If you’re cutting your own shapes from metal strips or sheet, you’ll also want:

 
  Before getting started, take a moment to review some safety suggestions featured in our post titled “Safety considerations for etching metal with chemicals”.

Once you’ve reviewed the safety considerations, you’re ready to get started!

Copper, brass, and nickel silver are perfect metal choices for this process. For the best results, select metal that is 20 gauge or thicker.

How to make etched jewelry - selecting metal for your project.

First, select the metal you want to etch. You can either cut sheet metal or use prefabricated blanks. Copper, brass, and nickel silver are perfect metal choices for this process. For the best results, select metal that is 20 gauge or thicker.

 
If you’re making your own shapes from metal sheet, use metal shears to cut out your shapes. Then, flatten the cut metal with a nylon mallet and steel block.

Metal shears make cutting metal sheet a quick and easy task. The Lindstrom® shears will cut through up to 20 gauge thick soft metal sheet. Once you have cut your metal to size, use a nylon mallet and steel block to flatten it.

 
Filing the edges of hand-cut metal shapes will get rid of any sharp edges!

File the cut edges of the copper with a jeweler’s file to create a smooth finished edge.

 
Before adding the design you want to etch, make sure the surface of your metal is clean.

Clean your metal piece before etching. Begin by applying Penny Brite® Copper Cleaner to the surface of the metal.

Gently scrub with Penny Brite® Copper Cleaner and a scouring pad to remove grease and residue from the metal piece. Thoroughly rinse the piece with clean water and dry with a lint-free towel.

 
A “resist” is what you use to add your design to the metal. StazOn® ink and Sharpie® permanent markers are both great resists to use. The inked portion of the metal will be protected from the acid, resulting in a raised pattern. For more information on resists, read our “Metal Etching 101” Tutorial.

StazOn ink works great as a resist if you want to add rubber stamp patterns to your metal.

Sharpie pens work great as a resist for hand-drawn designs.

 
You can add finishing details using an extra-fine-tipped Sharpie pen. Make sure to let the ink dry thoroughly after you’ve applied your design.

Adding the final touches.

 
Make a “boat” to allow your metal blank to float in the acid tub:

How to etch metal for jewelry - make a boat to float the metal piece in the acid.

First, take a piece of styrofoam and wrap it in duct tape with the sticky side facing outwards.

 

Make a styrofoam boat to float your metal etching blanks in acid.

Wrap the duct tape entirely around the styrofoam boat, bringing the ends together.

A second short piece of duct tape can be added to hold everything together and form a tab-like handle.

 
Place your metal blank onto the face of the styrofoam float with the patterned-side out. The sticky side of the duct tape will also act as a resist, preventing acid from etching the back side of the blank.

Use a Sharpie pen handle to securely press the blank in place and seal the edges.

Ta dah! The metal blank is ready for etching.

 
Now you’re ready to place your float boat into the ferric chloride!

Use ferric chloride to etch copper and brass for jewelry.

Pour ferric chloride into a plastic container. The ferric chloride can be re-used several times, so a resealable container works best. If you are etching several items, mark the time each piece was added to the acid. Etching usually takes 20 to 30 minutes.

 
Make sure to use gloves to avoid getting acid on your skin.

Always wear gloves when handling ferric chloride during the metal etching process.

After about 20 minutes in the ferric chloride, check your metal piece. When handling the acid, wear gloves (and not just one glove like us!). Don’t risk getting acid on your skin.

 
After about 20 minutes, check to see if the etching is deep enough.

Carefully lift the metal piece out of the acid, and check the depth of the etching. If the etched pattern is too shallow, just place it back in the acid. Check again after 5 minutes.

 
Once the etching is at the depth you prefer, it’s time to neutralize the acid and clean off the design:

Neutralize and clean the acid from etched metal with baking soda.

Once the etching is completed, remove the styrofoam float from the ferric chloride and rinse it in a bath of water and baking soda. This will foam a little bit while the acid is neutralized.

Once the initial neutralizing and cleaning is complete, remove the metal piece from the styrofoam float.

And yes, it doesn’t hurt to clean the metal a bit more.

 
Polishing is the final step. If you have a tumbler, it makes your work easy! Otherwise, you can hand polish using sanding sponges and polishing pads.

A tumbler can be used To quickly polish the etched piece(s) with a tumbler, add the etched piece(s) to the tumbler barrel filled with steel shot, water, and a few drops of ShineBrite. Securely close the tumbler barrel.
