastic tray
- Rapid fixer (found in camera stores)
- Vinegar (optional)
- Salt (optional)
- Gloves
- Soft-bristle brush
- Copper sealant spray

STEP 1
Clean the copper with soap and water to remove surface residue, then scrub it with steel wool.

STEP 2
Fill a shallow plastic tray with a solution of two tablespoons water and a tablespoon rapid fixer—a fluid used for photographic processing. If you prefer copper with a blue-green complexion, swap the rapid fixer for a solution of equal parts vinegar and salt.

STEP 3
Put on gloves, and submerge the clean copper in the solution for up to 10 minutes. You can also use a brush to coat the surface of the copper.

STEP 4
Remove the copper from the bowl and let it air-dry completely to reveal either a dark patina or a timeworn turquoise tint, depending on the ingredients you selected in Step 2.

STEP 5
Rinse the copper in cool water. Allow the piece to dry fully before coating it with a fast-drying copper sealant spray, which will maintain its beauty for years to come.

Method #3: Make an Impression on Cast Iron

MATERIALS AND TOOLS
- Hammer
- Sandpaper (optional)
- Dust mask (optional)
- Soft cloth
- Paintbrush
- Antiquing solution
- Cast iron paint
- Clear varnish

STEP 1
Lay any decorative piece of cast iron flat on a sturdy surface. Using the claw end of a hammer, ding random locations on the cast iron until you have achieved a rugged, uneven pattern. If you prefer a less rough-hewn patina, run a piece of fine-grit sandpaper across the cast iron to create more subtle blemishes. Don’t forget to wear a dust mask when using sandpaper so you don’t inhale any fine metal shavings.

STEP 2
Wipe off any metal dust from the cast iron with a soft cloth.

STEP 3
To complete the look of a realistically rustic cast-iron surface, apply store-bought antiquing finish or a few coats of cast iron–friendly paint, followed by clear varnish.
