What is the density of Coffee Wood Marble?
About 2.70 grams per cubic centimetre, which is 2,700 kilograms per cubic metre. It is ordinary for a calcitic marble and it is the figure that turns a slab's size into its weight.

About 0.3 to 0.4 per cent by weight, which is low. Absorption is measured as a percentage of the dry weight under ASTM C97, and it is one of the two figures ASTM C503 uses to classify a marble.
About 95 to 100 megapascals, measured under ASTM C170. It is a strong stone in the sense that matters for a floor and a wall, and it is not a stone you should be designing a structural member around.
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.
About 12 to 14 megapascals, measured under ASTM C880. This is the figure that governs a wall panel, because a panel is held at its edges and carries itself across the back.
