|---|---|
| General | |
| Product Name | Absolute Black Granite – Honed Hearth Grade |
| Material Type | Natural granite |
| Category | Fire hearth slab / fireplace stone |
| Country of Origin | India |
| Thickness Options | 20mm, 30mm + 50mm |
| Colour Description | Deep black background with fine natural mineral specks and subtle crystal structure, deepening further when sealed. |
| Surface Finish | Machine-honed, smooth and flat surface with a low sheen / matte finish. |
| Natural Variation | Generally uniform appearance with low variation in tone; natural speckling, crystal movement and subtle shading remain visible in the honed finish. |
| Edge Finishing Notes | Edges are clean-cut, sawn finished not than honed like the surface. Minor saw lines or slight tonal differences along the edge may be visible and are typical of natural granite processing. |
| Weight | Approx. 80–90 kg per m² at 30 mm thickness. |
| Density | Approx. 2,900–3,050 kg per m³. |
| Technical Characteristics | |
| Heat Absorption / Retention | Excellent thermal mass — absorbs heat and releases it slowly. |
| Max Temperature Resistance | Approx. 500–600 °C. Must not contact open flame. |
| Compressive Strength | Approx. 150–250 MPa. |
| Flexural Strength | Approx. 15–30 MPa. |
| Porosity | Low; honed surfaces may show marks more readily if unsealed. |
| Water Absorption | Approx. 0.2–0.5%. |
| Thermal Conductivity | Approx. 2.5–3.5 W/mK. |
| Chemical Sensitivity | Good resistance to most household chemicals; prolonged contact with strong acids or alkalis may alter the surface appearance. |
| Stain Resistance | Good; sealing is recommended, especially in front of stoves or open fires. |
| Salt Sensitivity | Low. |
| Natural Characteristics | |
| General Nature | Absolute Black Granite from India is a dense, fine-grained igneous stone with a tight crystal structure. The surface is mechanically honed to create a flatter, smoother finish while retaining its natural mineral speckling and subtle movement. |
| Colour Profile | Although marketed as “absolute black”, genuine granite will show fine specks and slight tonal shifts rather than a flat, jet-black paint-like finish. When sealed, the colour deepens to a rich, uniform-looking black while the natural speckle and grain remain visible on close inspection. |
| Mineral Movement | Natural crystal distribution creates tiny specks, pinpoints of lighter or darker minerals and some mottling. Occasional faint lines or changes in grain direction may be present and are typical of natural granite. |
| Honed Surface Features | The honing process may produce faint tooling lines, micro-pits, slight sheen variation and small filled areas within the surface. These are normal characteristics of honed granite and do not affect performance. |
| Natural Markings | You may see small natural fissures, crystal clusters, pinpoint pits, darker or lighter specks and subtle flow lines. These are inherent features of granite and should be expected in a genuine stone hearth. |
| Pyrite / Metallic Inclusions | Occasional tiny metallic or reflective mineral flecks may appear within the stone or on cut edges. These are natural inclusions and not faults. |
| Production Enhancements | Enhancements may include resin or epoxy fillers, localised smoothing, edge refinement and colour-enhancing treatments. These are standard practices for honed natural granite. |
| Application & Packaging | |
| Suitable For | Fire hearths, stove bases, inglenooks, chamber floors. |
| Application | Internal use only. |
| Sealing | Strongly recommended to deepen colour, reduce fingerprinting and improve resistance to marking. |
| Installation Notes | Install on a stable, level substrate. Keep away from direct flame and allow suitable movement joints where required. |
| Packaging | Supplied on wooden pallets/crates with protective layers. |
| Availability | Cut-to-size: 20mm, 30mm and 50mm |
