Gift and decoration suppliers often find that the K9 crystal materials they purchase are being "passed off as superior quality": they have poor transparency, contain internal bubbles, and lack luster after cutting.
To identify the core, focus on three key points: 1. Check purity by examining "lead content"—genuine K9 glass contains at least 24% lead. 2. Use a refractometer to measure the refractive index, which should reach 1.545—30% clearer than ordinary crystal.
"Condition Check: 'No Internal Impurities' — Under strong light, there should be no bubbles or cotton-like impurities, and the edges should remain perfectly clear without any hazy appearance. Cut Inspection: 'Facet Luster' — Authentic pieces undergo 12 meticulous stages of grinding and polishing, ensuring that the facets reflect light evenly without a single scratch, offering a smooth, non-abrasive feel in your hand."
When purchasing, request a material inspection report and examine the item with a UV light (genuine products will show no fluorescent reaction). For bulk purchases, randomly select samples for density testing (density ≥ 2.45 g/cm³).
Adaptation: Choose solid K9 material for ornaments, and opt for hollow K9 material for decorative lights, ensuring a balance between light transmission and texture.
