1. Nickel-Free Silver Jewelry: Safety & Toegeeflikheid

1.1 Why Nickel-Free?

  • Velveiligheid: Nickel is a common allergen, causing contact dermatitis in 10–20% of the population.

  • Regulatoriese nakoming: Meets EU Nickel Directive (Bereik), Kaliforniese voorstel 65, and other international standards.

1.2 Materials Used in JINGYING’s Nickel-Free Jewelry

Materiaal Komposisie Eienskappe
925 Sterling silwer 92.5% Silwer + 7.5% Koper (Nickel-Free Alloy) Hipoallergeen, tarnish-resistant with proper coating
Argentium silwer 93.5% Silwer + 6.5% Germanium Highly tarnish-resistant, brighter than traditional sterling silver
Rhodium-Plated Silver 925 Silwer + Rodiumplaat Scratch-resistant, ultra-shiny, nikkelvry
Gold-Plated Silver 925 Silwer + 18K goudplaat Luukse voorkoms, nickel-free underlayer

1.3 Testing for Nickel Content

  • DMG Test (Dimethylglyoxime Spot Test) – Detects nickel leaching.

  • Xrf (X-straal fluoressensie) Analysis – Ensures compliance with international standards.

2. High-Polish Finishing Techniques

2.1 Poleerproses

  1. Voor-polisering (Rough Finishing)

    • Tuimel – Barrel polishing with stainless steel media for initial smoothing.

    • Indiening & Skuur – Removing casting seams with 600–1200 grit sandpaper.

  2. High-Polish Buffing

    • Muslin Wheel + Diamond Compound – Achieves mirror-like shine.

    • Ultrasonic Polishing – For intricate designs.

2.2 Advanced Finishing Options

  • Mirror Polish – Reflective, ultra-smooth surface.

  • Satin Finish – Soft, brushed look.

  • Florentine Finish – Cross-hatched texture.

3. Tarnish-Resistant Coatings

3.1 Why Jewelry Tarnishes?

  • Oksidasie: Silver reacts with sulfur in the air, forming black silver sulfide.

  • Vog & Chemicals: Perfume, sweet, and chlorine accelerate tarnishing.

3.2 JINGYING’s Anti-Tarnish Solutions

Metode How It Works Voordele
Protective Lacquer (E-Coating) Clear epoxy/polyurethane layer blocks air exposure Invisible shield, lasts 6–12 months
Rodiumplaat Electroplated rhodium layer (0.1–0.3 microns) Scratch-resistant, ultra-bright, long-lasting
Anti-Tarnish Silver Alloys (Argentium) Germanium reduces sulfur reaction Naturally tarnish-resistant, no coating needed
Benzotriazole (BTA) Passivation Chemical dip forms a protective molecular layer Extends shine between cleanings

3.3 Testing Tarnish Resistance

  • Soutspuittoets (ASTM B117) – Simulates years of wear in 24–48 hours.

  • Sulfur Chamber Test – Accelerates tarnish formation for quality checks.

4. Water-Resistant Jewelry

4.1 Why Water Resistance Matters

  • Daaglikse dra: Showers, swimming, and handwashing can damage jewelry.

  • Lang lewe: Prevents corrosion and loosening of gemstone settings.
