Testing
- Water Absorption:
- 0.35%<
- Density:
- 2680 - 2720 kg/m³
- Flexural Strength:
- 20 - 25 MPa
- Compressive Strength:
- 100 MPa>
- Stone texture:
- a striking multicolor natural quartzite that typically features a rich palette of warm red, pink, gray, blue, brown, and black tones flowing together in organic wave‑like veins and patches that create dynamic movement and bold visual interest in each slab. Its appearance often shows vibrant contrasts between deeper hues and lighter areas, making it well‑suited for feature walls, countertops, floors, and other high‑impact applications where a dramatic, natural surface is desired. In terms of texture and structure, like other Brazilian quartzites, it has a dense, crystalline grain with a generally smooth and durable surface that can be finished in polished, honed, brushed, or other treatments to highlight its natural texture; the inherent quartz content gives it a firm, hard structure and a shimmering crystalline quality under light, while its multi‑tonal pattern makes each piece unique.
Description
Colibri Rubi Quartzite is an exquisite and vibrant natural stone quarried in Brazil, known for its striking multicolor appearance. With an array of warm reds, pinks, grays, blues, browns, and blacks, it creates dynamic visual interest with its organic wave-like veins and patches. This quartzite is perfect for creating stunning feature walls, countertops, floors, and other applications where a dramatic, eye-catching surface is desired.
Physical and Mechanical Properties:
- Water Absorption: Typically low, less than 0.35%. Offers high resistance to moisture, making it suitable for wet areas.
- Density: Approximately 2,680 - 2,720 kg/m³. Contributes to its durability and structural integrity.
- Flexural Strength: Generally ranges from 20 to 25 MPa. Provides resistance to bending and ensures durability.
- Compressive Strength: Typically above 100 MPa. High compressive strength gives it excellent load-bearing capacity.
- Hardness: Mohs scale rating of 6.5 to 7. Comparable to granite, making it resistant to scratching and abrasion.
- Porosity: Low porosity contributes to its stain resistance and durability.
- Slip Resistance: Varies depending on the surface finish. Polished surfaces may be more slippery when wet compared to honed or brushed finishes.
Chemical and Mineral Composition (% by weight):
- Quartz: 85-95%. Dominant mineral providing hardness and crystalline appearance.
- Feldspar: 5-10%. Adds to the stone's strength and durability.
- Mica: 1-3%. Contributes to the shimmering effect and adds a touch of elegance.
- Iron Oxides: Trace amounts. Responsible for red, pink, and brown hues.
- Other Minerals: Minor percentages of other silicate minerals may be present.
Usage and Maintenance:
Applications:
- Suitable for countertops, flooring, feature walls, bathroom vanities, backsplashes, and outdoor applications.
- Ideal for areas requiring a durable and dramatic natural stone surface.
Maintenance:
- Requires regular cleaning with mild soap and water.
- Periodic sealing recommended to maintain its appearance and enhance stain resistance.
- Avoid harsh chemicals or acidic cleaners to prevent damage.
Common Surface Finishes:
- Polished: High gloss and reflective, enhancing the stone's colors and patterns.
- Honed: Smooth and matte finish, reducing gloss while maintaining color.
- Brushed/Leathered: Textured finish for added tactile interest and slip resistance.
- Other Finishes: Such as flamed or sandblasted may be available for specific requirements.
Colibri Rubi Quartzite is not only a beautiful choice but also a practical one due to its durability and resistance to various physical and chemical stressors. Its unique appearance ensures that no two slabs are identical, adding a touch of exclusivity to any project.
