1. Certified Composition and Manufacturing Standards

Premium Sintered Stone should be made from high-purity natural minerals such as quartz, feldspar, and silica, fired above 1,200°C and pressed under 30,000 tons of force. These extreme conditions ensure the slab achieves A1-level fire resistance (non-combustible) and excellent thermal stability, making it ideal for kitchens, outdoor façades, and public spaces.

2. Hardness and Density Matter

The Mohs hardness of a good sintered stone should reach 6 or higher, meaning it can resist scratches from knives, keys, or metal objects. Meanwhile, the water absorption (permeability) rate must be 0 — a hallmark of a true Sintered Surface. This dense, non-porous structure guarantees resistance to stains, acids, and temperature shock.

3. Surface Fineness and Edge Quality

Inspect the cutting edges — clean, smooth, and free from chipping are signs of precise fabrication. The surface texture should appear natural and uniform without visible pores or uneven glaze. Premium slabs exhibit fine-grained structure and subtle reflection under light, demonstrating excellent firing and polishing control.

4. Pattern Sharpness and Color Consistency

With modern digital inkjet technology, high-end sintered stones achieve deep, layered veining comparable to natural marble. Evaluate whether the pattern remains sharp, continuous, and color-consistent across multiple slabs — this reflects top-tier printing and batch control standards.

High-quality sintered stone is defined not just by beauty but by science — its A1 fire rating, Mohs hardness ≥6, zero permeability, and flawless finish guarantee exceptional durability and design value. Whether used in kitchens, façades, or luxury interiors, choosing the right slab ensures lasting aesthetics and safety for years to come.
