# Manten stone

Blue-black stone laced with thin white veins, a sharp and dramatic focal rock.

## What the simulation uses

- Holds water: 1 % by volume (Water it keeps after draining; the rest runs down to the drainage.)

- Pore space: 2 % by volume (Room for air and water between grains; low means roots suffocate when wet.)

- Weight: 2600 g/L (How heavy a litre is.)

- pH: 7 to 7.5 pH (How acid it keeps the soil.)

## Description
Blue-black stone laced with thin white veins, a sharp and dramatic focal rock. It is dense, holds almost no water and stays near neutral.

Also called manten rock.

Estimated, where sources were thin: look authored for the app; physical values estimated.
