What is quartz countertop actually made of?

Quartz countertops are not natural stone slabs cut from a quarry. They are engineered surfaces made from about 90-93% crushed quartz crystal combined with polymer resins and colorants. The result is a non-porous, consistent slab that resists staining better than most natural stones.

How do Chinese quartz manufacturers differ from European or American brands?

Chinese manufacturers typically offer competitive pricing and flexible customization for cut-to-size projects. Many focus on export volumes to architects, contractors, and dealers rather than consumer retail. The quality range is broad, so specification and inspection matter more than origin alone.

What should I check when evaluating a Chinese quartz supplier?

Look for clear material sourcing, in-house processing capability for custom cuts and edge profiles, and traceable quality inspection before shipment. Reputable exporters also follow three standards: consistent quality, reliable delivery schedules, and on-time shipping with export-grade packaging.

How does quartz hold up after years of daily kitchen use?

Quartz is scratch-resistant and does not require sealing like natural stone. Over time, the surface stays stable under normal cooking and cleaning. The main thing to avoid is prolonged exposure to high heat directly on the slab, which can damage the resin binder. With proper care, a well-made quartz countertop lasts many years without significant wear.
