-Magnetite-
Description & Features
Coante’s Essence line includes Magnetite in its Pure series: a dark, homogeneous grey without strong patterns. The surface is a deep graphite grey with a dense, fine grain of black and a few lighter particles, like fine salt-and-pepper sand, evenly distributed over the whole slab; as there are no veins, joints and pieces match each other easily. Coante, with a 105,000 m² plant in Muğla and an annual capacity of about 2 million m², makes the material from quartz grains, polyester resin and pigments with Breton technology. Its test data give impact resistance above 3.36 J on a 20 mm specimen, flexural strength class F4 (above 35 MPa) and water absorption class W4, below 0.07%. There are two slab sizes – Jumbo 330 × 164 cm and Medium 310 × 152 cm – 15, 20 or 30 mm thick, with a polished or Leather finish. It is suitable for kitchen countertops and islands, bathroom vanity tops, wall cladding, interior stairs and floors, and creates strong contrasts with white or wooden furniture. It needs no sealing: a damp cloth is enough for daily care, with a trivet under hot cookware and no harsh chemicals.

| Country of Origin | Turkey |
| Production site | Muğla, south-west Turkey – Coante plant |
| Color & Pattern | Deep graphite grey with a dense, fine black grain and a few lighter particles, no veins |
| Hardness (Mohs) | 7 (Coante data) |
| Density (g/cm³) | 2–2.5 (Coante data, EN 14617-1) |
| Water Absorption (%) | < 0.07 · class W4 (EN 14617-1, Coante data) |
| Flexural Strength (MPa) | > 35 (class F4, EN 14617-2 – Coante data) |
| Frost Resistance | Freeze–thaw resistant (EN 14617-5, KMf25 = 0.98); Coante lists only interior applications and gives no UV data, so it is not recommended for exterior surfaces in permanent sunlight (the resin can change colour) |

Export & project supply
SKARIS MARBLE supplies Magnetite to stone importers, fabricators, architects and hotel projects outside Greece. From our facility in Thessaloniki we handle the whole order in-house:
- Slab selection and matching – we grade and match the slabs for colour and veining, so a large order stays uniform across the whole project.
- Cut-to-size and finishing – pieces cut, edged and finished to your drawings, numbered per room or elevation and ready to install.
- Mixed shipments – Greek marbles, granites, porous limestone (porolithos) and quartz surfaces can be combined in one order.
- Export packing – crated and labelled for sea or road freight, ex-works Thessaloniki; delivered terms quoted on request.
Send us your drawings or quantities and we will come back with a quotation and availability.
