Sealing and Protecting Your Work

One of the most common sealers used in the jewelry industry is Renaissance Wax.

Ren Wax is a microcrystalline wax polish that leaves a clear, residue-free coating.

It's petroleum-based and has a strong odor, so you'll need to wear a mask and gloves when applying it.

To use Ren Wax, clean the metal first, then rub on a thin layer.

Allow it to dry, and buff it to a glossy finish with a clean rag.

Another option is a product called ProtectaClear. It comes in both liquid and spray forms.

For the liquid version, simply dip your finished piece and let it dry.

With the spray, suspend your jewelry and apply several light coats, allowing each layer to dry before adding the next.

This sealant dries clear, is safe for nearly all metals, and provides scratch resistance.

It also dries quickly usually within an hour and is environmentally safe.

While it's a bit more expensive, it can be well worth the investment.

If you're at a craft or hardware store, you can grab a spray can of matte, clear, or glossy sealant by Krylon.

Suspend your piece and spray light, quick coats, allowing each layer to dry before applying the next.

This acrylic sealant is both UV-resistant and scratch-resistant. It's commonly used for mixed-media projects since it's safe for paper and other porous materials.

Another sealant you can find at most craft stores is Mod Podge. It now comes in spray form and offers multiple finish options.

It's great for mixed-media projects and works well on wood, paper, plastic, fabric, and metal.

Mod Podge can be sanded for a smooth finish, cleans up easily with soap and water, and is certified AP non-toxic and water-based.

One option I often use for copper and other metal pieces that get a lot of wear like rings or bracelets is clear fingernail polish.

Yes, you read that right fingernail polish!

It's easy to apply, most people already have some at home, and it provides quick, fairly durable protection for jewelry pieces like rings or even earrings.

While researching on professional jewelry sites, I came across "professional-grade" sealers such as Midas Finish Seal Lacquer.

This product is a water-based acrylic lacquer that dries clear, hard, and abrasion-resistant.

According to reviews, patience is key to achieving a smooth, lasting finish. However, like all sealants, it will eventually wear off on pieces that are frequently worn.

From all my research, there's no true long-term sealant for metal. If a piece is worn regularly, the coating will eventually wear off. Silver will tarnish, copper will oxidize, and even the most beautiful colors will fade.

Personally, I work with a lot of copper, and I choose not to seal it. I believe copper only gets prettier with time but that's just my preference.

You can also provide anti-tarnish tabs or strips for your customers to store with their jewelry. These are available from many retailers and make a great addition to packaging.

Anti-tarnish products help protect silver, nickel, copper, bronze, base metals, tin, and gold. To use, place a strip or tab near the polished metal inside an enclosed space, such as a jewelry case, storage bag, or box. They typically last about two years once activated.

Always remember: when using any of the protectants mentioned above, follow safety precautions.
Work in a well-ventilated area and wear masks and gloves.
