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.

What is the size of grains in 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.
22. What type of rock is formed when lava cools and fine grain texture is produced which sometimes contains air bubbles?
Pumice

Is pumice metallic or nonmetallic?
