What Is Sintered Stone?

Imagine a natural stone — recreated by human technology, refined to perfection, and engineered to endure beyond nature’s limits.
That is Sintered Stone, the revolutionary material at the heart of Black Rock Gress.

Made from pure earth minerals such as Feldspar, Kaolinite, Quartz, and Amorphous Glass, sintered stone is not just an aesthetic surface.
It’s a fusion of nature and technology, crafted to create a solid, beautiful, and nearly non-porous material that redefines surface innovation.

The Process: From Earth to Perfection

The creation of sintered stone involves two critical stages — each mimicking the power of geological formation, but in a controlled, accelerated process.

1. Compacting / High-Pressure Densification

Mineral particles are compacted using industrial rollers applying up to 250 kg/m² of pressure, ensuring even density across the slab.
This extreme compression allows Black Rock Gress to produce large-format surfaces (up to 320×160 cm) with remarkable uniformity and strength.

2. Sintering / High-Temperature Fusion

Once compacted, the material is heated to over 1200 °C, approaching the natural melting point of the minerals.
At this stage, the particles bond at a molecular level, forming a seamless, ultra-dense surface — without the use of resins or chemical binders.

The result: a solid, non-porous surface that is resistant to stains, heat, and scratches — ideal for kitchens, bathrooms, façades, and outdoor installations.

Why Choose Black Rock Gress

Black Rock Gress embodies the philosophy: “Engineered by Nature, Perfected by Technology.”
Each slab combines the visual purity of natural stone with performance that surpasses granite and marble — a modern surface built to last for generations.
