What is Marble SER?
Marble SER is Marble in the SER grade — green silicate-based 'marble' — tougher and much more acid resistant than carbonate marbles, but prone to moisture-sensitive veining and shop-setting. Marble SER has a tensile strength of 12 MPa (1.74 ksi), weaker than 68% of natural material grades. Elongation at break is 0.02% and the elastic modulus is 60 GPa (8.7 Msi). Marble SER has a density of 2.75 g/cm³ (0.0994 lb/in³), heavier than 96% of natural material grades. CAL is the default condition FabDigit quotes; SER is available on request or by drawing note.

- Conducts heat well — 2.6 W/m·K (1.5 BTU/hr·ft·°F), better than 94% of natural material grades
- Polishes to a fine finish — 88/100, better than 94% of natural material grades
- Tough — resists crack growth — 1.2 MPa·√m (1.09 ksi·√in), better than 93% of natural material grades
Limitations
- Limited ductility — 0.02%, worse than 100% of natural material grades
- Heavy — 2.75 g/cm³ (0.0994 lb/in³), worse than 96% of natural material grades
- Difficult to machine — 50/100, worse than 91% of natural material grades

Chemical & Environmental1
Corrosion resistance is good (55/100), better than 69% of natural material grades.
Sustainability4
Producing a kilogram of Marble SER takes about 3 MJ of energy and emits 0.16 kg of CO₂ — less than 87% of natural material grades. Typical recycled content is 0%.
Manufacturability2
Marble SER's machinability is fair (50/100, worse than 91% of natural material grades).

Working with Marble SER
Is Marble easy to machine?
Cut and profiled with water-cooled diamond blades, wire saws and CNC routers; keep feeds moderate and support the slab to avoid edge chipping and vein-line fracture.
Can Marble be welded?
Not weldable — sections are joined mechanically (anchors, kerf clips) or with epoxy/polyester stone adhesive and dowels.
Can Marble be formed, bent or molded?
No plastic forming; shape only by sawing, carving, waterjet inlay and hand tooling — thin panels below ~20 mm need resin-fiberglass or honeycomb backing.
What surface finishes work on Marble?
Takes a mirror polish with progressive diamond/tin-oxide abrasives; honed, brushed, flamed (calcite only) or sandblasted finishes are common, and an impregnating silane/siloxane sealer plus acid-free cleaners are needed to protect the polish.
Marble chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| CaCO3 (calcite)principal mineral of calcitic marble | 80 – 99 | 95 |
| MgCO3 (as dolomite)up to ~45 % CaMg(CO3)2 in dolomitic marble | 0.5 – 15 | 2 |
| SiO2quartz / silicate accessory minerals | 0.1 – 5 | 1 |
| Al2O3clay/mica impurities | 0.05 – 2 | 0.3 |
| Fe2O3 + MnOsource of veining and colour | 0.02 – 1.5 | 0.2 |
| accessory minerals (graphite, pyrite, secontrols colour and staining risk | 0 – 5 | 0.5 |
Marble SER — frequently asked
What is Marble SER used for?
Marble SER is typically used for countertops and vanity tops, sculpture and monuments, interior flooring and wall panels, decorative tile and building facades. In short: highest polish of stones; acid-sensitive interior stone; moderate carving workability.
What is the tensile strength of Marble SER?
Marble SER has a typical tensile strength of 12 MPa (1.74 ksi) — weaker than 68% of natural material grades. Strength varies by condition: see the 4 listed tempers.
Is Marble SER easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 91% of natural material grades). Cut and profiled with water-cooled diamond blades, wire saws and CNC routers; keep feeds moderate and support the slab to avoid edge chipping and vein-line fracture.
Can Marble SER be welded?
Not weldable — sections are joined mechanically (anchors, kerf clips) or with epoxy/polyester stone adhesive and dowels.
What surface finishes work on Marble SER?
Takes a mirror polish with progressive diamond/tin-oxide abrasives; honed, brushed, flamed (calcite only) or sandblasted finishes are common, and an impregnating silane/siloxane sealer plus acid-free cleaners are needed to protect the polish.
Can Marble SER be formed, bent or molded?
No plastic forming; shape only by sawing, carving, waterjet inlay and hand tooling — thin panels below ~20 mm need resin-fiberglass or honeycomb backing.
What is the maximum service temperature of Marble SER?
Marble SER is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
