What is Raw Copper Chain?
Raw copper chain is solid, "bare" copper that has not been treated with anti-tarnish coatings, lacquers, or plating. Unlike "copper-colored" chains (which are often brass or steel with a thin surface coating), raw copper is consistent throughout.
Because the metal is left in its natural state, it is highly reactive to oxygen and moisture. This leads to the development of a natural patina, a process that causes the metal to transition from a bright, "new penny" orange to a deep, vintage bronze or even a turquoise verdigris over time.
Why Artisans Choose Raw Copper:
- Custom Patina: You can "force" an antique look using Liver of Sulfur or ammonia.
- Soldering: Because it is unplated, it is the best choice for jewelry makers who need to solder links.
- Holistic Benefits: Many wearers prefer raw copper for its perceived anti-inflammatory properties and help with joint pain.
- Sustainability: Solid copper is 100% recyclable and lacks the harsh chemicals used in some plating processes.
How to Care for Raw Copper Jewelry
The beauty of raw copper is its versatility. You can either embrace the darkened, rustic look of oxidation or keep it polished to a high shine.
1. Cleaning and Restoring Shine
If your copper chain has become too dark, you can easily restore its original luster using common household items:
- The Lemon & Salt Method: Mix lemon juice with a pinch of salt. Soak the chain for 1–2 minutes, scrub gently with a soft toothbrush, rinse with water, and dry immediately.
- Commercial Cleaners: Use a specialized copper polish or a jewelry polishing cloth (like a Sunshine Cloth) for a mirror-like finish.
2. Preventing Tarnish
To slow down the oxidation process and keep your copper bright for longer:
- Keep it Dry: Always remove copper jewelry before swimming, showering, or exercising.
- Store Properly: Store your chains in an airtight Ziploc bag with an anti-tarnish strip.
- Avoid Chemicals: Keep the chain away from perfumes, lotions, and hairsprays, which accelerate darkening.
3. Dealing with "The Green Skin" Effect
Raw copper reacts with the acidity of your skin’s oils, which can sometimes leave a harmless green tint on the wrist or neck.
- The Solution: You can seal the inside of the chain or bracelet with a specialized jewelry sealer (like ProtectaClear) or even a thin coat of clear nail polish to create a barrier between the metal and your skin.
