How long does it take for vinegar to dissolve pumice?

Vinegar, which contains acetic acid, can slowly dissolve pumice, but the process is quite slow. Depending on factors like the concentration of the vinegar and the surface area of the pumice, it may take several hours to days for noticeable dissolution to occur. However, complete dissolution could take much longer, and in practical terms, pumice is relatively resistant to vinegar compared to other substances.

When was pumice found?

Pumice is a vesiculated igneous rock, meaning that it has tiny pockets of gas trapped inside. These pockets of gas cause pumice to have a very low density. Pumice is usually (though not always) a felsic rock, meaning that it has a high silica content. It is formed when lava is ejected from a volcano. As it cools, gases come out of solution and form bubbles. These bubbles are trapped as the pumice solidifies. It usually forms in areas where felsic volcanic activity is high, which includes continental hot spots and continental volcanic arcs. Composite volcanoes are highly felsic, so any location where composite volcanoes occur, such as Mt. Fuji, Japan, is a prime location for pumice formation. Other volcano types, such as shield volcanoes or cinder cones, may also produce pumice.


Does pumice rock turn into granite after its process?

no pumice rock does not turn into granite.


Where can you find pumice geode?

Pumice geodes are typically found in volcanic regions where pumice is present, such as areas with active or former volcanic activity. Geode shops, rock and mineral shows, and online retailers specializing in geological specimens may also carry pumice geodes for sale.
