Absorption varies greatly by specific chemicals and the route of exposure. For skin, oral or respiratory exposure, the absorbed dose is only a fraction of the exposure dose (external dose). For substances injected or implanted directly into the body, exposure dose is the same as the absorbed or internal dose.

Absorption: no darkening very slow penetration water bead retains a high, rounded shape this is raw, unsealed sandstone from thailand. It has all the appearance of a high absorption stone, but surprisingly is very low absorption. This is a perfect example of why you should not believe anything about a surface type until you test.
