Notes
-
Calcareous onyx is a sedimentary stone prized for its translucency, commonly used for decorative backlit panels and interior design
-
Though relatively soft (~Mohs 3–4), it exhibits good compressive strength (50–110 MPa) and moderate abrasion resistance (~1.0–1.8 g/cm²)
-
With water absorption under 0.5%, it’s suitable for indoor use and can be applied in controlled-glowing elements, provided it’s properly sealed .
