Pumice is so fine grained, it actually doesn't have a grain--because it is a natural volcanic glass. The rough texture is caused by the vesicular nature of the rock--trapped pockets of gas bubbles with sharp glassy edges.
Pumice
Pumice normally doesn't have any grains at all. It would be very unusual for it to have grains. Just like Obsidian, Pumice is cooled too fast to have any grains in it. One of the biggest differences between them is that Pumice is cooled with pockets of air while Obsidian has a glassy look.
how did pumice get here
no pumice rock does not turn into granite.
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.
