China Calacatta Lux Quartzite Supplier & Suppliers

Calacatta Marble is a metamorphic rock composed primarily of calcium carbonate (calcite), leaving it soft (Mohs hardness 3-4) and highly susceptible to etching when exposed to acidic liquids (vinegar, lemon juice, wine). In contrast, Calacatta Lux Quartzite is formed when pure quartz sandstone undergoes extreme tectonic heat and pressure, resulting in a crystalline network of 98%+ silicon dioxide (SiO&sub2;). It achieves a Mohs hardness of 7, cannot be etched by standard household acids, and exhibits significantly higher tensile and compressive strength.

Raw blocks are sequentially extracted from the same quarry vein and serialized at the factory yard. Slabs are processed through high-resolution 3D optical surface scanning systems. Before ocean packing, our facility conducts a comprehensive 100% dry-lay in a dedicated 5,000 m² workshop, where architects and QA inspectors receive multi-angle overhead photogrammetric maps and video audits verifying continuous veining and harmonious chromatic transition across bookmatched modules.

Calacatta Lux Quartzite and calibrated granite slabs are secured within IPPC-certified fumigated solid timber A-frames or enclosed wooden crates. The stone face-to-face contact points are isolated using non-marking expanded polyethylene (EPE) foam sheeting and reinforced with heavy-duty polyester strapping. Desiccant packs and industrial polyethylene shrink wrap seal the crates against marine vapor intrusion, while 40-foot open top or heavy-duty dry containers utilize steel corner bracing rated for rough high-sea passages.

Yes. Due to the high crystalline purity of quartz crystals within the white matrix, Calacatta Lux offers exceptional refractive translucency when cut to 18mm or 20mm thicknesses. When paired with high-CRI, diffused LED light panels (3000K to 4000K), the darker veins remain opaque while the background radiates a warm, deep ambient light, creating dramatic architectural focal points in executive lounges, reception desks, and vertical feature installations.

For standard slab bundles (20mm / 30mm polished or honed), dispatch can occur within 7 to 10 days from confirmed deposit. For custom architectural cut-to-size orders (such as CNC bullnosing, mitered waterfalls, CNC sink cutouts, or dry-hung curtain wall bevels), production cycles typically require 20 to 30 days per 5,000 m² batch, backed by direct maritime departures from Rizhao or Qingdao Port.
