I. Appearance Features
The sesame black stone features a deep black base with evenly distributed fine silver-gray crystals on the surface. These crystals serve as a natural embellishment, bestowing the stone with unique textures and a sense of quality. Its appearance is dignified and sophisticated, neither monotonous nor lacking in elegance. It can blend seamlessly with various design styles such as modern minimalist, new Chinese, and European, adding a subtle sense of high-end sophistication to the space.
II. Physical Properties
- Hardness and Strength: The sesame black stone has an extremely high hardness, second only to Chinese black, with compressive strength exceeding 200MPa. It can withstand frequent foot traffic and vehicle碾压, making it suitable for use in public places with high pedestrian traffic.
- Wear and corrosion resistance: The stone surface is dense, with excellent wear resistance and good acid and alkali resistance as well as weather resistance. Even when exposed to outdoor environments for a long time, it maintains its appearance integrity and color stability.
- Water Absorption & Freeze-Thaw Resistance: Low water absorption rate, typically below 0.5%, offering excellent freeze-thaw resistance. In cold northern regions, it's less prone to cracking or peeling even after repeated freeze-thaw cycles in winter.
- Non-slip and easy maintenance: The surface finish of the sesame black stone is diverse, including fire-burnt and lichee textures, offering good non-slip properties. Routine maintenance is cost-effective, simply requiring a rinse with clean water to keep it clean.
