"Porosity is a measure of how much of a rock is open space. This space can be between grains or within cracks or cavities of the rock."
"Permeability is a measure of the ease with which a fluid (water in this case) can move through a porous rock."
Porosity becomes useful to know when, say, you want to determine how quickly a chemical spill might enter an underground water supply.
Hope this helps.
Basalt stone is typically low to moderately porous, meaning it can absorb some liquids if left untreated. The porosity of basalt can vary depending on the specific type and finish of the stone. It is recommended to seal basalt to reduce its porosity and protect it from stains.
Pumice is a type of stone that floats on water due to its high porosity and low density.

Blue stone, often referring to a type of sandstone or bluestone used in landscaping and construction, can be somewhat porous. The porosity depends on the specific composition and density of the stone; some varieties have a higher porosity, allowing moisture and air to pass through, while others are denser and less absorbent. Generally, it is advisable to seal blue stone to prevent water absorption and staining, especially in outdoor applications.
big particles=low porosity small particles=high porosity

When a building is made a stone is placed there to mark its start.
Pitch stone typically has a density around 2.3 - 2.8 g/cm³, depending on the specific composition and porosity of the sample.
how do we calculate porosity of ceramic?
Porosity is the formation of bubbles in the weld.
poorly sorted = low porosity well sorted = high porosity
