1. Why Gold-Plated Silver Bracelets Tarnish

1.1 The Science Behind Oxidation & Zkazování

  • Silver Oxidation: When silver (Ag) reacts with sulfur (H₂S) in the air, it forms silver sulfide (Ag₂S), leading to black tarnish.

  • Gold Plating Wear-Off: Over time, the thin gold layer erodes, exposing the silver underneath to oxidation.

1.2 Factors That Accelerate Tarnishing

✔ Exposure to Moisture & Humidity (pot, voda, humid climates)
✔ Contact with Chemicals (parfém, lotion, chlór, cleaning agents)
✔ Friction & Oděr (rubbing against skin, clothing, or other jewelry)
✔ Air Pollution & Sulfur Exposure (common in urban areas)

2. Výběr materiálu: Choosing the Right Base Metal & Posunutí

2.1 High-Quality Sterling Silver (925 Stříbro) as the Base

  • Proč 925 Stříbro?

    • Obsahuje 7.5% měď pro trvanlivost.

    • Less prone to rapid tarnishing compared to pure silver.

  • Nikl bez niklu & Hypoalergenní možnosti – Reduces skin irritation.

2.2 Optimal Gold Plating Thickness

  • Standard Gold Plating (0.5-1 mikron) – Wears off quickly.

  • Heavy Gold Plating (2-3 mikrony) – Lasts longer before exposing silver.

  • 18K vs. 24K Zlaté pokovování – 18K is more durable due to alloy hardness.

2.3 Alternative Base Metals for Extra Protection

  • Brass or Copper Underlay – Cheaper but requires thicker plating.

  • Rhodium Undercoating – Adds a protective barrier between silver and gold.

3. Advanced Plating Techniques to Prevent Oxidation

3.1 Multi-Layer Plating Process

  1. Nickel or Rhodium Undercoat – Prevents silver from reacting.

  2. Thick Gold Plating (2-3 mikrony) – Slows down wear.

  3. Protective Top Coat (Volitelný) – Clear lacquer or anti-tarnish sealant.

3.2 PVD (Fyzikální depozice par) Povlak

  • More Durable Than Electroplating – Resists scratches & fading.

  • Used in Luxury Jewelry – Longer-lasting shine.

3.3 Pulse Plating vs. Traditional Plating

  • Pulse Plating – Creates a denser, more even gold layer.

  • Traditional DC Plating – Cheaper but less uniform.

4. Protective Coatings & Sealants

4.1 Clear Lacquer Coating

  • Pros:

    • Creates a waterproof barrier.

    • Inexpensive & easy to apply.

  • Nevýhody:

    • Can wear off over time.

    • May cause allergies if low-quality.

4.2 Anti-Tarnish Solutions

  • Jewelry Shield Sprays – Temporary protection.

  • Silicon-Based Sealants – Longer-lasting than lacquer.

4.3 Wax or Oil Coating (For Storage)

  • Beeswax or Jewelry Wax – Protects during shipping/storage.

5. Proper Storage & Handling During Production

5.1 Preventing Tarnish Before Sale

  • Anti-Tarnish Paper or Strips – Absorbs sulfur in packaging.

  • Airtight Polybags – Reduces air exposure.

5.2 Humidity-Controlled Storage

  • Silica Gel Packs – Keeps moisture away.

  • Dehumidifiers in Storage Rooms – Ideal for tropical climates.

6. Post-Production Care & Tipy na údržbu

6.1 Cleaning Gold-Plated Silver Bracelets

  • Do’s:

    • Use a soft microfiber cloth.

    • Clean with mild soap + lukewarm water.

  • Don’ts:

    • Vyhněte se jedlá soda, toothpaste, or harsh chemicals.

    • Nikdy scrub aggressively.

6.2 Nosit & Care Instructions for Customers

✔ Odstraňte před plaváním/sprchováním.
✔ Avoid contact with perfume & lotions.
✔ Uložte v suchu, airtight jewelry box.

7. Kontrola kvality & Testovací metody

7.1 Test v solném spreji (ASTM B117)

  • Simulates long-term exposure to humidity.

  • Checks plating durability.

7.2 Rub Test (ISO 3160-2)

  • Measures resistance to friction.

7.3 XRF Testing for Plating Thickness

  • Ensures gold layer meets specifications.

8. Udržitelné & Long-Lasting Solutions

8.1 Recyklované stříbro & Eco-Friendly Plating

  • Cyanide-Free Gold Plating – Safer for workers & environment.

8.2 Educating Customers on Longevity

  • Include care cards with purchases.

  • Offer replating services.

Závěr: Key Takeaways for Oxidation-Resistant Gold-Plated Bracelets

By implementing:
✅ Vysoce kvalitní 925 stříbro + thick gold plating
✅ Protective undercoating (rhodium/nickel)
✅ Anti-tarnish balení & storage
✅ Proper cleaning & maintenance guidelines

Jewelry makers can drastically reduce oxidation and ensure their custom gold-plated silver bracelets stay beautiful for years.
