How hard is Coffee Wood Marble?
Reference photographs. They show the material and the finish; they are not photographs of goods we made, and the colour on screen is not a colour-match.
The figures, and where each one comes from
| Material | Approximate Mohs |
|---|---|
| Talon | 9 |
| Quartz | 7 |
| Granite | 6 to 7 |
| Coffee Wood Marble and other marble | about 3 |
| Limestone | about 3 |
Why it behaves the way it does
Hardness is what decides the maintenance regime and nothing else. A stone at Mohs 3 in a corridor loses its polish long before it loses its substance, and the fix is restoring the finish rather than replacing the floor.
What these figures are, and what they are not
The Mohs figure is a geological reference for the material and it is not a wear rating for a floor. We do not hold a wear figure for this stone.
If you are specifying this
We have not published products against this question yet. Send us the process, thickness and quantity and we will quote it against what we can actually form, rather than against a catalogue.
About 3 on the Mohs scale, which is the hardness of marble and about the hardness of copper. It will scratch from a coin, it will dull a knife, and it will etch from an acid. None of that is a defect; it is what a marble is.
