Someone asked a very similar question - and had it answered. Rather than merge the two together, I have included a link to the question concerned. Just click the related link for the answer.
It feels like a rock. Your welcome.
Pumice is a volcanic rock that is so full of gas bubbles that is it very light, and rough surfaced.
A pumice stone is commonly used for cleaning and exfoliating skin. It is a natural volcanic rock that has a rough texture which helps to remove dead skin cells and calluses.
Pumice is a light-weight volcanic rock with a rough texture and many hollow spaces formed by gas bubbles during its rapid cooling process.
Pumice, an igneous rock, is generally white to dark gray.
Any igneous rock, if ground down to a smooth face and polished, will be smooth. Any igneous rock, if cut, will display a jagged edge. There is the potential for any igneous rock to be smooth or rough. A pumice may be an exception, but pumice isn't all igneous rocks. Most igneous rocks are not vesicular. Pumice will always be rough. Obsidian is naturally smooth, though not perfect. It has conchoidal fracture, so it may show a smooth face, but this is not always the case. Any rock that has been tossed in a river or on a beach for a few thousand years will be pretty smooth, no matter what it is (except pumice). A rock fresh from the quarry will nearly always be jagged and rough. Due to the crystalline texture of igneous rocks, most will naturally fracture in a way that leaves a rough face, if that is what you meant.
The rock you're describing is likely pumice. Pumice is a volcanic rock that forms when lava cools rapidly, trapping gas bubbles that create its characteristic hollow spaces. It is lightweight and has a rough, abrasive texture, making it useful for various applications, including exfoliating skin and as a lightweight aggregate in construction.
A pumice rock is considered a rock because it is composed of multiple minerals, mainly feldspar and quartz. Minerals are the building blocks of rocks, so pumice is classified as a rock rather than a single mineral.
Pumice is an igneous rock that is commonly used for cleaning and polishing due to its abrasive properties. It is lightweight and has a porous structure which makes it effective for scrubbing and exfoliating surfaces.
It is an igneous (volcanic rock).
Pumice.
no pumice rock does not turn into granite.
