Technical characteristics

Rosa Portugal
  • Density: ~2710 kg/m3
  • Water absorption: 0.05% (almost zero)
  • Open porosity: about 0.20% (very dense stone)
  • Compressive strength: ~74 MPa (740 kg/cm²)
  • Bending strength: ~15 MPa
  • Impact strength: ~50 cm (according to the ball drop test – quite a viscous stone)
  • Wear resistance: 2.6–3.4 mm (depending on cutting direction and type of load)
  • Mineralogy: ~98% calcite, quartz impurities <1%
  • Resistance to chemical reagents: good for marble (not afraid of weak acids, but like all calcite, can be etched by strong acid - protective impregnation for kitchen surfaces is recommended)

Rosa Aurora
  • Density: ~2710 kg/m3
  • Water absorption: 0.10% (within the norm for dense marble)
  • Compressive strength: ~75–93 MPa (depending on cutting direction and vein content)
  • Bending strength: ~14–15 MPa
  • Porosity: ~0.2% (minimum)
  • Wear resistance: ~3 mm (practically does not wear out indoors)
  • Frost resistance: conditionally frost-resistant (for outdoor work, impregnation is recommended to avoid microcracks when water freezes in the pores)

Branco Estremoz
  • Density: ~2710–2711 kg/m3
  • Water absorption: 0.07% (practically does not absorb water)
  • Open porosity: ~0.18%
  • Compressive strength: ~94 MPa (960 kg/cm²); after freezing cycles ~75 MPa, which indicates high frost resistance
  • Bending strength: ~14–27 MPa (depending on the sample)
  • Wear resistance (according to abrasion test): 3.4 mm (high abrasion resistance)
  • Mineralogical composition: ~99% calcite (high homogeneity)

Estremoz Creme
  • Density: ~2720 kg/m3 (slightly higher than pure white marble, due to impurities)
  • Water absorption: ~0.07–0.10% (very low)
  • Open porosity: ~0.20%
  • Compressive strength: ~86–93 MPa (850–950 kg/cm²), after freezing cycle ~78 MPa – frost resistance confirmed
  • Bending strength: ~14–18 MPa
  • Wear resistance: 2.2–3.4 mm according to the Boe hme test (sufficiently resistant to abrasion)
  • Colour fastness: does not fade in the sun, suitable for outdoor use (retains colour for years)
