Pumice is a volcanic rock. It forms when a volcano erupts gas-rich molten rock. Some of this may form a sort of foamy lava which cools rapidly from an extremely high temperature, locking the bubbles in place.

What is the metamorphic form of pumice?

The metamorphic form of pumice is known as "pumiceite." This form of metamorphic rock is created through intense heat and pressure acting on pumice, which causes it to recrystallize and change its mineral composition. Pumiceite typically has a more compact and dense structure compared to pumice.


Why pumice stone pieces are added to boiling water?

Pumice stones are added to boiling water to help retain the heat for a longer period of time. This allows the water to stay hot for a longer duration, which can be especially useful for tasks like cooking or providing warmth.
