Pumice
Pumice is a lightweight volcanic rock that floats on water. It is formed when lava cools quickly and traps gas bubbles inside, creating a porous and abrasive texture.
Appearance
The Pumice is a very lightweight rock, typically white, gray, or cream. It has a distinctive foamy, sponge-like appearance due to countless tiny gas bubbles trapped within it. This makes its texture rough and airy, unlike any other common rock.

Special abilities
Ability
Float Power
Pumice has low density due to its porous structure, allowing it to easily float on water after volcanic eruptions.
Ability
Scrubbing Strength
Pumice is made of volcanic glass shards, making it an excellent natural abrasive for polishing and cleaning.
Ability
Insulation Shield
Pumice contains trapped air bubbles, which gives it excellent insulating properties against heat and cold.
