By bathstone I assume you mean Pumice which is a volcanic rock with bubbles of gas trapped inside. And yes, it is usually porous
water The answer is actually permeable.
Yes, basalt is generally considered a dense and non-porous rock due to its fine-grained texture and low porosity. However, there can be variations in porosity depending on factors such as vesicles or fractures within the basalt.
No, gabbro is not a porous rock. Gabbro is a dense, coarse-grained igneous rock that is formed from the slow cooling of magma beneath the Earth's surface. It typically does not have significant porosity or permeability.
A porous bag is a bag that has small holes in it, allowing the powders or leaves or whatever is inside it to come out. A tea bag is a porous bag.
Gritstone is porous because it is composed of compacted sand grains that have tiny spaces between them. These spaces allow water to seep into the rock, making it porous and allowing for the rock to absorb water.
There are two types porous and non porous. You can also seel porous concrete to make it non porous.

Silk is porous -- it absorbs liquids.
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
more porous
The story proved to be quite porous. Lava is a porous rock.
Stainless steel is not inherently porous, as it is a non-porous material.
All natural store is porous and needs to be sealed. Travertine is the most porous over marble and granite
A sponge is very porous.
Gunite is a type of sprayed concrete, and is basically as porous as concrete is.
Yes. Chalk is a porous rock.
marble is porous and stains easily
