The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

A light, porous volcanic rock filled with gas bubbles. It suggests survival after fire and the strange lightness of ruin.

Detailed Definition
Pumice is a volcanic rock formed when gas-rich lava erupts and cools quickly, trapping countless bubbles inside a hardened foam. Because of these holes, some pumice can float on water despite its fiery origin. In poetry, it offers an image of damage made weightless, a body marked by heat yet carried by a current. Its rough texture and buoyancy can suggest resilience, emptiness, or the unexpected capacity of ruined matter to remain afloat.
Example
Example in poetry:
The pumice stone floated briefly in the tide, a fragment of fire made light by air; A poet may use pumice’s rough surface to describe hands worn down by work; He rubbed the pumice over his memory, trying to smooth the sharpest parts of sorrow; The volcanic pumice scattered across the beach suggests that even an eruption can leave delicate remnants
Additional Notes
Pumice can float because its many bubbles make it unusually low-density. This paradox makes it useful for images of burden, escape, or lightness after catastrophe.
